Universal Beams and its Rolling | ispatguru

The typical mill layout for such a rolling mill is at Fig 2. The universal roughing and edging mills are reversing multiple pass mills that run in tandem through computerized speed matching. The universal roughing mill is normally a four-roll mill with two driven horizontal rolls and two non-driven vertical rolls.

2019-4-23 · Rolling schematic view Rolling visualization. (Click on image to view animation.) In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the

New multi-pass hot channel section rolling design by

2018-2-6 · A new multi-pass hot shape rolling was designed based on a three-dimensional analysis of channel section beams in hot rolling by the finite element method. A complete production line in industry containing 13 passes in forming the section including break-down, intermediate, and finishing sequences is modeled. The output geometry and power consumption predicted by this simulation were verified
