摘　　要：采用刚塑性有限元法建立立辊调宽和随后平轧宽展过程的三维热应力耦合模型 ,对宝钢 2 0 5 0热粗轧机组带钢的头尾形状短行程控制 (SSC)进行了研究。通过分析各种压下制度下的头尾部失宽规律 ,建立了立轧带钢头尾部短行程控制模型。对比宝钢现场采用的短行程模型和研究所取得的新模型可以看出 ,新的短行程控制模型对头尾部形状有更好的改善作用。A 3D thermal-mechanical coupled FEA mod el for edging and horizontal rolling was established.It has been used to invest igate the SSC model for controlling head and tail shape on the roughing trains o f 2050 mm hot strip mill at Baosteel.The law of width reduction on head and tai l ends was analyzed, and a new SSC model was established as a function of both s trip width and draught of edging.By comparing results calculated by original mo del and new model, it can be seen that the width reduction of head and tail ends can be well decreased by the SSC with established model.
