Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a novel rotary wheel and belt type continuous casting machine for casting molten metal.

The machine of this invention uses a thin walled cast rim and a pair of removable mold side members surrounding the thin walled rim.

The various features, features, and advantages of this invention will be more fully understood from consideration of the following description in conjunction with the accompanying drawings.

As shown in Figures 1, 2 and 3, a rotary wheel and belt type continuous casting machine embodying the present invention includes a frame base 20 with an upright frame 21 on which a rotary wheel 2 for a casting wheel is mounted.
2 is rotatably mounted.

The flexible cast belt 24 is guided and supported by four adjusting wheels 26, 27, 28 and 29 along an arcuate path around the outer periphery of the rotating wheel 22.

Pulley 26 is located in the feed or inlet area "E" and is mounted on a pair of parallel arms 30 and 32 actuated by a rod 34 (FIG. 3) and a fluid cylinder mechanism 36. It can be raised from the outer periphery of the rotating wheel 22 in order to open the inlet of the pulley and to adjust the position of the pulley to adapt to different thicknesses of the product to be cast.

The pulley 27 is a cast belt driven pulley;
It is driven by an electric motor 38 operating through a reduction gear box 40 connected to the shaft of the motor.

A tension wheel 28 is used to adjustably tension the casting belt 24.
is mounted on a pair of parallel arms 44 and 46 actuated by a rod 48 and a fluid cylinder mechanism 49.

To operate the casting belt 24, the operating pulley 29 is isolated from the outlet or discharge area "D" and is connected to a pair of yoke bearings 5.
Yoke 50 mounted to swing by 2 and 53
is held by.

This yoke 50 is controlled by a rod 54 and an operating cylinder mechanism 55.

As best seen in FIG. 3, the upright frame 21 has an overall semicircular shape and is mounted on a pair of saddle assemblies 56 and 57.

Thus, the frame 21 can be arranged and fixed at various different positions relative to the base 20 to adjust the angle of supply injection into the mold inlet E.

As best seen in FIGS. 1 and 2, a large movable refrigerant splash shield 51 extends across most of the front of the machine.

The purpose of this splash shield will be explained in detail below.

As shown in FIG. 1, molten material M is supplied from an insulated pouring vessel or drawer and is fed through a nozzle to the entrance E to the mold cavity, which will be described immediately below.

The machine of the invention is particularly suitable for continuously casting molten metals such as aluminum, copper, steel, stainless steel and other alloys of these metals.

Other metals or alloys can also advantageously be continuously cast by the machine of the invention.

The casting P (Fig. 13) is generally discharged from the machine through a discharge area on the opposite side of the wheels from the inlet E (not shown).
It is directed to subsequent processing equipment such as a rolling line or coiler.

Advantageous casting recess “C” for casting molten metal M (FIG. 1)
(FIGS. 4, 7, and 8), the rotating wheel 22 is constructed with a pair of spaced apart circumferential flanges 58 and 59 having the same diameter, and a thin-walled cast rim 60 surrounds the outer periphery of these spaced flanges. It is straddled across.

The rim is in a "floating" relationship with the flanges 58 and 59, ie, the rim is axially assembled over the two flanges with a small circumferential gap between the rim and the flanges.

A pair of mold side members 61 and 6 are provided on both sides of the mold recess C.
2 are provided and are axially assembled in surrounding relationship around the thin rim 600.

These mold side members are in floating relation around the rim and are laterally guided by devices described further below.

As shown in FIG. 4, flexible casting belt 24 extends across the outer periphery of mold side members 61 and 62 to define a fourth surface of mold recess C. As shown in FIG.

As best shown in FIGS. 7 and 8, a thin-walled casting rim 60 and belt 24 define two opposed major mold surfaces, and the rim and belt are strongly cooled by a high velocity flow of refrigerant as described below. .

The rim and belt are formed from a strong, tough heat transfer material, such as mild steel, and they are of approximately equal thickness.

Both are extremely thin as they help to restrain the molten metal as it solidifies.

In a preferred embodiment of this invention, the diameter is 213 cm (
a rim 60 and a belt 2 having a diameter of 7 feet).
4 has a thickness in the range of 0.635 to 1.905 mm (0.025 to 0.075 inches).

As shown, the rim 60 has a diameter of 1.524 mm (0,
060 inches) thick.

Belt 24 is made somewhat thinner than rim 60 because the belt must curve around pulleys 26-290.

Mold side members 61 and 62 are also made of heat transfer material and are cooled indirectly by conduction through the rim and belt.

The size and proportion of the product P (FIG. 13) cast in the recess C can be changed as appropriate.

