【摘要】 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。更多还原

【Abstract】 A dynamic control arithmetic and mathematic model of secondary cooling system for ROKOP billet concasting has been developed in view of the changes of casting speed during concasting process and the high fluctuation of surface temperature due to the use of static control method. By means of computer simulation and by comparison between static and dynamic control method, it proves that the latter one is more adaptive to the changes of casting speed, which leads to lower fluctuation of surface temperature.更多还原
