| 摘 要： | 使用BaO-CaO-CaF2系渣在实验室中进行钢水深脱磷实验以获得超低磷钢水.实验结果表明,初始磷约为0.01%的条件下,获得了50%以上的脱磷率及0.005%以下最低0.002%的磷含量;脱磷效果受钢水氧化性影响显著.实验测得1 813～1 893K范围内该渣系的磷容量在1018～1019.35之间,并且随BaO含量增加,磷容量增大.

| Abstract: | Deep dephosphorization experiment was carried out in the laboratory by BaO-CaO-CaF2 flux to obtain ultra-low phosphorus steel. The result showed that the P content of the tested steel could decrease from about 0.01% to 0.005% or even lower to 0.002% with a dephosphorization ratio of 50% by use of this kind of flux. It is found that the oxidizability of steel has significant effect on dephosphoriztion when using the BaO-CaO-CaF2 flux. The phosphate capacity of the used system varied from 1018 to 1019.35 in 1 813-1 893 K and increased with the increasing of BaO content. |
