FIELD: process engineering.
SUBSTANCE: invention relates to foundry. Proposed method comprises steel casting through lightweight chamotte arranged at ingot mold bottom and representing a hollows tetrahedral truncated bottomless pyramid furnished with casting hole. Pyramid outer size equals inner part of lost head extension. Graphite-based antistick coating is applied onto pyramid inner surface, graphite-to-clay ration being as follows: graphite - 85%, clay - 15%.
EFFECT: higher quality and yield of suitable metal.
