Abstract

PURPOSE: To obviate the occurrence of surface cracking by smoothly dropping the ingot surface temp. just under the mold until the rate of solidification of the cast ingot is lowered to a half and regulating the surface temp. at the ingot leveling point to the predetermined temp or more.
CONSTITUTION: From just under the mold until the rate of solidification of the cast ingot is lowered to about a half, the ingot is intensely cooled by smoothing the dropping of the ingot surface temp. The cooling just before the leveling point of the ingot is made slow, to restore the heat and the ingot surface temp. at the ingot leveling point is kept ≥900W950°C.
