Rolling of Steel in a Modern Long Product Rolling Mill,
19/06/2017· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills.

The primary objective of the roll pass design is toRoll Pass design for hot flat rolling of plain carbon steel,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.Roll Pass Design – IspatGuru,18/06/2014· 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 each successive pass. The roll passes are designed to avoid excessive stresses in the steelSchweitzer Engineering and Rolling Technology,We pride ourselves for developing the highest quality roll pass design to ferrous and non-ferrous hot rolling mills for production of the most challenging sections.

More forming must then be done by the weld rolls and during this forming some edge distortion will occur. This would be more problematic on heavy wall tubes. When this happens we can alter the contour of the last fin pass to an oval shape so the strip edges more closely match the weld roll radii and,,,
