Definitions

  • FIG. 7 is a graph illustrating the relationship between the heat-transfer characteristics of a prior art casting wheel and of that embodiment of the invention shown in FIGS. 1 and 5.
  • the manifolds 21 and 21' are so positioned that all sides of metal C are cooled and each manifold 21 21' can be independently controlled through valves V1, V2, V3 and V4 to selectively control the cooling rate of each side of metal C.
  • the cooling fluid is discharged on metal C through a plurality of conventional nozzles 35.
  • an alternate embodiment of the invention which includes casting wheel 40, flexible band 41, and band support wheels 42, 44, and 45.
  • Pouring pot 46 is arranged to pour molten metal into the peripheral groove of casting wheel 40.
  • the arrangement of casting wheel 40, band supports wheels 42-45 and pouring pot 46 is similar to the arrangement of FIG. 1; however, the extended cooling section 18 of FIG. I is replaced by water spray manifold 48, and the cast bar C is allowed to remain in the casting wheel until it is extracted therefrom at the conventional position.
  • Water spray manifold 48 is arcuate and extends around the casting wheel from the position where band 41 is removed from the peripheral groove of the casting wheel by support wheel 45, to the point of extraction of the cast bar C.
  • This crust continues to thicken during the second solidification phase and the rotational speed of the casting wheel is such that by the time the metal has reached the end of phase 2, the crust enclosing the molten center is sufficiently thick to support the molten center without collapsing.
  • the solidification phases of a metal being cast by the invention are illustrated schematically, showing that the metal is removed from the casting wheel 10 when the forming of the outer crust has reached that point at which the metal has shrunk and drawn away from the mold M. This point is or near the start of the third solidification phase and metal C still has a liquid core as indicated in FIG. 4 when it is discharged from the casting wheel 10.
  • any conventional coolant may be passed over metal C to complete the solidification thereof at a much faster rate of heat transfer than any rate possible in the third phase in the conventional casting wheel 10' illustrated in FIG. 3.
  • the rate of heat transfer or cooling in the third phase of solidification by the invention relative cooling in the mold M can be best seen by referring to FIG. 7 wherein the solid line indicates that the rate of heat transfer by the invention in the third phase is much higher than that of a conventional casting wheel 10' as shown by the dashed line.
  • the invention requires the operation of the casting machine C at a rotational speed which will result in the metal passing to the cooling section 18 at the beginning of or early in the third solidification phase. It will also be understood that this requirement provides greater casting rates than were possible with prior art casting wheels.
  • the cooling section 18 sprays a coolant onto metal C, other types of cooling may be utilized such as passing metal C through a tank filled with a coolant to cool the metal C.
