摘　　要： 提出了两阶段楔形板轧制的观点,并建立了楔形轧制的过程控制模型;运用负荷函数法结合循环迭代法进行了楔形轧制道次数及中间厚度的优化确定;在不改变楔形轧制优化的道次数的前提下,进行了楔形轧制阶段各道次的压下量优化重分配,优化了轧制规程。模拟仿真表明,该过程控制模型能够根据各种坯料规格及目标尺寸规格,很好地优化制定楔形轧制过程控制规程,可以为楔形板的实际生产提供一定的参考依据。 Dividing the rolling process of longitudinal profile （LP） plate into two rolling phases was put forward. Load function method and circular iterative method were combined together to optimize the pass number and middle gauge of LP rolling. Draft of passes of LP rolling phase was optimized without changing the pass number, and so that the rolling schedule was optimized. Simulation indicates that the process control model can make rolling schedule of LP rolling adapted for different kinds of dimension of billet and product with pretty good effect, and so that it can be applied to the practical production.
