高速线材精轧机由于采用集体传动,为保证微恒张力轧制,可以利用匹配各架轧机的轧辊直径的方法满足连轧张力的要求。采用动态规划法,对高速线材精轧机组的轧辊直径进行离散后,按照多阶段过程的决策,进行机架间的最小张力优化。对轧制10mm的线材,通过最小张力优化,使机架间的总张力系数下降约37%。 High-speed wire rod finishing mill due to the use of collective transmission, in order to ensure the micro-constant tension rolling, you can use each mill roll diameter to meet the requirements of the rolling tension. The dynamic programming method is used to optimize the minimum tension among the racks according to the decision of multi-stage process after the roll diameter of high speed wire rod finishing mill is discretized. For rolled 10mm wire, the total tension coefficient between the frames is reduced by about 37% through minimum tension optimization.
