摘　　要：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%。Base on the collective drive of high-speed rod-rolling mill,in order to ensure the micro constant tension in rolling,the requirements of continuous rolling tension can be satisfied by matching each roller diameter r for the finishing mill.After the roller diameter of high-speed rod-rolling mill is discrete,the minimum tension between the finishing mills is optimized by the dynamic programming method according to multi-stage decision-making of multiple stages.For rolling the wire of diameter 10 mm,the total tension coefficient dropped about 37% by the optimization of minimum tension.
