摘　　要：热轧产品宽度精度是影响带钢质量最重要的指标之一,其直接影响到成材率与后续用户的钢材利用率。热轧产线中的生产原料来自于连铸,由于在连铸阶段,宽度影响因素多,经常会出现楔形坯(T型坯)。为了加强对粗轧楔形坯宽度的精度控制,提出了一种楔形坯的宽度控制方法,通过在R1机架立辊轧制时采用长行程与短行程结合,保证整体带钢宽度的均匀性。Product width accuracy is one of the most important indicators affecting the quality of hot rolled strip.It directly affects the yield and the steel utilization rate of subsequent users.The raw materials in the hot rolling line come from continuous casting.Because of the many factors affecting the width during the continuous casting stage,wedge slab(T-shaped slab)often occur.In order to strengthen the control precision of the width of the rough-rolled wedge slab,this paper proposes a method for controlling the width of the wedge slab,which combines the long stroke and the short stroke to ensure the uniformity of the overall strip width.
