  • Roll Pass Design – IspatGuru

    Roll pass design is a set of methods for determining the ons, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes. Several passes are made for each section; a square or round billet or bloom acquires a specified form on each successive pass. The roll passes are designed ...
