Oxidization mechanism in CaO-FeOx-SiO2 slag with high iron content ZHANG Lin-nan(张林楠), ZHANG Li(张 力), WANG Ming-yu(王明玉), SUI Zhi-tong(隋智通) (School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China) Abstract: Oxidization mechanism in CaO-FeOx-SiO2 slag with high iron content was investigated by blowing oxygen into molten slag so as to oxidize Fe......
in perovskite phase. The addition of CaO and Fe 2O 3 in the slag can increase the precipitation temperature of perovskite phase and observably decrease those of titanium rich diopside and titanium diopside, which is in favor of the precipitation of perovskite phase. Under proper heat treatment condition, about eighty percent of titanium in the slag enrichs in perovskite phase and its average crystal size......
