In order to control the rolling force, we must build the mathematic model of rolling force.
为了控制铸轧力，必须建立铸轧力控制数学模型。
The models can be used to predict strip surface roughness, arrange steel strip rolling order reasonably, decide the time of work roll off mill and modify the calculation model of rolling force.
这些模型可以用于生产中预测轧后带钢表面粗糙度、合理安排带钢轧制顺序、决定工作辊下机时间和修正轧制力计算模型。
The result of on-line application indicated that rolling force model has good precision of prediction with an error less than 5%.
