BLANK PRODUCTION

Vlasov A. F. — Electroslag casting of the mining equipment components using exothermal conducting fluxes

Experimental methods found that the developed method of fabrication of mining equipment parts electroslag casting method using a solid start and exothermic fluxes, significantly reduces the complexity of their fabrication. For the development of the technology electroslag casting gear tooth and finger bucket designed and manufactured special equipment. Cast on new technology gear and finger bucket had a smooth surface without corrugations, sink marks, slag inclusions. The chemical composition of the metal is melted within its grade composition. Alloyage 40ÕÍ steel alloying elements to steel grade composition 38ÕÃÍ performed with a dispenser.
