摘　　要：针对铝板轧制过程中,轧机的锥形辊道与板材两边部接触部分速差过大会带来辊道粘铝、板材边部粘铝、划伤等问题,本课题根据轧机的速度、板材道次轧制时的前滑及后滑系数、锥形辊道的设备参数等因素,计算出能够很好地匹配轧机速度的锥形辊道线速度设定值,使板材与辊道接触位置的速度差无限接近于零,既提高辊道的使用寿命,又能使其不易粘上金属碎屑和粉末,以此来改善铝板材表面质量,同时减少人工清理辊道的工作量。In view of the problems of roll sticking,plate edge sticking and scratch caused by the excessive speed difference between the conical roller table and the contact part of the two sides of the plate in the rolling process,this paper calculates well according to the speed of the rolling mill,the forward and backward slip coefficients of the plate pass rolling,and the equipment parameters of the conical roller table.The set value of linear speed of conical roller table matching the speed of rolling mill makes the speed difference between plate and roller table infinitely close to zero,which not only improves the service life of roller table,but also makes it not easy to be stained with metal debris and powder,so as to improve the surface quality of aluminum plate and reduce the workload of manual cleaning roller table.
