摘　　要：针对采用含钒铁水生产无取向电工钢存在的铁水脱硫率低、转炉冶炼过程回硫量大、成品硫含量偏高的问题,通过对含钒钛铁水脱硫,减少转炉冶炼过程回硫以及RH脱硫技术等方面的研究,大幅度降低了电工钢成品硫含量。生产表明钢中w(S)=0.001 9%～0.006 9%,平均为0.004 2%;w(S)≤0.008%的比例达到了100%,且w(S)≤0.005%的比例也达到了91.43%。In cognizance of the problems of low desulphurization rate for hot metal, large sulfurrecovery in converter as well as high sulfur content inproducts in producing non-orientation electrical steel with vanadiumcontent hot metal countermeasures have been carried out. Sulfur content in non-orientation electrical steel is decreased obviously by way of study on technologies of desulphurization for hot metal with vanadium ＆ titanium, sulfurrecovery control in converter and desulphurization in RH refining process as well. The results of industrial testsshow that w（S）=0.001 9 %~0.006 9 %, and 0.004 2 %is average, the rate w（S）≤0.008 % is as high as 100 %, and the rate w（S）≤0.005 % reaches 91.43 %.
