一热轧和二热轧机组精轧数模剖析

分析了宝钢一、二热轧精轧轧制力计算模型，并与轧制力计算模型的一般形式进行了比较。结果表明一热轧模型的结构较差，容易产生预测误差并引起辊缝设定误差。二热轧精轧轧制力计算模型的结构好，适用性强，也便于移植。

Analysis on the Finishing Mill Models of Nos.1 & 2 Hot Rolling Mills in Bao Steel

The rolling force prediction models for the 1st & 2nd hot rolling mills in Bao Steel are analysed and compared with the general form of the force prediction model.It is pointed out that the model employed in the 1st mill is ill structured,easier to cause prediction errors,and consequently cause error in roll gap set up;and the model for the 2nd is of well structure,better adaptability and convenient to be transplanted.
