INVESTIGATION OF MECHANICAL CHARACTERISTICS AND STRUCTURE OF CAST STAMP STEELS FOR COATINGS OF TECHNOLOGICAL AUXILIARIES, RESTORED BY MEANS OF ELECTROSLAG HEATING

Abstract

The results of investigations of mechanical characteristics and structures of steels for the technological accessory, recovered by means of electroslag technologies, which are economically efficient ways of stamps recovery are presented. The contents of nonmetallic impurities in metal after electroslag heating is considerably reduced, the impurities are becoming more dispersed and are distributed in ingot volume more uniformly. The characteristics of plasticity and viscosity after electroslag heating are practically equivalent to these characteristics for deformed metal and cost of the stamp recovered by means of electroslag heating is considerably lower than the cost of accessory of deformed metal.
