Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has been developed to reduce the surface pressure load between the plate brick contact surfaces of a sliding/sliding device (hereinafter referred to as SN device) that controls the pouring of molten metal and the pouring base at the melting point. Regarding the setting method.

The surface pressure between the plate bricks, which is an extremely important valve element in the SN device, can be quickly and properly controlled with one touch by moving the device member parallel to the sliding surface of the device body or inserting it parallel to the sliding surface. This is about how to adjust the settings. (Summary of Prior Art) When an SN device is used in a casting ladle, such as a molten metal container or gutter where melt damage is removed, for example, when performing special and strict work processes such as vacuum casting or continuous casting, It is known to exhibit extremely excellent functionality.

A normal SN device consists of at least two fixed plate bricks and a sliding plate brick with raised nozzle holes, a frame or housing (main body) in which these two plate bricks are assembled in a certain constraint relationship, and two plates. It consists of a mechanism that sets an appropriate surface pressure to prevent hot water from leaking between the contact surfaces of the bricks, and a drive mechanism that moves the sliding plate.

The typical SN device currently in use has its housing fixed to the bottom of the ladle.

A disadvantage of this structure, in which the pair of plate bricks are integrated into the housing, often occurs when replacing consumable parts in the SN device, especially the fixed plate bricks and the sliding plate. (Objective of the Present Invention and Overview of the Invention) An object of the present invention is to improve the above-mentioned drawbacks of current SN devices.

In particular, the main cause of such defects is
The goal is to improve the replacement method and mechanism for consumable parts. SN
The configuration of the device is divided into a housing (main body) and at least two pairs of fixed plate bricks and sliding plate bricks provided with nozzle holes, and the pair of plate bricks can be used alone or separately. The cassette is a composite unit, and the housing is configured to function as a receiver into which the cassette is inserted. According to the present invention, the surface pressure setting method in the cassette type SN device as described above can be divided into several types.

This can be attributed to the format of the cassette and receiver. If we were to give a tentative definition to a cassette, we would call it a cassette if it had a configuration in which the fixed plate brick and the Numatsuki plate brick as valve elements are separated and independent from the SN device, and are finally loaded into the SN device and used. .

Therefore, initially, a bare fixed plate brick and a sliding plate brick, each alone or as a silk material, form a type of cassette.

In the case of @ type cassettes, the surface pressure is set at the same time as the cassette is loaded by providing an elastic element (spring) and adjustment mechanism for setting the surface pressure load on the SN device main body which functions as a receiver.

Naturally, the fixed plate and sliding plate pair can also be combined in a predetermined relationship and housed in a cassette case made of heat-resistant metal material.

The cassette case always has a structure with a surface pressure load setting allowance. However, this type of cassette,
It is subdivided into: That is, there is a type @ in which the cassette is provided with an elastic element for setting the surface pressure load, and a type (■) in which the cassette is not provided with an elastic element.

In addition, the type @ with an elastic element is divided into type (2) which has a surface pressure adjustment mechanism and type (2) which does not have a surface pressure adjustment mechanism. ■When the cassette has an elastic element, as in the case of the type, there is usually no elastic element on the receiver.

However, the surface pressure setting mechanism may be installed on the receiver side. When the cassette does not have an elastic element, as in the case of Type 1, the elastic element is always installed on the receiver side. A special cassette containing only plate bricks,
There is also a type ■ that is divided into cassettes that contain only the elastic elements.

At this time, surface pressure is set by appropriately combining (loading) two types of cassettes. The elastic element here is not limited to a coil spring.

It includes, of course, other types of springs as well as anything that has the ability to apply force or pressure. The @ type cassette has a structure in which the elastic element is fixed, and a structure in which the elastic element moves together with a sliding metal fitting. The outer surface of the cassette case has an appropriate porosity over almost the entire surface or a portion thereof.

