  • (PDF) A New Method for Roll Pass Design Optimisation

    Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage, there is the continuing component of roll wear that is critical to the economics of fabrication, and the geometrical tolerances of the products.

    Roll Pass design for steelThe 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.
