What is Temper Rolling? Steel Foundations

The primary purpose of temper rolling is to improve the surface appearance and mechanical properties of a metal coil through a process called cold rolling.

The cold rolling process unrolls a metal coil and passes it between a set of work rolls at room temperature, where the compressive force of the rolls causes a reduction in the thickness of the metal. Typically, the amount of metal thickness reduction performed at temper rolling is minimal (0.5% to 2.0%).

Temper rolling is done on a temper mill, which is composed of an entry end uncoiler, a cold rolling mill stand, advanced metal thickness control equipment, oiling equipment, and an exit end recoiler.

The physical properties that are enhanced by the cold rolling done at the temper mill include:

  • Improved thickness accuracy and repeatability
  • Improved product surface finish
  • Improved product shape and flatness
  • Decreased coil memory
  • Increased material strength to the desired hardness or temper
