【摘要】 对精炼炉熔渣的泡沫化进行了实验室研究和半工业性的实验研究。实验在硅化钼棒炉和 10 0 0 kg感应炉内进行。考察了熔渣碱度、熔渣中 Ca F2 含量及发泡剂配比对发泡效果的影响。在分析大量实验数据的基础上 ,对熔渣发泡机理进行了探讨。研究结果表明 :所研究的 Ca O- Si O2 -Mg O- Al2 O3渣系 ,在碱度为 1.0～ 1.2、Ca F2 含量为 6 %～ 8%和碳加入量过剩指数为 1.4～ 1.5时 ,发泡效果较好。更多还原

【Abstract】 The experimental work on foaming behavior of refinign slag in LF ladle was carried out by the uprigh type furnace and 1 000 kg induction furnace. The effects of refining slag basicity, CaF 2 content and the composition of the foamer on foaming rate and foaming index were studied. The mechanism of slag foaming was analysied theoretically.更多还原
