The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2high or 4high (even 6high in some cases). The mill stand can be work roll driven or back up roll driven.

60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B. Cauffiel
cast slabs into plate, the plate into hot rolled coils and the hot rolled coil into cold rolled coil. Many of these old mills are still running today as a result of upgraded electrical and hydraulic systems, including hydraulic screwdowns, hydraulic roll bend, and tension control.
Following recrystallization annealing the steel becomes nonrigid, the consequences of cold forming disappear, mechanical properties reach the values before cold forming. The next operation is skinpass rolling. The aim of the 1700 mm wide fourhigh skinpass rolling mill is to form cold rolled, annealed wide strips by 0.52.0%.
Practically the all defects in cold rolling inspected before dispatching the material to the customer at skin pass mill. R&C Inspection wings generally focused over four "S" i.e. Shape, Size, Surface and Safety during their inspection. Cold rolling improves the surface finish and holds tighter tolerances. This will certainly affect the quality
