Roll Pass Design – IspatGuru

Jun 18, 2014  Roll pass design is a set of methods for determining the dimensions, 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 ...

Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls. The subsequent passes in rolling section steel are called roughing passes.

Setting up the Fin Section - Roll-Kraft

Setting up the Fin Section. The primary job of the fin section on any tube or pipe mill is to prepare the edges of the strip (parallel) for welding, and set the body of the tube. The only way this will take place, is if we properly set (work) each and every driven and side pass station in the fin section as per the tooling design and set up chart.
