  • Effect of pass schedule and groove design on the metal

    The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually designed based on the type of grades and dimensions of the products and the mill capacity. These have been established over the years based on ana-lytical methods. With modern capability of computer based simulation of the hot deformation process, it isA BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING ,Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high
