摘　　要：基于中厚板轧制中轧件头尾翘曲产生机理,分析轧件上下表面的温度差、轧制压下率、轧制导入角、异径异速轧制和变形区几何形状等对板材翘曲的影响,并总结了中厚板轧制翘曲的控制方法。Based on the formation mechanism of head and tail ski - up on rolling piece during medium and heavy steel plate rolling, the article analyzes the effects of upper/lower surface temperature difference, rolling reduction , rolling piece biting - in angle, different roll diameter and different roll speed rolling and geometrical shape of deforming area on steel plate warping, summaries the warping control solution of medium and heavy plate rolling.
