摘　　要：实验室内用模型复吹转炉研究了含Na_2CO_3、CaO等混合脱磷剂炉内脱磷效果及若干工艺因素的影响,试验证明,吨钢Na_2CO_3用量3～5kg可使中、低碳钢液磷含量降至<0.010％。工业试验证明,适当条件下复吹转炉中吨钢Na_2CO_3用量2.5kg(不加其它材料)可使磷降至<0.010％。The dephosphorization effect of flux containing Na_2CO_3, CaO etc. in converter and the influe-nce of some affecting factors have been studied in a converter model. It is shown that the P content of liquid steel with midium or low carbon may be easily reduced to<0.010% by using 3～ 5 kg Na_2CO_3/t. Trials in a commercial combind blowing converter show that the P content of liquid steel can be brought to<0.010% by using 2.5 kg Na_2CO_3/t (without addition of other materials) under proper conditions.
