抄録

Submerged arc welding fluxes are analogous to steelmaking slags The fundamental slag component consists of FeO-Fe₂O₃ CaO-SiO₂ system. But the temperature of welding is higher than that of steelmaking and the time of reaction is short in welding. Author has studied equilibrium of gas-slag-metal over an extensive change of temperature in the welding from the statistical ther-modynamical method which was reported previously on the theory of steelmakig.<BR>In this report, author has established equilibrium equations among oxygen atmosphere, molten slag FeO-Fe₂O₃ CaO-SiO₂ and molten iron Fe-Si-O, and examined the physical constant values.<BR>Author could explain the reduction values of silicon and the quantity of oxygen in molten iron for solving the equation by this method, though he was unable to explain this point by the chemical method that had been hitherto used.<BR>The results of calculation will be reported next time.
