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1 813-1 893 K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.
In the laboratory, BaO-CaO-CaF2 system slag was used for deep dephosphorization of molten steel to obtain ultra-low phosphorus molten steel.The experimental results show that the dephosphorization rate of more than 50% is obtained with the initial phosphorus content of about 0.01% % Of the lowest 0.002% of the phosphorus content; Dephosphorization effect is significantly affected by the molten steel oxidation experimentally measured within the range of 1 813-1 893 K phosphorus capacity of the slag system between 1018-1019.35, and with increasing BaO content, phosphorus Increased capacity.
