摘要： 结合国内某厂6机架热连轧精轧机组实际条件,选取典型产品制定了带钢轧制过程中板形急停后的测量实验方案.根据此方案进行了测量实验,得到带钢机架间板凸度实测值.结合轧制过程中各道次轧制力、弯辊力及辊形曲线等实际数据,采用基于影响函数法的四辊轧机辊系弹性变形软件针对该典型产品的板形控制过程进行计算,分析了轧辊平均凸度计算值与设定值之间存在偏差的原因.将带钢机架间横向厚度分布的计算值与实测值进行比较,二者吻合较好.

Abstract: A jerky measurement of the shape of hot rolled strip was done on the 6-stand 4-high hot strip mill in a certain domestic steel plant, based on an experimental scheme. Then, the values of interstand workpiece crown, rolling force, roll bending force and actual curved surface of roll profile were measured at each and all pass, in the hot strip rolling process. Introducing the simulation software based on influence function method for the elastic deformation of a 4-high mill system into computation of workpiece shape control process, the reason why the calculated average crown values of rolls are different from the relevant setup parameters are discussed and compared. It was found that the calculated and measured values of the interstand transverse thickness distribution of workpiece are in good agreement with each other.
