FIELD: manufacture of cast pieces with equiaxial structure by precise casting with use of investment patterns. ^ SUBSTANCE: apparatus includes melting chamber with lids; melting crucible with inductors; mechanism for charging/discharging crucible; induction furnace with heating member for heating mold. Melting crucible has bottom draining and it is provided with stop. Melting crucible, mechanism for moving stop, induction furnace for heating mold and mechanism for moving mold are mounted on one lid and they form melting-casting unit. In one variant of invention lids are made with possibility of motion relative to stationary melting chamber. In other variant of invention melting chamber is made with possibility of motion relative to melting-casting unit. ^ EFFECT: shortened time period for preparing apparatus to melting, simplified design of apparatus. ^ 8 cl, 4 dwg, 1 tbl, 1 ex
