摘要
根据青钢第二炼钢厂LF精炼造渣工艺的特点,利用炉渣组元CaO、SiO2、Al2O3、CaF2进行分析探讨,制定出合理的渣系配比和快速造白泡沫渣工艺。实践证明,此工艺可减少化渣、造渣时间各约7 min,钢材中全氧含量可降低10×10-6,脱硫率可提高15%以上,成分和温度控制的精度得到提高,充分发挥了LF的精炼效果。
According to characteristics of-slag-making technology in LF in No.2 Steelmaking Plant of Qingdao Steel, we analyzed and studied the slag components CaO, SiO2, Al2O3 and CaF2, then made a reasonable slag-components rate and a white foamed slag-fast making technology. Practices proved that this technology may reduced the time of slag-making about 7 minutes, the entire oxygen content may reduced 10 × 10^-6 in the steel products, the desulfurization rate may enhanced above 15%, the precision of ingredient and temperature controlling may enhanced, fully displayed the refining effect in LF.
