摘要
采用多元回归分析建立了 30 0tCAS精炼 (密封吹氩调整成分 )终点钢水温度 T钢包 ℃的预测模型 :T钢包 =t - (- 92 0 6 4 +0 .0 6 4 36 2 5x1 +0 .18716 2x2 +0 .5 812 93t +0 .0 0 36 6 2x3) ,式中x1 钢水搁置时间 min ;x2 精炼处理时间 min ;x3 合金加入量 kg ,t 处理开始钢水温度 ℃。对预测温度统计分析结果表明 ,该模型对CAS精炼终点温度的预测误差在± 5℃和± 10℃时的命中率分别为 87%和 95 %。
Based on multicomponent regression analysis, the model of prediction for end temperature of molten steel - T L in CAS- composition adjustment by sealed argon bubbling refining has been established: T L = t -(-920.64 + 0.064 362 5 x 1 + 0.187 162 x 2 + 0.581 29 3 t + 0.003 662 x 3), where x 1- molten steel laying aside time /min; x 2- refining treated time/min; x 3- amount of added alloy /kg; t- temperature of molten steel at beginning of treatment /℃. The results of statistic analysis on prediction temperature showed that the hitting probability of prediction deviation of ±5 ℃ and ±10 ℃ was 87% and 95% respectively.
