POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arcrolling mill speed calculation formula GM stone crusher machine is designed to achieve maximum productivity and high reduction ratio. From large primary jaw crusher and impact crusher to cone crusher and VSI series for secondary or tertiary stone crushing, GM can supply the right crusher as well as complete crushing plant to meet your material reduction requirements. · 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 and applied for Hot Strip Mill at Pohang Steel.
