摘　　要：为解决PC热带钢连轧机辊间接触载荷不均易造成支撑辊辊面提前损坏的问题 ,对支撑辊肩部辊形进行了优化设计。经试验验证 ,采用幂函数的辊形优化曲线可提高支撑辊使用寿命 ,并有利于板凸度和板形控制。The earlier damage to the surface of backup rolls for 1580mm PC hot strip mill is usually caused by the uneven contact pressure between rolls. In this connection, a lot of studies and experiments have been made on the optimization of the edge curve of backup roll body.The results we obtained prove that the power function curve can not only improve the service life of the backup roll but also benefit the profile and shape control of hot rolled strip.
