An effective means for improvement of technical and economic indicators of EAF DC are graphitized cored electrodes, designed at the E.O. Paton Electric Welding Institute. The research works of the first stage, carried out in the industrial furnaces of the type EAF DC-12, showed that the arc of the cored electrode is always maintained in the center of the electrode, a stable electric mode of melting...
Purpose: The main task of this work was the developing of new compositions of the ESR slag that would keep the required amount of easily oxidizable elements in the superalloys and have the favourable physicochemical properties. Design/methodology/approach: Thermo-dynamic modeling was applied to estimate of oxidation effect of the slags on the Inconel 718 superalloy. Slag properties (viscosity, electrical...
