摘要：

The multicomponent slagging behavior and mapping relationship of SiO2, Fe, S, Cu and CaO and slag constitution optimization were investigated by analyzing SiO2, Fe, S, CaO and Cu content variation trends of industrial iron silicate slag in copper oxygen bottom blowing bath smelting (BBS) process, combined with metallurgical process principles. The results show that the slagging behaviors of SiO2, Fe, S, Cu and CaO have certain correlation, and the correlation sequence with Cu slagging behavior is S, m (Fe) /m (SiO2), SiO2, Fe. The rule of coupling interaction between SiO2 and Fe to Cu is sensible. Cu content increases with the increase of SiO2 and the decrease of Fe. Through optimizing the slag, SiO2 and Fe contents in slag are 26.5%-28% and 38.5%-40% (mass fraction), respectively. The slag has good fluidity, Cu content of BBS slag is lower than 2.5% in theory. ©, 2015, Zhongguo Youse Jinshu Xuebao/Chinese Journal of Nonferrous Metals. All right reserved.