For example, there are various cases in which the case is composed of a frame or a wide case. The surface pressure load setting allowance in the cassette case is normally configured to be movable in a direction perpendicular to the sliding direction of the plate.

In some cases, the setting allowance is configured such that a part of the case has a flexibly deformable structure or is made of a weak material. The surface pressure load setting allowance is preferably parallel to the sliding surface of the plate brick, but does not necessarily have to be parallel. If it is movable in the direction of applying surface pressure, the purpose is achieved. The saddle contact between the cassette and the seater is generally on the entire surface of the cassette, but in some cases it may be only on the bottom, or partially on the bottom and both sides.

Its structure is arbitrary. When inserting the cassette,
It doesn't always slide. Sometimes it is inserted while rotating. Everything is configured in relation to the receiver. It is necessary to accurately determine the loading position of the cassette in the receiver, and to fix it to the extent that it does not interfere with operation. The device or mechanism for securing the cassette can be constructed on the cassette itself. However, in many cases it is preferable to provide it not in the cassette but in the L receiver; in some cases, it is provided in both the cassette and the receiver. The fixed plate and sliding plate, which are the valve elements, are made of mortar, fireproof paper,
It is fixed directly to the cassette case, or to a metal frame, etc., by fireproof fabric, set screws, pins, cotters, or other means.

In some cases, even the lower nozzle is integrated.
A guide has been devised to help insert the cassette into the receiver.

The guide is often a cassette case or the receiver itself. In some cases, the guide also serves as means for setting surface pressure and positioning and fixing.
The sliding plate and its driving device may be connected by any mechanism.The cassette is not necessarily placed directly into the receiver provided at the bottom of the container.

There are cases where a plate brick is placed in a cassette case and then press-fitted into a receiver prepared outside the SN device main body, so to speak, an intermediate receiver. At this time, surface pressure is involved at the same time as press fitting. The cassette has a suitable structure so that it connects or fits well into the SN device body or sunken container.

When the force of the spring contained in the cassette becomes weak, a spacer or the like is inserted or a partial adjustment device is provided to correct the pressure.

The receiver is a pot containing the cassette described above.

In addition, elements are provided for guiding, intimately fitting, locating and fixing the inserted cassette. As described above, an elastic element for setting a surface pressure load may be installed on the side of the receiver, and a surface pressure adjustment mechanism may be provided. Elastic elements are not limited to those for compression, but also those for tension can be used. The posture in which the cassette is inserted into the receiver is not limited to being horizontal.

The posture of the molten metal container is also not limited. In order to connect the cassette loaded into the receiver to the SN device main body or the molten metal container, the receiver is moved in a direction perpendicular to the sliding direction of the plate, so that it is closely connected to the container, etc. .

However, the motion of the receiver is not necessarily linear motion, but may also be motion accompanied by rotation or tilting motion, for example. A configuration is also possible in which the cassette is inserted in the sliding direction of the plate and simultaneously connected to the casting nozzle. To move, position and fix the receiver,
Various means are possible, such as a bolt-nut mechanism, a cam mechanism, a toggle mechanism, a cotter, a pin, a hydraulic jack mechanism, and a mechanism using an elastic element (spring).

They may also serve as a surface pressure setting or adjustment mechanism. More preferable operation can be achieved by wrapping the entire SN device with a heat reflector or heat shielding device.

The pressure between the contact surfaces of the fixed plate brick and the sliding plate brick, which can be set up in a wide variety of ways in relation to the various types of cassettes and their corresponding receivers as described above, is If classified as a monarch, it is generally represented by the following aspects.

■ A method in which the surface pressure is set in advance on the receiver side and then the cassette is loaded.

■ Method of loading by performing surface pressure setting operation on the cassette side in advance.

■ A method in which the surface pressure is set in advance on both the receiver and the cassette, and then the cassette is loaded.

■ A method of setting surface pressure by making an elastic element for setting surface pressure load into a cassette and loading it together with a plate brick cassette.

