CASTINGS IN CHILL CASTING MACHINE PRODUCING METHOD AND CHILL CASTING MACHINE FOR PERFORMING THE SAME Russian patent published in 2006 - IPC B22D15/00 

FIELD: foundry.

SUBSTANCE: method comprises steps of assembling chill mold at placing core; pouring metal into chill mold; cooling metal; using core in the form of heat pipe. On outer surface of cooling zone there is thread cut by depth h =(0.15 - 0.3)δ where δ - wall thickness of core. After pouring melt metal to chill mold, heating zone of heat pipe is heated up. When temperature of cooling zone achieves value t₀ = (0.9 - 2)t _boil where t _boil - boiling temperature of heat transfer agent in core, core is cooled by means of water-air mixture at water content 2 - 5 mass %.

EFFECT: enhanced efficiency of metal cooling in chill mold, possibility for controlling surface quality and inner structure of blanks of different metals.
