针对连铸过程中拉速等因素变化,铸坯二次冷却实行静态控制而引起表面温度过大波动的问题,发展了一种针对ROKOP高效方坯连铸的二冷喷水动态控制算法及其相应的二冷动态控制模型。通过在计算机上的仿真实验及对静态和动态结果的对比表明,该种算法对连铸过程中拉速的变化具有良好的适应能力,拉速引起的表面温度波动很小。
Aiming at the problem of casting speed and other factors, the secondary cooling of slab is controlled by static control, which causes the surface temperature to fluctuate excessively. A dynamic control algorithm of secondary cooling water for ROKOP efficient billet continuous casting is developed Corresponding two cold dynamic control model. The simulation experiment on the computer and comparison between the static and dynamic results show that the algorithm has good adaptability to the variation of the pulling speed in the continuous casting process, and the surface temperature caused by pulling speed has little fluctuation.
