Definitions

  • FIG. 2 is a large scale vertical sectional view of a belt-type casting mold in accordance with an embodiment of the instant invention
  • FIG. 5 is a sectional view similar to FIG. 3 but embodying a modification.
  • Sealing means 30 are provided for sealing the tundish 26 in the cavity 28.
  • the molten part of the casting is shown at 31 and the solidified part, the slab, is indicated at 32.
  • Means are provided for pressing the portions 20 and 21' towards the wide surfaces of the solidified slab 32, acting oppositely vertically in FIG. 2. These means comprise two sets of pressure rolls 33. Each set of rolls 33 is associated with one of the belts 20, 21 and is completely surrounded thereby.
  • All the rolls 33 are parallel.
  • the rolls 33 of each set are connected together.
  • Each roll 33 of each set is journalled in a link of a chain, the rolls 33 of the belt 20 being journalled by the links of a chain 34, and the r0115 33 of the belt 21 being journalled by the links of the chain 34a.
  • Each roll 33 may be elastically journalled in two opposite bearings 36 of the respective chain link.
  • the bearings 36 are movable and are actuated by pistons 37 of air pressure cylinders 38.
  • the compressed air is brought to the cylinders 38 through conduits 39.
  • Other pressure media may, however, be used instead, for instance springs or the like, to press the pressure rolls 33 against the wide surfaces of the slab 32.
  • spring means such as compression springs 49 form the pressure means to press the rolls 33 towards the casting 32.
  • the moving belts 20 and 21 will be cooled throughout the portions 20' and 21 by spraying with a coolant, such as water.
  • a coolant such as water.
  • the water is conducted through conduits (not shown) to nozzles 40 that eject the water in fiat sprays.
  • the vertical hand-drawn lines 41 indicate the sprayed cooling water.
  • Means are arranged, indicated at 42, for sucking away the water vapor, and means 43 are arranged to suck away not only the water vapor but also the water.
  • the endless chains 34 and 34a circulate in an opposite direction as the respective surrounding belts 20 and 21, respectively.
  • the belt 20 is indicated as circulating counterclockwise in the direction A
  • the chain 34 surrounded by the belt 20 circulates in the clockwise direction A.
  • the belt 21 that moves clockwise as indicated at B surrounds the endless chain 34a which moves counterclockwise as indicated at B.
  • the portions 20 and 21' and 21 may be pressed towards the slab 32 by fluid streams which strike the portions 20' and 21' at high speed.
  • fluids may be liquid or gaseous fluids.
  • liquid fluids such as water, large amounts are required for spraying requiring, in turn, removal conduits of large diameter.
  • pressurized gaseous fluid may therefore be preferable for this purpose.
  • the compressed air may be used not only to exert pressure onto the belt 20, but also to cool it.
  • water mist may be added to the compressed air for the combined pressurizing and cooling.
  • the compressed air that is used for pressing the belts 20, 21 towards the slab 32 may suflice for the cooling of the slab 32 if the casting operation is carried out sufficiently slowly; for instance, for the casting of an aluminum plate having a thickness of 13 mm.
  • the normal casting speed is from to meters per minute; heavier plates would, of course, need to be cast at a slower speed.
  • the slab 32 continues to cool until it leaves the mold cavity 28.
  • the slab 32 is subjected to pressures applied to its wide surfaces, as shown in FIG. 2 from above and below.
  • This pressure may be exerted either by the pressure rollers 33 that are journalled by links of the chains 34 and 340, which chains circulate oppositely relative to the encircling belts; or the pressure may be exerted by a pressure fluid, such as compressed air.
  • the slab 32 during its movement in the direction D through the cavity 28, will be subjected to a cooling action.
  • a cooling action As previously indicated, where it is desired to pass the slab through a regulating station and thence directly into a synchronized hot rolling mill, it is important that the slab, after having become solidified, avoids the excessive loss of heat.
  • the invention provides furthermore that the pressure exertion by the fluid stream can be alternated with the spraying with a coolant.
  • said pressure means including rolls applied to at least one of said belts near said portion thereof, movable bearing means suspending said rolls, and resilient means connected to said bearing means and pressing the said rolls elastically towards the casting in the mold cavity.
  • said resilient means comprising at least one air pressure cylinder for each roll, a piston in said cylinder and being in driving connection with the bearing means of said roll, said piston being operable by air pressuree for resiliently pressing said roll towards the casting.
  • each chain circulating in opposite direction relative to the circulating direction of its encircling belt.
