Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
cold rolling mill. 2-stand reversing cold mills combine the flexibility of single-stand reversing mills with the capacities of conventional coil-to-coil tandem mills at substantially reduced investment costs. 2-stand reversing cold mills engineered by Primetals Technologies are suitable for highest quality applications and capacities from 400,000

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.

Mill chatter in tandem cold rolling mill is a major rejection to the quality and production of the strips. In most mill vibration models, either the roll mass is usually limited to vibrate in vertical direction and vertical-horizontal directions, or the multiple rolls system is simplified to a single mass system. However, the torsional chatter is also a typical type of mill chatter, and the ...
