Rolling (metalworking) - Wikipedia

In flat rolling the final shape of the product is either classed as sheet, also called "strip" (thickness less than 3 mm,) or plate (thickness more than 3 mm). In profile rolling, the final product is either a round rod or other cross sections shaped products such as structural sections (beam, channel, joist, rails, etc).

This paper presents a three dimensional analysis for hot rolling of channel section beams by the finite element method using ABAQUS/Explicit. A complete production line containing 13 passes for forming the section including break-down, intermediate and finishing sequences are modeled, and the exit section of each pass is imported as the entering material for the next pass.
