| 摘 要： | 结合生产中LF渣的典型成分,对LF渣返回利用时的脱硫性能及其影响因素进行了研究,探讨了炉渣的初始w(S)、w(Al2O3),钢水的初始w(S)变化对脱硫的影响.实验结果表明,钢水w(Als)=0.025 %～0.033 %时,采用模拟的LF返回精炼渣,可以实现对钢水的脱硫.在炉渣初始w(S)＞0.61 %时,随渣中硫含量的增大,脱硫率快速下降,w(Al2O3)＜25 %时对脱硫的影响不大.在实际应用中,采用精炼终渣部分返回的模式,可以保证LF精炼的脱硫要求.

| Abstract: | Based on the analysis of the typical compositions of LF slag,recycling use of the LF slag for desulphurization is studied.The influence of initial(S) content,initial S] content,as well as initial(Al2O3)on desulphurization is discussed and verified with test.It is found that desulphurization is possible with the recycled LF slag when dissolved at the level of 0.025 %-0.033 %.The desulphurization rate will decrease distinctly due to the the increase of sulphur content in the carry-over slag when initial(S) i... |
