In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section.One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects.

Live ChatEven if the design speed of the mills may be higher, these mills run at rolling speeds ranging in most cases 12 to 18 meters per second.The reason for such low speeds is the fact that operation is sensitive at small sizes and mill setting requires fine accuracy.The design of the guiding equipment inside the mill even for lopper arrangement.

Live ChatThree-roll rolling mills of the latest design.The bar mill produces straight bars of 18120 mm in diameter and bars in coil of 1852 mm in diameter.After shipment from the mill, these straight bars andor bars in coil are processed to end products fasteners, shafts, hubs, cranks, and.
Live ChatRoll and pass design is critical for this rolling technology.There are usually three to five stands arranged in various ways, each taking one to five passes.Only one pass is made through the finishing stand, which controls the final dimension and surface.Sometimes two-high reversing mills are used at the beginning in a fashion similar to.

Live ChatA good rule of thumb is to try to design all roll passes to self-feed even when running coil stock.The mill operator should not have to feed a new coil and pry the section into the next pass.Note if end-flare is a concern and a finish pass is desired, consider adding two more passes to this ten pass.
