连铸钢水快速精炼工艺实践

Fast refining process of continuous casting liquid steel

    摘要
  • 摘要: 通过在吹Ar合金微调站加入Al脱氧和SiCa对夹杂物变性,选择合适的造渣剂CaO-SiO2-CaC2以及软吹Ar工艺,可以在不影响连铸机匹配的条件下(18min内)使钢水中活度氧降低到20×10-6以下,渣中的FeO+MnO<3%,而连铸浇注时不会发生水口堵塞现象.满足了马鞍山钢铁公司第三钢轧总厂从美国新引进的使用油润滑浇铸的小异形坯连铸机对钢水质量和生产匹配的要求.

     

    Abstract: Liquid steel for continuous casting was refined quickly at the alloy conditioning station in Masteel with the mixture of CaO-SiO2-CaC2 to slag and Al, SiCa to deoxidize in the period of 18 min (converter match to cast). The activity of oxygen in liquid steel can be decreased less than 20×10-6 and FeO+MnO<3% in the final slag, which meets the needs of shaped block cast machine that lubricates with oil.
