Research on Ultra-low Sulphur Steel Refining Process
-
摘要: 在感應爐上進行了一系列對比實驗,研究結果表明:頂渣+喂線工藝比完全頂渣工藝具有更快的脫硫效果,含BaO精煉渣系比傳統的CaO-CaF2渣系具有更強的脫硫能力;當鋼中氧和硫都很低時,CaSi合金能起到顯著的深脫硫作用.由研究結果得出超低硫鋼(ws<0.0010%)鋼液精煉的主要工藝參數.Abstract: A serial of contrast experiments were carried out on induction furnace. It's found that a betterdesulphurization result exists in the top slag plus sire injection Process than in the single top slag process. Slag which contains BaO has stronger desulphurization ability than that does not. CaSi alloy can decrease the terminal sulphur content in the steel when[O] and[S] are low Further, some basic technological parameters were proposed for the refining of ultra-low sulphur steel.
