电弧炉内不锈钢BaCO_3-BaCl_2渣脱磷试验研究

INVESTIGATION ON DEPHOSPHORIZATION OF STAINLESS STEEL IN EAF WITH BaCO 3 BaCl 2 FLUX

试验研究了１０ｔ电弧炉内用ＢａＣＯ３－ＢａＣｌ２渣对不锈钢进行氧化脱磷的效果及其影响因素。结果表明，当渣量为８０～１００ｋｇ／ｔ时，可获得２０％～５０％的脱磷率；当渣量为１６０～２００ｋｇ／ｔ时，可获得４２％～６８％的脱磷率。电弧炉内不锈钢氧化脱磷的最佳条件是：［Ｃ］ｉ＝０．８０％～１．２０％，［Ｓｉ］ｉ≤０．１５％～０．２０％，温度为１５５０～１６２０℃。

Experiments were carried out to investigate dephosphorization of stainless steel in EAF with BaCO 3 BaCl 2 flux Results revealed that,when the flux amount is 80～100 kg/t,the dephosphorization rate is 20 %～50 %;when the flux amount is 160～200 kg/t,the dephosphorization rate is 42 %～68 % The suitable process conditions in EAF are expressed as following: i=0 80 %～1 20 %, i≤0 15 %～0 20 %,t=1 550～1 620 ℃。
