Abstract

Based on multicomponent regression analysis

the model of prediction for end temperature of molten steel T

in CAS-composition adjustment by sealed argon bubbling refining has been established: T

= t -(-920.64 + 0.0643625X

+0. 187162X

+ 0.581293t +0.003662X

)

where X

- molten steel laying aside time /min;X

- refining teated time/min; X

- 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.