To explain from a more specific standpoint, regardless of whether an elastic element for setting surface pressure load is installed on either the receiver or the cassette, the acting force of the elastic element is used to truly set the surface pressure load. For the purpose of compensating for changes in the applied force, an interposition may be inserted, or an alternative mechanism or structure may be used.

Inclusions, etc. are inserted using an appropriate method and device.

The mode of insertion is divided into a push-in type and a pull-in type. It is preferable that the inclusion is inserted parallel to the sliding direction of the plate brick. However, it is also possible to frame it at right angles to the sliding direction or at any arbitrary angle. In some cases, rotation may be involved. It is also possible to configure the inclusion to be set in advance before inserting the cassette so that appropriate surface pressure is applied simultaneously with the insertion of the cassette.

Reserve equipment would be used for that. The inclusion can be inserted by a gear rack or the like without relying on a sliding movement. (Example) Next, the present invention will be explained by referring to an example shown in the drawings.

In addition, in order to explain the present invention in an easy-to-understand manner, the drawings omit most parts other than the relationship between the receiver and the cassette, so please understand this point. First, in FIG. 9, at least two fixed plates 1 and sliding plates 2 are separated and independent from the SN device main body 6, and only the pair of plate bricks 1 and 2 are combined, and a jig 3 is assembled as a so-called cassette. This shows an embodiment in which the receiver 7 is held in place and attached to the receiver 7.

As is well known, the SN device main body 6, which is fixed directly below the rusting/slip 5 in the ladle-like molten steel container 4, is configured as a frame or housing with a coin structure.

The receiver 7 included in the housing is assembled within the housing under certain mechanical constraints. In particular, the receiver 7 of this embodiment has the SN main body 6
is independent from.

Compression coil springs 72, 72, . . . for setting surface pressure load are mounted on the lower case 71, which is fixed to or supported by the SN device main body.
. . . are installed, and the upper end of the spring 72 is restrained by a spring receiving plate 73 that can be raised and lowered. Above the lower case (also called the lower metal frame) 71, the upper case (also called the upper metal frame)
74 are assembled with bolts 75 to constitute a kind of container that can accommodate the cassette. The sliding frame 76 remounted on the spring receiving plate 73 and the upper case 74 form a space 78 with a width and height that tightly accommodates the cassette.

At the entrance of the space 78, the upper case 74 and the sliding frame 76 are curved so as to widen in the front, forming a kind of guide 79. The fixed plate 1 and the sliding plate 2 are loaded into the space 78 as a combination. At the same time as loading, spring 72...
works, but it's not perfect yet. Receiver 7 is the device main body 6
Appropriate surface pressure can only be applied when the main body 6 is fixed to the bottom of the molten steel container 1. If the receiver 7 is set in the main body 6 from the beginning, it is also possible to implement a method that requires only the insertion of a pair of plate bricks. FIG. 10 shows an embodiment in which a pair of fixed plate 9 and sliding plate 10 are separate and independent and each form a kind of cassette.

In the case of this embodiment, the receiver 8 is included in the SN device main body 6 fixed to the bottom of the container 4 from the beginning. however,
A sliding frame 82 is directly remounted on the lower case 81 which is fixed to the main body 6 or is currently supported.

The upper case 83 is attached to the lower case 81 by bolts 84 and constitutes a kind of container, and the upper case 83 and the moving frame 82 form a space 85 for loading a cassette. This is almost the same as the previous example. A spring 86 for setting surface pressure load is attached to the bolt 84.

In addition, in order to facilitate loading of plate bricks as a cassette, both the fixed plate 9 and the information plate 10 are
The tip and rear ends thereof are provided with tapered tapered portions or rounded portions 9a and 10a as guides. The positions of the guides 9a, 10a are determined by the loading order. Furthermore, such guides may be provided in all or part of the necessary locations from the beginning so that it does not matter which one is inserted first. In the two embodiments described above, the connection between the fixed plate and the casting nozzle 5 and the means for setting or adjusting the surface pressure load are performed by known means such as a toggle mechanism, a cam machine, a foundation, a screw mechanism, etc. good. This point will be understood by the example given below. In order to prevent the loaded plate brick from moving within the receiver or housing, the four sides or any side of the loaded plate brick should be
Other parts may require plate brick fixing mechanisms.