By removing mold side members 61 and 62 and replacing them with thicker or thinner side members, the thickness of the product is correspondingly increased or decreased.

To accommodate changes in the gap between belt 24 and thin rim 600 caused by varying the thickness of side mold members 61 and 62, inlet pulley 26 is adjusted in position and tensioned by its positioning mechanism described above. The wheel 28 is adjusted in position to accommodate the actual change in the arcuate path through which the casting belt travels due to changes in the radius of this arcuate path.

By bringing the mold side members 61 and 62 closer to each other,
The width of the casting recess C is adjusted to vary according to the width of the casting P.

Ends 60-1 and 6O-2 of thin floating rim 60 (seventh
) is guided laterally on flanges 58 and 59 of rotating wheel 22 by a number of radially flexible ramps 64-1 and 64-2 mounted on the rotating wheel.

One of these radially flexible ramps 64-1 for the outer ends of the belt is shown in more detail in FIG. The skirt member, which includes a fixed mounting block 65, is held in place by a mounting device 68 that is removably attached to the outside of the wheel flange 58 by screws 69.

The radially flexible finger 10 has an end barb 71 that hooks loosely around the rim end 60-1 to create a radial gap to the rim as shown in FIG.

Resilient fingers 70 have right angle bends to form downwardly extending ends 72 which are secured to the inner surface of mounting block 65, such as by soldering.

The fingers 70 and their hooked ends 71 are thus free to curve radially outwardly from the mounting block 65 as the thin rim 60 floats.

Figures 16 and 17 show alternative embodiments of radial rim end clamps 64-IA and 64-IB for the outer rim ends.

In the clamp of FIG. 16, the inner ends of the resilient fingers 10 are soldered to the top of a narrow mounting block 650.

In the clamp 64-IB shown in FIG. 17, the downwardly extending end 72 is brazed to the outside of the mounting block 65.

A clamp such as that shown in FIG. 17 can be used when more radial elasticity is desired.

One dozen outer end clamps 64-1 (or 64-1
A or 64-IB) are uniformly spaced around the rotating wheel 22 and the same number of inner end clamps are provided mirror-symmetrically to each outer end clamp.

As shown in FIG. 7, the inner periphery of the rotary ring 22 is mirror-symmetrical with the outer periphery as a whole, and the protruding cylindrical skirt member 6 is held by a mounting device 68 and screws 69.
Contains 1-2.

A rotating wheel in which the liquid refrigerant applied to the inner surface of the rim is intentionally allowed to expand by an appropriate amount from the outer edges 60-1 and 60-2 of the rim, and in particular the rim from the outer periphery of the rotating wheel flanges 58 and 59. An inflatable resilient sealing device 74 to prevent leakage in the surrounding non-mold area.
-1 and 74-2 are provided near the intermediate surface between the outer periphery of the flanges 58 and 59 and the inner surface of the rim, respectively.

These expandable elastic seal devices γ4-1 and 74
-2 are clearly shown in Figure 15, respectively.
It includes an inflatable tubular seal 75 located between adjacent wheel 7 flange 58 and a number of circumferentially spaced end clamps 64-1.

A valve 76 is provided for inflating and deflating the inflatable tube 75.

These inflatable seals collapse to facilitate replacement of thin-walled rim 60 and mold side members 61 and 62 and re-expand to seal against escape of liquid coolant during casting operations.

9, 10. As shown in FIGS. 11 and 12, the two mold side members 61 and 62 are guided laterally in front of the mold cavity E by a roller guide assembly 77 and in intimate contact with it on the thin-walled rim. They are tightly pressed together.

In the vicinity of the casting recess C, the belt tension is applied to the mold side member 6.
1 and 62 are pressed tightly against the thin rim 60, which rim is seated on the outer periphery of the wheels 58 and 59.

The mold side members 61 and 62 are thus held against lateral displacement over the mold casting area.

In fact, the guide mechanism 17 is connected to these mold side members 61 and 6.
2 on the appropriate guide line.

The guide assembly 71 includes four flanged rollers 78 which have internal anti-friction bearings (not shown) and are mounted on a block 79 fixed to the chassis.

The chassis includes cross plates 80-1 and 80-2 held by a sturdy cross frame 81.

The protective cover 82 extends over the chassis and rollers below the ladle, as shown in FIG.

To hold the roller guide 77 in place, a retaining assembly 84 is provided which is mounted on two heavy brackets 85-1 and 85-2.

These clamps 85-1 and 85-2 are pivoted at 86 to each pulley arm 30 and 32.

A fixing screw 87 in an arcuate groove 88 provides adjustment of the retaining assembly 84.

