APPARATUS FOR PRODUCTION OF CASTINGS BY DIRECTED CRYSTALLIZATION Russian patent published in 1997 - IPC

FIELD: apparatuses for production of castings in ceramic shell moulds by directed crystallization. SUBSTANCE: aim is to create conditions for simultaneous realization of all process operations. To realize the aim means for mounting and fixation of casting moulds are mounted on lifting-turning table. Together with in series mounted vacuumized body and embracing it smelting inductor and inductors for moulds head part heating they are forming positions of casting and crystallization of moulds. Position of loading-unloading is located between them. Vacuum system of body and inductors are interlocked with lifting-turning table mechanism for synchronous putting inductors and vacuum system into operation. Table turning by one position is exercised as table is in lower location. Then table is lifted and all required operations are carried out simultaneously. Then table is lowered and the cycle is repeated again. Number of crystallization is determined according to time of its realization. EFFECT: created conditions for simultaneous realization of all process operations. 2 cl
