Structural Shapes – standard steel configurations produced by steel mills such as wide flanges, channels, angles, pipe, tubes, etc. Structural Steel – the structural elements that make up the frame that are essential to supporting the design loads, e.g. beams, columns, braces, plate, trusses, and fasteners. It does not include for example ...

Mar 27, 2003 The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain.

MILL LOAD - Roll Force, Torque, Power The Mill Load application is specifically developed for mill design/operation engineers to calculate roll separating force, rolling torque and power, etc. Typically, load calculation is needed for an existing mill when a new rolling process is applied either with higher reduction or in lower temperature or higher speed, or for a stronger material.

In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section. One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects.
