采用多元回归分析建立了60t中间罐内钢水温度-T中间罐／℃的预测模型:T中间罐=-66．7499+ 1．03196T-0．768236x1—0．00750014x2+0．232252t-0．606243t2-9．39124×10-6t3式中:T代表钢包到达回转台时钢水温度(℃);x1代表钢包浇注前搁置时间(min);x2代表中间罐烘烤时间(min);t代表钢包钢水浇注时间(min)。对中间罐内预测温度统计分析结果表明,该模型的钢水温度预测值与实测值非常吻合。
Multiple regression analysis was used to establish a prediction model for the temperature of the molten steel in the 60t intermediate tank: -T tundish / ° C: T tank = -66.7499 + 1.03196T-0.768236x1-0.00750014x2 + 0.232252t-0.606243t2 -9.39124 × 10-6t3 Where: T represents the molten steel temperature (℃) when the ladle arrives at the turntable; x1 represents the ladle time (min) before ladle pouring; x2 represents the intermediate can baking time (min); t represents the ladle Molten steel pouring time (min). The statistical analysis of the predicted temperature in the intermediate tank shows that the predictions of the molten steel temperature in this model are in good agreement with the measured values.
