Cold rolling: Cold rolling occurs with the metal below its recrystallization temperature. It requires more pressure than a hot rolling mill. Cold rolling is carried out by industries to obtain sheets, strips, foils, bars, etc. Advantages of cold rolling mills are: Good surface finish. Close control to product dimensions. Increase mechanical ...
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).