This retaining assembly 84 also includes mold side members 61 and 62.
Mold element 60 at mold inlet E acting to apply a generally downward pressure against and against the outer periphery of thin-walled rim 60 and corresponding wheel flanges 58 and 59.
．． 61 and 62 to ensure proper alignment.

The retaining assembly 84 includes two spaced apart legs 89-1 and 89-2 that span the opening 90 and allow the introduction of the nozzle N into the mold mass E.

These spaced apart legs 89-1, 89-2 (as shown in FIG. 11) curve downwardly in close proximity to mold side members 61 and 62 to shield them from heat.

Side plate elements 80-1 and 80-2 extend on either side of mold E and carry a pair of lateral guide rods 92-1 and 92-2 to position mold side members 61 and 62 precisely laterally in entry area E. Guided and separated.

A plow or stripper 94 pivotally mounted on a shaft 95 fixed to the frame 21 as shown in FIGS. 13 and 14 cooperates with a roller guide assembly 96 having flanged rollers 78.

A resilient plate 97 carried by mounting block 98 connects roller guide assembly 98 to plow 94 and the plow's stripper mucus 99 applies moderate pressure to the casting surface of thin-walled rim 60.

This cast surface F of the thin rim includes a coating layer to control the amount of heat transfer, and the pressure of the mucus 99 on the rim surface F is minimized to avoid stripping such coating.

Two opposing mold surfaces 101 of side members 61 and 62
and 102 (FIG. 7) are slightly inclined and expand outward at a small angle relative to the radius as shown in FIG. 7 to facilitate removal of the casting P.

The plow can be mounted in other locations as desired, as shown by dash-dotted line 94 (FIG. 13).

These lateral mold members 61 and 62 are, for example, large diameter endless rings of normalized and tempered forged steel.

These members 61 and 62 have total dimensions of 25.4 mm (1 inch) and 38.1 m, as shown in FIG.
m (1.5 inches) in axial length and width).

Another embodiment shown in FIG. 18 is one in which the outer mold side member 61A has a number of deep grooves 103 cut into its outer end a distance of more than half of its axial length and width W).

For pressure relief, the bottom of each groove 103 is perforated to form an enlarged circular termination 104 for each groove.

The grooves are uniformly spaced apart by a distance S, which distance is equal to the width W of member 61A.

The grooved mold side members are more flexible and easier to manipulate.

The inner mold member is a mirror symmetry of that shown in FIG.

A number of guide clamps can be provided on the casting wheel for guiding the mold side members 61.

A mold lateral guide clamp 106 can be provided on the outer periphery of the cylindrical skirt 67-1 in an area proximate to the block 65 and extends radially outwardly and axially, as shown in dashed lines in FIG. The outer surface 1 of the mold side member 61
It is engaged with 07.

In order to cool the casting belt 24, a coolant supply pipe 110 (FIG. 5) is provided which is installed in the cylindrical groove 111 of the inlet pulley 26.

Similarly, a large number of refrigerant nozzle header devices 112 (first, fourth,
7 and 8) extend in an arc (as shown in FIG. 1) near the inner end of the belt 24 (as shown in FIGS. 4 and 7).

Each of these nozzle arrangements 112 is oriented at a slight angle toward the convex outer surface of the belt and includes a number of nozzle orifices 113 (orifices 113) that create a layer of coolant 114 that moves at high speed across the belt for intense cooling of the belt. 7 and 8).

A high-temperature refrigerant device for casting belts as described in U.S. Pat. No. 3,429,363 and U.S. Pat. No. 3,474
It is described in detail in the 853 specification.

What is new is that refrigerant is supplied to the nozzle arrangement 112 from a large cylindrical main supply header 116 that is axially aligned with an axial mounting arrangement 118 to the bub of the rotating wheel 22.

It is usually water containing a corrosion inhibitor.

The refrigerant was connected to refrigerant inlet 122 (FIGS. 3 and 4) (
(not shown) is supplied under pressure from a powerful high-flow pump.

At least one tapered filter 124 of large surface area is inserted into the main liquid supply header to prevent blockage or restriction of the liquid refrigerant through the nozzle by foreign objects introduced simultaneously with the liquid refrigerant supply.

The openings or holes in the sifter 124 are intentionally smaller than the diameters of the various nozzle orifices.

The filter is removably attached to a refrigerant inlet 1220 and a removable lid 127 by a central rod 126.

Refrigerant is supplied from the axial header 116 through a number of holes 128 (FIG. 4) and through generally radial conduits 129 connected to each nozzle arrangement 112.

