が損傷する。BACKGROUND ART As shown in FIG. 5, a conventional slide valve device includes a bottom plate 2 that is fixed to the side of a container 1 and has a nozzle hole 7 communicating with the interior of the container 1, and a slide plate 4 that is slidably mounted by a hydraulic cylinder 3. It consists of The slide plate 4 is pressed against the bottom plate 2 by a bolt 6 or a toggle mechanism via a surface pressure applying spring 5. (Figure 5 shows the surface pressure applying mechanism using bolts.) The flow rate of molten steel is controlled by sliding the slide plate 4 using the hydraulic cylinder 3, so that the center of the nozzle hole 7 of the bottom plate 2 and the nozzle hole 8 of the slide plate 4 is controlled. Normal casting work, in which the flow rate of molten steel is adjusted or closed by aligning (fully opening) or shifting the valves, requires sliding a large number of times to control the flow rate of molten steel (50 times in the case of a slide valve device installed in a ladle). ~
100 times sliding surface 12 around the nozzle hole
is damaged.

莫大な損害を受け又人災の危険性も大きい。Problems to be Solved by the Invention When the damage to the sliding surface 12 around the nozzle hole becomes large, pieces of solidified iron or brick (hereinafter referred to as foreign matter) get caught in the sliding surface 12, causing the slide plate 4 to slide. The sliding surface overcomes the pressure welding force (force of spring 5) and opens, causing molten steel to flow out in the direction of arrow 9 in Figure 7. If molten steel flows out, it can damage not only the expensive slide valve device but also nearby incidental equipment. There will be huge damage and there will be a great risk of human disaster.

摺動面１２とスライドケース１０の摺動面１１を
完全に平行にする必要がある。 For this reason, slide valve operators pay close attention to the damage to the bricks and the condition of the casting, but even so, several accidents occur each year. If the bottom plate 2 and slide plate 4 are pressed together using only the bolts 6 without using the springs 5, the area around the nozzle hole will be damaged, and even if a foreign object gets caught, the sliding surface 12 will not open due to the rigidity of the bolts 6, but the bolt In order to make pressure contact with only 6, it is necessary to make the sliding surface 12 of the slide plate 4 and the sliding surface 11 of the slide case 10 completely parallel.

作業を継続できなくなる。 If the parallelism of sliding surfaces 11 and 12 is even slightly out of order,
Even if the sliding surface 12 is normal, the slide plate 4 may stop sliding, or when the slide plate slides, a gap is created in the sliding surface 12, allowing molten steel to enter, making it impossible to continue the casting operation.

0. The clamp 14 must be manufactured accurately, but the slide plate 4 is a consumable member and precision machining of the sliding surface 12 and back surface 13 is required to maintain parallelism, which increases manufacturing costs.

The purpose of the present invention is to provide a device that eliminates accidents that cause steel leakage due to opening.In the device of the present invention, when the sliding surface begins to open, the pressure contact force (hereinafter referred to as surface pressure) on the sliding surface increases, and the sliding around the nozzle hole increases. Even if foreign matter gets caught in the surface, the foreign matter will not be cut or broken and the surface will not open. In addition, if a large foreign object gets caught, the opening dimension of the sliding surface (hereinafter referred to as surface opening) is regulated to prevent steel leakage accidents due to surface opening.

できる。 A frame 32 is fixed to the housing 21 with bolts (the bolts are not shown).
They are attached to both sides of the left and right holders 26, 26 in the figure (4 pieces in total). A through hole 30 is provided in the frame 32.
b is provided, and pins 30 protruding from both sides of the spring holder 26 are fitted into the through holes 30b so as to be movable in the direction of the arrow 29. A piece 33 is buried below the through hole 30b at a position perpendicular to the through hole 30b and a through hole 36b (described later), and the pressing force applied to the piece 33 by a surface opening prevention spring 34 and an adjusting bolt 35 is adjusted. It can be adjusted using bolt 35.

ず面開き寸法が規制される。 On the other hand, a wedge through hole 36b is formed in the frame 32 in a direction perpendicular to the through hole 30b, and the wedge 36 is inserted into the wedge through hole 36b. wedge 36
is inserted between the piece protrusion 33' of the piece 33 and the lower end surface of the pin 30. The wedge 36 is fixed by a spring plunger 37 attached to the end of the wedge through hole 36b. The spring plunger 37 has a structure in which a ball is attached to the tip and the ball is pressed by a spring, and when a wedge is inserted, the spring flexes and the wedge is pressed by the ball and can be fixed. The protrusion of the piece 33 protrudes from the lower end of the wedge through hole 36b. Therefore, when the surface opens and the pin 30 of the spring holder moves in the direction of the arrow 29, the piece 33
is pushed down and the surface opening prevention spring is compressed. When the pin 30 moves further and the tip of the piece 33 becomes at the same height as the lower end of the wedge through hole 36b, the spring holder 2
The pin 30 of No. 6 does not move any further in the direction of the arrow 29, and the surface opening dimension is restricted.
次に摺動面の面開き防止の作用を説明する。 Next, the effect of preventing the sliding surface from opening will be explained.

