cold rolling mill heating:

Induction slab heating in a hot rolling process SMS

Induction heating in cold rolling mills . For cold rolling of thin strips, the strip geometries and the material properties must be kept within close tolerances. The precise control capability of induction heating makes it particularly significant for thin strips. Along with full heating with boosters, partial heating is used in cold rolling mills.

Rolling Process: Working, Application, Defects, Type of

One is Hot rolled and another is Cold Rolled. If the strip is rolled after heating the strip above the re-crystallization temperature then it is termed as Hot rolled and if that done in room temperature then it is termed as the Cold rolled. Rolling is a process that is widely used and has very high production.

Metal aluminum sheet rolling process Mingtai AL

The slab (mainly continuous casting billet) is used as the raw material, and after heating, the fine rolling mill and the finishing mill are used to make strip steel, which is hot rolling. Cold rolling is processed from hot-rolled sheets under normal temperature tempering. Although the aluminum sheet will heat up due to rolling during the processing, it is still called cold rolling. In layman's terms, after a billet of aluminum is heated, it undergoes several passes of rolling

Rolling (metalworking) Wikipedia

In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. [1] [2] Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel,into products such as structural steel ( I-beams,angle stock, channel stock), bar stock,and rails .

Plate rolling gets hot The Fabricator

For instance, a material may require heat treating before being formed cold in a plate roll, but the mill or other material supplier may have a backlog. So in some cases, a roll shop receives as-rolled plate (without heat treating) and, via hot rolling, performs the necessary heat treatment.
