  • 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 isRoll forming basics The Fabricator,Tube and pipe mills use idlers between almost every pass to assist in forming the round. These idlers help form the strip, feed the steel into the next pass, and stabilize the section as it goes through the mill. Most roll forming does not require idlers but typically uses many more passes to make a tube.