In order to powerfully and uniformly cool the inner circumference of the cast rim 60, a high-velocity layer 130 of liquid refrigerant is applied onto the inner surface of the rim by a number of rotating refrigerant application nozzle devices 132 mounted within the wheels 22 and rotating with the wheels. be introduced.

5 and 8, the high velocity refrigerant layer 130 is located at the rim 60.
is shown as rapidly moving circumferentially around the inner rim surface in a counterclockwise direction in the same direction as it rotates.

The refrigerant layer 130 moves many times faster than the rim, and the rotating nozzle devices 13 are spaced uniformly circumferentially within the rotating ring 22.
2 indicates whether it can be applied in the same direction or in the opposite direction to the rotation of the rotating wheel.

Two flanges 58 as shown most clearly in FIG.
and 59 are formed by a large flat ring creating a pair of spaced parallel side walls extending around the rotating wheel.

The nozzle device 132 is attached to the rotating wheel side wall 1 by a small screw 133.
It is fixed at a predetermined position between 08 and 109.

A number of refrigerant application nozzle devices 132 periodically apply additional high velocity refrigerant to deposit the high velocity refrigerant layer 130 along the inner circumference of the rim 60 over the entire arcuate extent of the mold cavity C, or as described below. as well as other arcuate areas of the rim.

Associated with each nozzle device 132 is a refrigerant layer 1 extending axially across the wheels and having a refrigerant layer 1 remote from the inner surface of the rim 60.
300 portion is interrupted by a scoop 134.

The interrupted portion of the refrigerant layer is turned and discharged radially inwardly along scoop face 136 as shown by arrow 135.

The diverted refrigerant 135 then flows to each refrigerant discharge trough 138, which has a generally spiral cross-sectional shape to receive the high velocity refrigerant and redirect it axially outward, as shown by arrows 137.

These troughs 138 (FIG. 5) extend outwardly through respective holes 139 (FIGS. 4 and 5) in the side wall 108 of the wheel flange portion 58.

The spent refrigerant is then discharged from the outer end of the gutter 138 and captured by the splash shield collector 51 (not shown).
Return to the large refrigerant supply tank.

As shown in FIGS. 7 and 8, the tip of each scoop 134 extends substantially the entire axial width of the thin rim 60 and the scoop end is spaced a uniform distance from the inner surface of the rim.

For example, in this embodiment of the invention, the spacing between the inner surface of the rim and the tip of the scoop is 4.76 mm (3716 inches).

It can be seen that the surface 140 of each scoop near the rim is arranged at a slightly reducing angle relative to the inner surface of the rim.

Therefore, the converging slope 140 is 4.0 as shown in FIG.
76mm (3/16 inch) to 2.38mm (3/16 inch)
32 inches).

It is also noted that the high velocity refrigerant layer 130 may entrain a small amount of air in the refrigerant convergence passage 140 between the scoop surface and the rim surface.
has been found to improve the operation of the high-velocity film of refrigerant immediately adjacent to the inner surface of the rim.

After a portion 135 of the refrigerant layer is skimmed and the remaining refrigerant film passes through the contraction degassing channel 140, the refrigerant layer 130 is reaccelerated to its previous thickness by the next nozzle 132.

A nozzle assembly 132 is associated with each scoop 134 and extends substantially along side walls 108 and 1 thereof, as shown in FIG.
09 includes a nozzle device 142 extending over the entire axial width of the wheels.

Multiple nozzle orifices 14 provided in each device 142
3 applies refrigerant to the inner surface of the rim 60 at high velocity.

In this embodiment, coolant stream 144 exiting orifice 143 travels along curved surface 145 and impinges at a slight angle toward the inner surface of the rim to spread out and maintain high velocity layer 130 .

Nozzle devices 142 each have a main passageway 146 (FIG. 8) communicating with an orifice 143.

Conduits 147 constituted by flexible high pressure hoses extend generally radially and supply refrigerant to each nozzle arrangement as shown in FIGS. 5 and 8.

Thus, the high velocity refrigerant layer 130 moves circumferentially along the inner surface of the rim 60 and provides a strong cooling effect thereon.

Because of the strong cooling action in the rim 60 and belt 24, the mold elements 60, 24, 61, 62 remain at a temperature close to that of the coolant itself, resulting in several of the advantages outlined at the beginning of this specification.

If desired, a coating can be applied to the casting surface 60 of the rim 60 and to the inner surface of the belt 24 to reduce the rate of cooling applied to the metal being cast.

Since the mold elements 60, 61, 62 and 24 are at substantially uniform and low temperatures, the control effect produced by such a coating is expected to be uniform and the casting P.
(FIG. 13) is effective in producing the desired metallurgical properties.

