摘要
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 1 573 K. Measurements were also conducted on the FexO activities at temperatures between 1 542 K and 1 604 K by virtue of an electrochemical technique. By using the present experimental results, phosphorus distribution ratios were estimated.
