Temper Rolling Of Sheet Steel

The primary purpose of a temper mill is to improve the surface finish on steel products.

Temper rolling of sheet steel.

The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper pass. Temper passing is performed to improve flatness minimize the tendency to stretch strain and flute. Temper rolling with relatively small deformation usually around 1 forms the final mechanical properties planarity and surface microrelief of sheet steel. The thickness of the steel is typically reduced by 0 5 percent to 3 percent and can be used to change the gauge and inconsistencies of the steel.

It will also ensure your steel obtains your desired surface texture and mechanical properties. Temper rolling is necessary for sheet metal that is to undergo cold forging with deep drawing such as sheet steel intended for making motor vehicle body parts so called auto steel and sheet iron. A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system. This increases the density of the steel by reducing its overall thickness between usually 1 5 to 2 without allowing the steel to spread out while under pressure.