In order to supply high pressure liquid refrigerant to each nozzle device 132,
Rotary liquid dispensing system 150 (fourth,
5 and 6) are provided.

The bub is mounted on anti-friction bearings 151 and 152 seated on hollow shaft 118.

The axial conduit 153 of the shaft communicates with the forward end of the main axial feed conduit 116 through a hole 154 in the frame 21 .

As shown in FIG.
have.

Liquid distribution system 150 includes a fixed inner gland member 156 (FIG. 6) secured to the outer end of shaft 118 by machine screw 149.

This inner gland member 156 has a capillary conduit 151 that is the same size and aligned with capillary conduit 153 .

A shielding disc 158 is welded across the outer end of conduit 157 and covered by an end cap 159.

Conduit 157 and inner gland member 15 for supplying refrigerant
A number of large radial holes 160 are provided communicating between liquid distribution grooves 1610 around the periphery of 6.

What surrounds the inner gland member 156 is the bubble 12
The outer rotating ground member 162 is attached to

To create a rotating liquid-tight seal between the inner and outer gland members,
A large number of grooves are provided on the outer periphery of the inner gland member installed both inside and outside the groove 161, and these grooves are provided with an O-ring 1.
63 are provided.

Outer gland member 162 is attached to bub 120 by machine screws (not shown) that engage ring mounts 165 at the outer end of the bub.

Also seated in the ring 167 of the bub is a rotary sealing element 16.
6 is provided.

This sealing element 166 engages with the outer circumference of the inner end of the inner gland member 156 near the bearing 151 to protect the bearing.

Outer gland member 162 includes a number of generally radial passageways 168 that communicate with liquid distribution passageways.

Threaded hose fittings 169 are provided within these passageways 168 for supplying refrigerant to the inner ends of hose conduits 147 extending all the way to the nozzle arrangement 132 .

As shown in FIG. 6, these passages 168 have inwardly angled outer ends to provide the most direct flow path to the rotating wheel rim.

If it is desired to cool the entire inner circumference of the rim 60,
The coolant distribution groove 161 is left open over the entire circumference of the inner gland member 156.

If it is desired to apply the high velocity refrigerant 130 (FIG. 8) only to the intended cooling angle portion or portion of the rim 60 that is within the cooling zone, the cooling zone control element 170 (FIGS. 5 and 6) can be inserted into the groove 161 to prevent them from reaching the passages 168 connecting them to the nozzle device 132, which nozzle device 132 is temporarily placed in an uncooled area when the rotating wheel 22 rotates.

The cooling zone control element 170 is connected to the inner gland member groove 161.
is fixed.

Thus, as the outer gland member 162 rotates about the inner gland member as the rotating wheel rotates, the refrigerant is supplied to the continuous unobstructed passage 168 for part of each cycle of rotation. is closed off from the continuous blocked passage 168 to the remainder.

In an apparatus such as that shown in FIG.
It starts at a point near where it is placed.

The rim 60 is therefore strongly cooled by the high velocity layer 130 before and during its access to the metal in which it is cast.

Other control elements 170 of different angular ranges can be used to increase or decrease the angular range of the rim cooling zone.

Area control element 170 is a ring cut out to a desired predetermined angular range, as shown in FIG.

As shown in FIGS. 1, 4 and 5, side walls 108 and 109 of flanges 58 and 59 are connected to spoke webs 172.
are interconnected by.

These spoke webs 172 are joined at their inner ends to a large cylindrical bubble ring 173 having an inner shoulder 174 (FIG. 6), which bubble ring 173 is connected to the bub 12.
It is removably bolted onto the outer shoulder 175 of the 0.

A large circular plate 176C (FIGS. 6 and 7) covers the inside of the rotating wheel.

The spoke webs 112 are uniformly spaced apart and are provided with two radial conduits 147 extending into the rotating wheel between each successive pair of spokes to provide two nozzle arrangements 13 .
2 and troughs 138 are installed between the outer ends of successive pairs of spokes.

In FIG. 5, the outer end of each spoke web 172 terminates at a radially spaced location inwardly from the rim 60 and terminates in the coolant layer 13.
0 (FIG. 8) to provide a large gap on the outside of the end 177 of each spoke to allow it to pass as it moves along the inner circumference of the rim 60.

As shown most clearly in FIG. 15, each flange 58 (and 59) on the rotating wheel has a flat cylindrical outer circumference 118.
so that the thin cylindrical rim 60 can seat properly against this outer periphery of the area extending near the casting area C.
