of dephosphorization in a converter was thus established through a combination of these two aspects. The composition of the initial slag was considered to be approximately 15wt%CaO –44wt%SiO 2–41wt%FeO. During...Slag formation path during dephosphorization process in a converterJiang Diao,Yong Qiao,Xuan Liu,Xie Zhang,Xin Qiu,Bing XieCollege of Materials Science and Engineering, Chongqing University摘 要:
