摘　　要：根据CaO基熔渣和钢液之间在 185 3K脱磷平衡实验结果 ,利用CaO Fe2 O3 CaF2 和CaO BaO Fe2 O3 CaF2 熔剂对钢液进行二次精炼脱磷试验 ,试验发现 ,采用优化组成的CaO基熔剂 ,可得到大于 90 %的脱磷率 ,能将钢液磷含量从 0 .0 5 %降低到 0 .0 0 5 %以下。Based on test results of dephosphorization equilibria between CaO based slags and liquid steel, the experiments of dephosphorization of liquid steel during secondary refining by flux CaO\|Fe\-2O\-3\|CaF\-2 and CaO\|BaO\|Fe\-2O\-3\|CaF\-2 have been carried out, and it is found that the dephosphorization ratio could be more than 90% as using optimum ingredient CaO based fluxes during secondary refining i.e. the phosphorus content in steel could be decreased to less than 0 005% from 0 05%.
