摘　　要：针对大规格棒材头部弯曲产生的原因,提出改善控制方法。采用特定的干槽轧制方式,防止翘头的产生。通过优化加热工艺,减轻钢坯在长度方向上的温差,减轻头部弯曲程度。采用相应的压力轧制技术抑制侧向弯曲,同时,采用尺寸相匹配的出口导卫,有效控制了棒材的头部弯曲。This paper studies the causes of head bending of large size bar and its improvement control methods.Specific dry groove rolling mode is used to prevent the occurrence of warping head.By optimizing the heating process,the temperature difference in the length direction of the billet was reduced to reduce the bending degree of the head.The corresponding pressure rolling technology is used to restrain the lateral bending.At the same time,the size of the outlet guide is matched.And the head bending of bar is effectively controlled.
