THE MECHANICS OF TENSION CONTROL, core diameter and 35 inch outside roll diameter, if taper tension was set to 50%, the tension will be linearly decreased from 35 inch core to 35 inch roll diameter so the tension will be half at the outside of the roll compared to the core How do tension controls work? A word about the term driveCalculating Mill Drive RPMs: Is Your Mill Up to Speed?, The bottom throat diameter of each bottom driven roll, in each section, breakdown, fin and sizing, is the not only the drive point for these sections, but they also give reference to the "bottom" or "metal" line of the entire millROLLING, rolled to a thickness of 20 mm in one pass The roll radius is 300 mm, and the rolls rotate at 100 rpm Calculate the roll force and the power required For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and at a true strain of 0223, true stress is 280 MpaRolling (metalworking), Nov 27, 2015· When the roll diameter reduces to less than the minimum diameter required by the mill stand after turning down, then the roll is to be discarded Stand and roll guide set-up The goal of mill and the roll guide setup is to get the first bar rolled when changing product, on the cooling bed within the tolerance so that it is a saleable product1 Hot rolling and rolling defects: 11 Front and back ,, normally camber of 05 mm on roll diameter is provided Also during hot rolling, rolls get heated up and bulge out at the center, causing camber of the rolls This is due to temperature , 17 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling.
