深入研究了鞍钢1450冷连轧机板形控制系统的板形检测原理及控制方法。在进行较大压下量的轧制时,带钢的变形会导致沿带钢宽度方向上的横向温差增大,由于该板形控制系统未考虑带钢横向温差对板形测量的影响,当带钢横向温差较大时,板形控制效果不太理想。针对该板形控制系统存在的不足,增加了板形目标曲线的温度补偿环节。结果表明:增加温度补偿后减少了带钢横向温差引起的板形缺陷,提高了板形控制精度。
In-depth study of the Ansteel 1450 tandem cold mill shape control system of the plate-shaped detection principle and control methods. The deformation of the strip leads to an increase in the lateral temperature difference along the width of the strip during the rolling with a large reduction. Since this strip-shaped control system does not consider the influence of the lateral temperature difference on the strip shape measurement, Strip transverse temperature difference is larger, the shape control effect is not ideal. For the lack of shape control system, an increase of the shape of the target curve of the temperature compensation link. The results show that after the temperature compensation is added, the plate-shaped defects caused by the lateral temperature difference of the strip are reduced, and the control accuracy of the strip shape is improved.
