摘　　要：对含磷量为０．２％～０．１６％的铸造生铁进行了脱磷试验。采用氧化法脱磷的平均脱磷率可达７０％左右，含磷量可以降低到 ０．０１％以下。试验表明，只有将铸铁含硅量降至较低水平，才能有效地进行脱磷。An experiment on dephosphororization of foundry pig iron containing 0. 12% -- 0. 16% of phosphorus was carried out. When using oxidizing process,the average dephosphorizing rate had been up to about 70%. The phosphorus content could be reduced to less than 0.01%. The experiment showed that only when the silicon content has been reduced to a relatively low level it is possible to dephosphorize effectively.
