Indian Standard Heavy Weight Beams ISHB. The cross section of a rolled steel beam is shown in Fig. 2.1. The beam section consists of web and two flanges. The junction between the flange and the web is known as fillet. These hot rolled steel beam sections have sloping flanges.

New Rolling Method Of Reversing Cold Rolling Mill

mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll

6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.

geometries, like square, diamond, round, oval, box etc. Roll-pass design, which decides the shape, size and combination of the grooves, is a complex work. However, using an optimal roll-pass design will result in defect free products with correct dimension. In the work of improving the roll-pass design finite element simulations are a useful tool.

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. Design the Layout and Roll Tooling

May 21, 2010· A suction roll is one of the most important process rolls and also one of the most costly rolls to maintain in a paper machine. By optimizing suction roll maintenance, a paper mill can reduce total maintenance costs, enhance roll reliability, lengthen service intervals and increase the total lifetime of the suction roll.

Fundamentals of Rolling | ScienceDirect

Abstract: The rolling conditions for heavy sections are very complicated and may create different surface problems (uneven wear, fire cracks, sticking) in various areas of the passes. Additionally the roll pass design influences wear. Rolling loads – especially due to rolling accidents - may cause breakages of the barrel or of collars.