Usually this will be achieved by means such as screws, wedges or cotters. Note that the loading direction of the plate bricks may be any direction as long as it is parallel to the sliding surface.

Next, a pair of at least two fixed plates and a sliding plate is housed in a cassette case to form a roughly finished cassette, which is then loaded parallel to the direction of the plate bricks. An example of the case will be described.

First, FIG. 11 shows an embodiment in which the cassette incorporates an elastic element for setting surface pressure load.

As shown in FIGS. 12 and 13, the cassette 11 includes an upper case 111 and a lower case 11, which constitute a kind of airtight container.
2 are movably connected by bolts 1, 13, etc., using vertical elongated holes that allow a surface pressure setting allowance.

The allowance dimension a at the fitting portion of both cases is the setting allowance. A compression coil spring 114 that applies a surface pressure load is installed on the lower case 1 12, and the upper end of the spring is restrained by a spring receiving plate 115. The fixing plate 116 is fixed to the upper case 111 by mortar bonding or the like. The sliding plate 117 is housed in a sliding metal frame 118, and the metal frame 118 is movably mounted on the spring receiving plate 115. Gold frame 118. A head is coupled to the drive. On the other hand, the receiver 12 of the main body 6 is a container or case with an extremely simple structure that can accommodate the cassette 11 described above.

The cassette entrance has a guide 12 that draws an arc in front of it.
The number is now 1,122. Further, in the deepest part of the receiver 12, there is a positioning pin 124 suspended by a compression coil spring 123, and the loaded cassette 12
It is configured so that it fits into the pin hole 110 of and can be automatically positioned. In this embodiment, the receiver 12 itself and the cases 111, 112 of the cassette 11 may be considered as the main guides.

The actual heights h of the receivers 12 are configured at intervals appropriate for setting the surface pressure in the cassette 11, and the surface pressure can be set at the same time by simply loading the cassette 11. Another example of a cassette incorporating an elastic element is shown in the 14th
It is shown in the figure.

The cassette 10 has a portion of the vertical walls on both the left and right sides of the cassette case 101 that can be flexibly deformed by surface pressure load, or a portion that is weak in material and deforms by surface pressure load, so-called surface pressure load setting. Variable part 1
It is characterized by having 02 and 102.

A sliding metal frame 103 is installed in the cassette case 101, a metal frame 106 containing a sliding plate 105 is placed on top of a spring 104 installed in the metal frame 103, and a fixed plate The configuration in which casing 107 is bonded with mortar to case 101 is almost the same as the previously described example.

However, in the case of this embodiment, it is quite difficult to set the surface pressure in advance before loading the cassette 10.

The surface pressure setting operation will be performed on the side of the receiver or the SN device main body 6. In FIG. 18, the receiver 17 of the SN device main body 6 fixed to the bottom of the molten steel container 4 is shown.
Not only does it accommodate the cassette 18; This shows an embodiment in which the positioning and fixing and setting of the surface pressure load can be performed at the same time. Cassette 18 in this embodiment
As shown in Fig. 19, the upper and lower cassette cases 181 and 1
82 is assembled with a structure that allows a surface pressure setting allowance as described above.

At least two guide pins 183 and 184 protrude laterally from both sides of the cassette 18 at regular intervals, divided into an upper case 181 and a lower case 182. On the other hand, the receiver 17 has the guide pin 18
The feature is that a guide groove 171 into which the parts 3 and 184 slide is provided. In particular, the entrance portion of the guide groove 171 is formed by a straight slope and a curved surface.
, and the part 173 deeper than that has an arbitrary width b
It becomes a parallel guide. Therefore, even if the surface pressure is not set on the cassette 18 in advance, the guide groove 171
If the width b of is designed to be appropriate for setting the surface pressure, the surface pressure can be set simply by loading.

