| Abstract: | Based on multicomponent regression analysis, the model of prediction for end temperature of molten steel TL in CAS-composition adjustment by sealed argon bubbling refining has been established: TL= t -(-920.64 + 0.0643625X1+0. 187162X2+ 0.581293t +0.003662X3),where X1- molten steel laying aside time /min;X2- refining teated time/min; X3- amount of added alloy /kg; t- temperature of molten steel at beginning of treatment /℃. The re- sults of statistic analysis on prediction temperature showed that the hitting probability of prediction deviation of±5 ℃ and ±10 ℃ was 87% and 95% respectively. |
