FIELD: technological processes.
SUBSTANCE: invention relates to the foundry. Profitable part of steel billet is formed in rotating metal mold and steel melt is poured into metal mold. After pouring, the bottom part is covered with an exothermic mixture and covered with material with low heat conductivity. Material with low heat conductivity is used to form a profitable part.
EFFECT: enabling increase in the metal utilization factor due to exclusion of shrinkage defects in the workpiece.