If the cassette 18 is set with an appropriate surface pressure in advance, the width b of the guide groove 171 is simply the width of the two sets of guide pins 183.
and 184 are designed to be loosely restrained. Next, the first
FIG. 5 shows an example in which the cassette does not have an elastic element for setting surface pressure load.

The cassette 13 is as shown in FIGS. 16 and 17.
Upper case 131 and lower case 132 are connected by bolts 133 using vertically long bolt holes,
They are movably connected with a structure that allows for surface pressure setting.

The fixing plate 135 is fixed to the upper case 131 by mortar bonding or the like. The sliding plate 136 is housed in a bog deposit frame 137, and the metal frame 137 is slidably mounted on the lower case 132. Furthermore, slide beams 138 are attached to the upper and lower cases in parallel to the direction in which the cassette is loaded. The beam may be single or multiple. A tapered curved guide 139 is provided at the distal end of the cassette 13. On the other hand, the receiver 14 of the SN device main body 6 is configured as a container or case that accommodates the cassette 13 described above.

In particular, a compression coil spring 142 for applying a surface pressure load is installed on the bottom surface 141 of the receiver 14, and the upper end of the spring is restrained by a spring receiving plate 143. Upper surface 144 of receiver and spring receiving plate 143
form a space 145 that accommodates the cassette 13. However, its spatial height is considerably smaller than the thickness of the cassette 13. Then, when the cassette 13 is loaded with its slide beam 138 aligned with the groove 146 on the receiver side, the spring receiving plate 143 is pushed down.

In other words, the springs 142 work to generate appropriate surface pressure. Other supplementary work is largely unnecessary. The cassette 13 is secured in place on the exit side by a cotter, pin, wedge or other suitable securing mechanism 147. In the case of this embodiment, the cassette case, the seater, the slide beam and its groove play an important role as a guide.

FIG. 20 shows an embodiment in which the elastic element is made into a cassette as a special case in which the elastic element is not incorporated.

In the case of this embodiment as well, the cassette case 151 of the plate brick cassette 15 (the bottom portion 500 also serves as a sliding metal frame holder) has a structure that allows a surface pressure setting allowance.

The fixed plate brick 152 is mortar-bonded to the case. The sliding plate brick 153 is connected to the sliding metal frame 15
4, and has been placed on the bottom of the case. In addition, the springs 191 for setting the surface pressure load are combined with a spring case 192 with a structure that allows compression of the springs.
and 193, forming a kind of spring cassette 19.

The receiver 16 (the bottom part 501 also serves as the lower case) of the SN device main body 6 has the two cassettes 15 and 1 described above.
It is configured as a container that can accommodate 9.

In particular, the cassette storage space accommodates two cassettes 15,
The dimensions are designed to compress the two cassettes by the amount of surface pressure load setting based on the thickness of 19 mm.
Therefore, in this embodiment, the surface pressure load is set by selecting the most suitable spring cassette 19 and loading it together with the plate brick cassette.

As for the spring cassette, as shown in FIG. 21, it may be preferable to provide a spring guide for each spring.

FIG. 22 shows a case using an eccentric cam.

That is, the SN device main body 2 fixed to the bottom of the molten steel container 4
Reference numeral 5 has a configuration in which a receiver 26 that accommodates a cassette 27 configured as described above is supported by eccentric cam shafts 28, 28. When the cassette 27 is inserted into the receiver 26 from the right by passing it through the guide roller 26a that has been re-grained at the entrance of the receiver 26, the drum camshaft 28 is then driven by a drive mechanism (not shown). Maximum about 90o
The receiver 26 is pushed up by the lift of the eccentric cam 28a, and the connection with the coin dispenser/zuru 5 is established.

