      超低硫钢精炼工艺

      Research on Ultra-low Sulphur Steel Refining Process

      摘要:
      在感应炉上进行了一系列对比实验,研究结果 表明:顶渣+喂线工艺比完全顶渣工艺具有更快的脱硫效果, 含BaO精炼渣系比传 统的CaOsi(100)渣系具有更强的脱硫能力;当钢中氧和硫都 很低时,CaSi合金能起到显著的深脱硫作用.由研究结果得出超低硫钢(wS< 0.0010%)钢液精炼的主要工艺参数
      Abstract:
      A serial of contrast experiments were carried out on induction furnace. It's found that a better desulphurization 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
