(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 wear has driven engineers to minutely examine the design

Roll Pass Design – IspatGuru

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

Design the Layout and Roll Tooling. After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill. During the design phase, you'll need to consider increasing the pitch diameters of the rolls from pass to pass (also called step-up). In many situations, overfeeding or buckling between passes, particularly in the early stages,

The roll body is engraved with flat rolling holes and vertical rolling holes, and the side edges are rolled by vertical rolling holes when rolling the slab. Due to the vertical rolling pass, the upper roller has a large lifting amount, which is also called a large opening degree rolling mill. After that, it is often followed by a 1-2 batch alternately arranged billet continuous rolling mill.
