Temper Rolling Of Sheet Steel

Temper passing is performed to improve flatness minimize the tendency to stretch strain and flute.

Temper rolling of sheet steel.

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. Temper rolling with relatively small deformation usually around 1 forms the final mechanical properties planarity and surface microrelief of sheet steel. Temper rolling increases the yield point to 30 50 meganewtons per sq m 3 5 kilograms force per sq mm reducing the possibility of formation of flow lines which mar the surface of products on the metal during cold stamping. 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.

Temper rolling is the process of lightly cold rolling sheet steel. The primary purpose of a temper mill is to improve the surface finish on steel products. 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. It is typically done after the annealing process or hot roll after pickling to improve flatness minimize any tendency to stretch strain and flute and create a specific surface texture.
