Hot Rolling Process

Unlike cold rolling, the hot rolling process is carried out above recrystallization temperature. The component produced by this method does not get work hardened. Large cross sectional change is possible by this method. For producing the hollow cross sectional components, additional mandrill is used along with the rollers.

Level of surface finish achieved: 50-6.3 micro meters

Advantages:

–      Drastic shape change is possible

–      Good microstructure and good strength

Disadvantages:

–      Less dimensional tolerance compared to cold rolling.

–      Poor surface finish.

Ideal applications: Ideal for making long structural members like I-beam, C-channel, tubular sections etc. normally made up of structural steel.
