中文摘要：
为使含钛高炉渣中的钛组分富集于钙钛矿相中，基于选择性析出技术，需要对炉渣进行氧化处理．用淬火法研究了氧化处理后含钛高炉渣非等温过程钙钛矿相的结晶行为，并讨论了其析出动力学规律．实验结果表明，钙钛矿相的析出与冷却速度有关．冷却速度小，钙钛矿相的析出量大．钙钛矿相的析出动力学过程可近似用JMAK经验方程描述．
英文摘要：
In order to promote the enrichment of titanium component in perovskite phase, based on the technology of selective precipitation, the slag is supposed to be oxidized. In this work, the non-isothermal precipitating behavior of perovskite phase in oxidized titanium bearing slag was studied by quenching method, and the precipitating process kinetics of perovskite phase was analyzed. The results show that the precipitating of perovskite phase is related to the cooling rate, i.e. the lower the cooling rate, the higher the volume fraction of perovskite phase. The precipitation kinetics of perovskite phase can be approximately described by the JMAK equation.
