抄録: | In steelmaking processes, there are incentives to reduce slag volume and CaO consumption. The key to meet these requirements is the better understanding of CaO dissolution mechanism into molten slag, which relies on the knowledge of the thermochemical properties of slags and fluxes used for dephosphorization. In this study, the liquidus compositions coexisted with solid CaO and Ca₂SiO₄-Ca₃P₂O₈ solid solution simultaneously were determined in the quaternary system CaO-SiO₂-P₂O₅-FeₓO at 1573 K. Measurements were also conducted on the FeₓO activities at temperatures between 1542 K and 1604 K by virtue of an electrochemical technique. By using the present experimental results, phosphorus distribution ratios were estimated. |
