Hot-roll

verbStandard termMetallurgy

To pass metal through rollers at a temperature high enough to prevent work hardening.

To deform metal by passing it between heavy rollers while it is heated above its recrystallization temperature. This process reduces the thickness of the metal and refines its grain structure without causing it to become brittle, allowing for massive reductions in a single pass.

Heard on the job
