Mass transfer model under electroslag remelting with sheelite and carbon as components of synthetic flux

For Сb 08G2С steel alloying with tungstate electroslag remelting and weld deposition were used. To reduct tungstate calcium we used a schee lite concentrate containing approximately 43 % of tungstate and carbon. The basic characteristics of remelting and slag were investigated by a number of the physicochemical methods: DTA, X-ray analysis, spectral analysis. For some tungstate systems apparent activation energy under carbide diffusion in carbide phase based on DTA and chemical analysis data was estimated.
