摘　　要：该文介绍了一种解决轧制系统负荷不平衡的控制方法。针对莱钢1500mm宽带粗轧主机上下辊电机电流差值过大的现象，采用SIMADYND32位全数字矢量控制交交变频调速系统，在STRUCG程序中建立了负荷平衡控制模型，实现了负荷平衡控制功能。该控制方法的应用，使系统运行稳定可靠，控制精度高，速度响应快，能更好地满足生产工艺的要求。The paper introduces a control method to solve the load imbalance of rolling system. Aiming at the overlarge current difference between the upper and lower roll＇s motors of the 1500mm widestrip roughing main mill in Laiwu Steel, the load balancing process control model is set up in the STRUC G program by adopting the AC-AC frequency conversion speed control system of SIMADYN D 32-bit full-digital vector control to implement the load balancing control functions. The application of the control method makes the system stable and reliable, high control precision, fast response speed, and the system can better meet the requirements of the productive technology.
