Beschreibung
Zusammenfassung:	FIELD: production of cast products. ^ SUBSTANCE: method comprises steps of heating casting mold in furnace till temperature exceeding liquids temperature of castings; pouring melt from crucible at least into one intermediate cavity whose volume is no less than that of cast piece; continuously filling cavity restricting cast piece from said intermediate cavity at least through one capillary; displacing casting mold with melt from furnace to cooling zone. Cavity restricting cast piece is filled with possibility of providing melt level over crystallization front in range no less than thickness of cast piece. ^ EFFECT: less loss of yield, possibility for producing cast pieces with normalized crystalline structure, lowered force action of melt upon walls of ceramic mold, laminar melt flow for filling cavity of casting mold. ^ 7 cl, 4 dwg
