Abstract
FIELD: foundry. SUBSTANCE: method of making shutter for casting ladle make of fire resistant refractory concrete comprises steps of inserting ring 9 of preliminarily made refractory concrete to casting mold 1 in such a way that said ring concentrically embraces pouring duct 6; filling casting mold by paste-like refractory concrete 4, compacting filled mass, drying it and impregnating under pressure. Then carrier carbon embedded into sealing surface of shutter for casting ladle is burnt out at heat treatment in reduction atmosphere with carbon separation. If it is necessary one of several cycles of vacuum heat treatment may be used. Due to insertion of preliminarily make ring 9 and realization of above mentioned steps sliding surface of shutter for casting ladle exhibits super high service properties. Said preliminarily made ring may simultaneously compensate increased loads in zone of pouring duct. EFFECT: enhanced consumer's properties, increased service life period of shutter.
