转炉少渣吹炼铬矿直接合金化基础研究

FUNDAMENTAL STUDIES ON DIRECT ALLOYING USING CHROMIUM ORE IN LESS SLAG BLOWING AT BOF

通过平衡实验和模拟实验 ,探明了复吹转炉利用预处理铁水少渣吹炼 ,铬矿直接合金化时 ,铬的还原速度与渣成分、温度、搅拌以及矿粒度、加入方式等的关系。

Investigation has been carried out on effect of slag composition,bath temperature,Ar stirring and ore size on reduction speed by balance calculation and hot simulation experiment.The reduction of chromite is discussed theoretically.