In the case of this embodiment, the cassette 27 may be loaded after setting the surface pressure in advance.

The operation of the eccentric camshaft at this time is simply to push up the cassette 27 toward the casting nozzle 5 and connect it. When loading without setting the surface pressure in advance, use the camshaft to set the surface pressure as well.
This shows an example of loading by lever operation.

That is, the SN device main body 29 fixed to the bottom of the container 4 accommodates the receiver 30, and the receiver 3 is a cassette (not shown) corresponding to the cassette 27 in FIG.
The container structure is such that it is inserted from the right side. The main body 2 is attached to a bracket 291 fixed to the left side of the main body 29.
A lever 292 that swings along both sides of the frame 9 is hingedly connected by a pin 293. The receiver 301 housed in the main body 29 has support bolts 301 on both sides thereof.
, 301 are mounted horizontally.

The bolt 301 has a fairly long horizontal bolt notch 294 provided on the lever 292, and an innermost hole 295 provided in an arc shape centered on the pin 293 on the side of the main body 29.
It goes through. As a result, ``When Shiba 292 is rotated counterclockwise by human power or a jack or similar device,
The receiver 30 containing the cassette is raised, and the cassette and the casting nozzle 4 are connected.

In the loading position, the cassette can be loaded by firmly tightening the nut 296 or by
97 is fixed to the bracket 298 by some means. Also in this embodiment, the cassette may be loaded after setting the surface pressure in advance.

At that time, the cassette is simply raised using the ladder 292 so that it comes into contact with the mirror nozzle, set in a predetermined position, and fixed. When the surface pressure is not set in advance, the force set is raised sufficiently strongly to set the surface pressure using the lever 292, and then fixed at a predetermined position with the surface pressure applied. FIG. 24 shows a case using a cassette 31 that can be loaded and connected to the coin dispenser/zuru 4 at the same time.

The cassette 31 has upper and lower cassette cases 311, 3
12 is constructed with a silk stand in a structure that allows a surface pressure setting allowance,
At least two fixed plates and a sliding plate are assembled in the container in a fixed constraint relationship as described above.

However, in the case of this embodiment, whether to set the surface pressure before loading or to set the surface pressure after loading is arbitrary depending on the circumstances at the time.In the case of this embodiment, the upper fixed plate 313 It is characterized by having a nozzle portion 314 that projects upward and has a shape and structure that allow easy connection with the rust removal nozzle 5.

As a specific example, as shown in FIG. The bottom surface is made as a sloped surface that matches it.

The SN device main body 32 fixed to the bottom of the container 4 has a receiver 321 that accommodates the cassette 31 opened to the right.

A guide groove 322 that allows the nozzle portion 314 to enter is provided on its upper surface. Therefore, cassette 31
By simply pushing it into the receiver 321, an accurate connection with the mirror nozzle 5 is achieved, and there is no need for any other operation other than closing the opening of the receiver 31 with a lid and fixing it in place. be.

The cassette 40 is fixed by driving in a fixing pin 40b or the like. Also in this embodiment, the cassette 40 may or may not have an elastic element for setting surface pressure load. If there is no spring 391, the spring 391 also works for setting the surface pressure load.
Simultaneously with loading the cassette, setting of the surface pressure load and connection to the dispenser nozzle 5 are performed. Figure 3 shows the SN device main body 4.

FIG. 4 shows an example in which a wedge 44 of an arbitrary slope is inserted and operated instead of the parallel spacer as in the example of FIG. 3.

At this time, it is preferable to provide a curved surface equivalent to the wedge 44 on at least one of the base plate 421 and the spring receiving plate 411. In Fig. 5, unlike the above two examples, a spacer 452 with a rectangular cross section, or a spacer 453 with a circular or circular cross section is inserted under the spring 451. , represents an embodiment in which the surface pressure is set or adjusted now.
