1　影响泡沫渣的主要因素新疆钢厂 40 0炉的实践证明 ,当炉渣碱度为2 .0时 ,泡沫渣高度最大 (图 1 ) ;泡沫渣发泡高度随吹氧量的增加而增加 ,渣中ＦｅＯ为 2 0 %左右 ,泡沫渣高度可达最大值 (图 2 ) ,这与文献 [1 ]的结果相一致。图 1　炉渣碱度对发泡高度的影响Ｆｉｇ .1　Ｅ 1 The main factors affecting the foam slag 40 steel furnace in Xinjiang Steel Practice proved that when the slag basicity of 2.0, the maximum height of foam slag (Figure 1); foaming slag foam height increases with the increase of oxygen blowing, Slag FeO is about 20%, foam slag height up to the maximum (Figure 2), which is consistent with the results of the literature [1].
