FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Lost head is composed of a cavity in casting mould. Said cavity houses heat-insulation shell with vertical seats. The latter are located within the outer outline of lost head and filled with exothermal mix.
EFFECT: higher quality of casts and yield, simplified fabrication of lost head.
