Cold Rolling - an overview ScienceDirect Topics

Cold rolling experiments were conducted on a STANAT experimental rolling mill. The mill was driven by a 12 kW DC motor, through a four-speed gearbox. The top surface speed of the rolls was 1100 mm/s. The surfaces of the 150 mm diameter, 203 mm long tool steel rolls were sandblasted, creating random roughness of Ra =0.3 μm.

Chapter 4 Surface finish and friction in cold metal rolling

In most cold rolling operations, lubricant is used to reduce frictional forces, to protect the roll and strip surfaces, and to act as a coolant. The amount of oil drawn into the roll bite and the initial surface roughness are the critical factors determining friction in the contact and surface finish of the product (Schey, 1983a and 1983b). Figure 4.1(a) illustrates schematically the inlet to ...
