Hot strip finishing mill is initially set up with rolling conditions such as roll speed, roll gap, and cooling pattern obtained by a set-up model. To improve the accuracy of initial roll speed setting for a 7–stand finishing mill, an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed ...
