Abstract
Applicability of equilibrium thermodynamic laws for analysis of physico-chemical reactions was established proceeding from analysis of temperature-time conditions of melting of welding fluxes in arc and open gas furnaces. Thermodynamic analysis of reactions of charge components used in welding flux manufacture was conducted. Techniques to control the process of slag melt refining are determined.
Keywords: fused welding fluxes, slag melt, sulphur, phosphorus, thermodynamic analysis
