| 摘 要： | 介绍了一种在线使用的冷连轧机负荷分配方法:通过查询数据库得到初始的负荷分配模式和负荷分配比,利用该负荷分配模式建立单目标负荷目标函数;采用简化的Newton Raphson法迭代求解非线性方程组,得到负荷分配的初始结果;根据第5机架轧制带钢长度对负荷分配结果进行修正,以克服轧制过程中带钢打滑现象;对负荷分配结果进行极限值的检查修正并最终确定负荷分配结果。该负荷分配方法用于在线,有较好的使用效果。

| Abstract: | A load distribution method of on line process control on tandem cold rolling mill is introduced. The initial load distribution mode and ratio are queried from database, and a single object distribution function is built. Using simplified Newton-Raphson method, the nonlinear equations can be solved to get load distribution. Then according to the rolled strip length on the No. 5 stand, the correction of load distribution is carried out, in order to avoid the slip of strip. The limitation of correction will be checked and be corrected if over-limit is occurred, then the final load distribution can be got. This method has been used on line with good effect. |
