| 摘 要： | 通过加入以Ca-Fe合金为基础的脱砷剂对钢水进行了一系列脱砷实验研究. 结果表明，随钢中O含量降低脱砷率逐渐升高，当钢中O含量为1.0695′10-4(w)时，脱砷率达到37.5%；脱砷率随Ca-Fe合金加入量增加而增大，当Ca-Fe合金加入量为试样质量的18%时，脱砷率达50%；钢中原始砷含量越高，脱砷率越大，当原始砷含量为8.00′10-4(w)时，脱砷率高达77.5%；Ca-Fe合金与添加剂共同作用更有利于砷的去除，脱砷率最高达到81%.

| Abstract: | Dearsenication by adding Ca-Fe alloy-based arsenic removal agent in molten steel was studied.The effects of oxygen content in the steel,Ca-Fe alloy adding amount and initial arsenic content in the steel on the removal process were investigated.The results showed that the removal rate of arsenic increased with the oxygen content in the steel treated.When the oxygen content was 1.0695'10-4(w),the removal rate was 37.5%.The removal rate increased gradually with increasing of Ca-Fe alloy adding amount.When the ... |
