| 摘 要： | K-OBM-S转炉是以铁水和电弧炉预熔钢液为原料冶炼不锈钢的精炼设备。以转炉冶炼普碳钢的顶吹模型和AOD法冶炼不锈钢模型为基础,建立了适用于80 t K-OBM-S转炉冶炼不锈钢的数学模型。对二步法冶炼2Cr13型不锈钢和三步法冶炼0Cr18Ni9型不锈钢的过程验证结果表明,大部分终点碳含量的误差≤±0.03%,终点铬含量误差≤±0.3%,110炉0Cr18Ni9钢目标碳(0.10%～0.25%)命中率为95.6%,终点目标铬(17.1%17.6%)的命中率为85.2%。

| Abstract: | K-OBM-S converter is a refining unit for steelmaking of stainless steel by charging hot metal and EAF premelting molten steel* Based on model of top-blown oxygen in converter for plain carbon steel melting and model of AOD process for stainless steel melting, a mathematical modeling of a 80 t K-OBM-S converter for steelmaking of stainless steel has been established. The verified results of steelmaking 2Crl3 stainless steel by duplex route and steelmaking 0Crl8Ni9 stainless steel by triplex route showed that the error of endrpoint carbon was mostly w ±0.03% and the error cf end-point chromium was ≤±0.3%, the percentage of hits for end-point aim caihon (0.10% - 0.25%) for 110 heats 0Crl8Ni9 steel was 95.6% and for end-point chromium (17.1% ~ 17.6%) was 85.2% |
