  • Plate Bending Rolls, Sheet Metal Slip Rolling Machines

    On double pinch machines, the top roll position is fixed and the two lower rolls move in a straight path or an arc toward the top roll. 4 roll versions can accurately roll metal to tighter diameters and can do it in one pass through because the metal is always held by the pinch roll while the 3rd and 4th rolls take turns curving the metal.

  • 3B(2) Deformation of Rolling Mill

    The mill modulus is 500-1,000 ton/mm for plate rolling mills and 400-600 ton/mm for cold rolling mills. The larger the diameter of the back-up rolls, the higher the mill modulus. A rolling force of the order of 1,000 tons is generated during rolling, so that mill deformation of more than 1mm occurs.
