Abstract With the actual production of Non-oriented Silicon Steel,the source of sulphur and the metallugic parameters like slag character , temperature and bottom stirring have been analyzed.The results show that the main source of steel is molten metal,scrap, the remaining slag volume in hot metal and lime； For advanc effect of desulphurization when smelt Silicon Steel, metallugic parameters are controled as follow：end slag R: 3.0～3.5, （FeO）≤20%，end temperature≥1680℃ and enhance bottom stirring. The ave [S] is 0.0048%，whtch can satisfy Non-oriented Silicon Steel.