る。 Next, the wedge 36 of the face opening prevention device 31 is inserted between the pin 30 of the spring holder and the piece 33. The insertion depth of the wedge 36 varies depending on the thickness of the bottom plate 22 and slide plate 23. If the bottom plate 22 and slide plate 23 are thinner than the standard thickness, the insertion depth will be deeper, and if they are thicker, it will be shallower. Can be adjusted with 36 insertion depths. The wedge 36 can be stopped at any position by a spring plunger 37. That is, as shown in FIG. 3, the shape of the wedge 36 is such that the tip is inclined, but the front (handle side) side is flat (not inclined). The spring plunger 37 acts on this flat part.The spring plunger 37 has a movable ball inside at its tip and is pressed against the tip by a spring, and the case in which the ball is stored has a tapered tip so that the ball does not fall out. It's summery. If the dimension between the tips of the balls of the spring plunger 37 is made smaller than the thickness of the flat part of the wedge 36, the balls of the spring plunger 37 will be pushed in (the spring will bend) by inserting the wedge 36. , the wedge 36 is pressed by a spring through a ball and stops at an arbitrary position.

できる。 During the casting operation, when foreign matter gets caught in the sliding surface 28 around the nozzle and slides the slide plate 23 and the surface begins to open, the pin 30 of the spring holder moves in the direction of the arrow 29 and releases the piece 33 via the wedge 36. Force is transmitted to the spring 34, and the force of the spring 34 acts to increase the surface pressure, thereby making it possible to cut the foreign object or prevent the surface from opening.

レーム３２の下面４１に当ると、それ以上ばねホ

の突起量３９により規制される。 When the foreign object cannot be cut to a large extent, the surface opening prevention spring 34 flexes to cause the surface opening, but when the wedge 36 hits the lower surface 41 of the frame 32, the pin 30 of the spring holder does not go down any further and the surface opening dimension is reduced to the piece 33.
It is regulated by the protrusion amount 39.

故となる。このためピース３３の突起量３９は漏
鋼事故を起こさない寸法（通常0.5〜1.0mm）にす
る必要がある。 When an opening occurs on the sliding surface, if the opening dimension is small, the molten steel will solidify while passing through the gap in the sliding surface 28, which will not cause a major accident, but if the opening dimension is large, the molten steel will solidify while passing through the gap in the sliding surface 28. It passes through and leaks outside, causing a major accident. For this reason, the protrusion amount 39 of the piece 33 needs to be a size (usually 0.5 to 1.0 mm) that will not cause a steel leakage accident.
面開きが起こり、面開き寸法が押えられると面
圧力が異常に大きくなり、油圧シリンダの推力で

開きによる漏鋼事故を未然に防ぐことができる。 When the face opening occurs and the face opening dimension is suppressed, the face pressure becomes abnormally large, and the slide plate 23 cannot be slid by the thrust of the hydraulic cylinder, making it possible to prevent steel leakage accidents due to the face opening.

収できる。 Also, the protrusion amount 39 of the piece 33 is the same as that of the slide plate 2.
3 and the deformation strain of the slide case 24 and clamp 25 can be absorbed. For example, if the parallelism of the slide plate 23 is poor, the difference in the thickness of the slide plate 23 will make the spring holder 26
moves and the thickness of the slide plate increases, the pin 30 of the spring holder moves in the direction of the arrow 29, and the movement is absorbed by the opening prevention spring 34. When it becomes thinner, the space between the pin 30 of the spring holder and the wedge 36 opens, and errors in parallelism of the slide plate 23 can be absorbed.

すい。 Normally, a surface pressure of 4 to 15 kg/cm 2 is adopted for the sliding surface 28 in consideration of the lifespan of the bricks and the possibility of foreign matter getting caught due to damage to the sliding surface around the nozzle hole.
Increasing the surface pressure has the effect of preventing the surface from opening due to foreign objects being bitten, but on the other hand, the sliding surface 28 of the brick
The life of the plate bricks will be shortened.
On the other hand, reducing the surface pressure can reduce damage to the sliding surfaces of the bricks and extend their lifespan, but on the other hand, if even a small foreign object gets caught in the bricks, it can cause the surfaces to open and lead to steel leakage accidents.

きる。Effects of the Invention The present invention can compensate for these shortcomings. Normally, surface pressure is applied only by the surface pressure applying spring 27, and when foreign matter starts biting into the sliding surface 28, the surface pressure is applied by the surface opening prevention spring 34 and the surface pressure is applied only by the surface pressure applying spring 27. The application springs 27 work together to prevent the surfaces from opening. Therefore, the surface pressure applied by the surface pressure applying spring 27 is set to be weak (4 to 10 kg/cm 2 ), and the surface opening prevention spring 34
By setting a high surface pressure (10 to 20 Kg/cm 2 ), it is possible to extend the life of the plate brick and prevent surface-open steel leakage accidents due to foreign objects being caught.

整により任意に変えることができる。 The surface opening prevention spring 34 uses a disc spring with a large spring constant in order to obtain a large surface pressure, and if the preload is set, the effect of preventing surface opening is large. It can be changed arbitrarily by adjusting.
