ROLLING-(A Brief Guide To Rolling And Rolling Mills)

Cold rolling: Cold rolling occurs with the metal below its recrystallization temperature. It requires more pressure than a hot rolling mill.

Increase mechanical ...

Chapter 4 Surface finish and friction in cold metal rolling

2004-3-16 · 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).
