摘　　要：详细分析了板坯温度、轧机上下工作辊直径差及转速差、单道次压下率等因素对中厚板轧件头部弯曲的影响。同时综合考虑现场实际生产时的各种影响头部弯曲的因素,从优化单道次压下率、优化咬入长度及其咬入速度等方面提出了轧件头部弯曲控制方法,实际生产中有效地控制了中厚板头部弯曲现象,效果明显。The influence factors on the head warping of plate during rolling process were analyzed including the slab temperature, difference of diameters and speed between top and bottom work rolls, reduction ratio etc. According to production practices, and taking various factors into account comprehensively, a method for head warping controlling was proposed which was to optimize reduction ratio, optimize thread in length and in speed.
