In 5 stands rolling mill, roll cooling selectospray of the last stand effectively eliminates the shape defects. Accurate roll cooling can release the stress within the roll, extend the life of rolls, and improve rolled strip shape quality and surface cleanliness. The application and the function of the sophisticated cooling system are synthetical-ly analyzed according to the export strip temperature high and the shape control system of the 1 420 mm rolling mill for the vibration of mill at the limit rolling.
