In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.

Roll pass design for slitting billet into two, three and five separate rebars. Figure 3. Roll pass design with slitting grooves for rolling of: a) angles, b) flats. The second shaping pass– so-called "slit pass" – is the final one dividing the bar into two strands. In the axis of the pass very high and narrow "knives" are
Jul 09, 2020· Roll pass design, tailored the way the mill rolls, ensures the production of the desired final product, a defect-free surface, within tolerance at the lowest possible operating cost. Identifying how a mill intends to produce is critical to creating a pass design that is conducive to the current operating style of the mill.
