摘　　要：针对某钢厂1450 mm冷连轧机组实际生产过程中轧制状态不稳定和板形异常的问题,研究了热轧来料对成品带钢板形的影响。首先建立了来料特性和成品带钢板形之间的关系模型,在此基础上编制了来料对成品带钢板形影响模拟软件。结合软件分析了来料凸度、来料局部高点、来料板形、变形抗力分布以及来料楔形对成品带钢碎浪的影响;并定量模拟出冷连轧机组生产过程中典型规格产品来料凸度、板形、变形抗力分布、局部高点和楔形变化时成品带钢碎浪的变化情况;通过对比现场生产参数,得出模拟结果的准确性,并据此给出了来料的工艺规范。Aimed at the problems of unstable rolling state and abnormal shape in the actual production process of 1450 mm cold continuous rolling mill in a steel plant,the influence of hot rolling incoming material on shape of finished strip steel was studied.Firstly,the relationship model between the incoming material characteristic and the shape of finished strip steel was established,and on this basis,the simulation software for the influence of incoming materials on shape of finished strip steel was compiled.The influence of crown,local high points,shape,distribution of deformation resistance and wedge of incoming material on the wave breaking of finished strip steel was analyzed with software.The variation of the wave breaking of the finished strip steel when the crown,shape,distribution of deformation resistance,local high point and wedge of the typical products changed during the production process of the cold continuous mill was simulated quantitatively.By comparing the actual production parameters,the accuracy of the simulation results was obtained,according to which the process specification of the incoming materials was given.
