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).

If you search the Internet for what a coldrolling mill is, one might be hardpressed to find a description to relate to and understand. It is important to preface that what is involved in the process of rerolling aluminum coil or strip is quite capital intensive, which explains why there are limited mills in the United States that will flat roll aluminum coil.
· During foil or ultrathin strip rolling, elastic deflection variation of the work rolls at the contact surface with the strip causes nonuniform thickness distribution of the product in the width direction, which possibly causes a central wrinkling or an edge fracture on the product. This study developed a fourhigh prototype rolling mill, comprising two work rolls fabried from .

During rolling the working roll ends would deflect towards backup roll, thus creating a camber on working roll surface which is in contact with the sheet. The method is highly useful in automatic control of camber. This type of control is easily adaptable in computer control of cold rolling mills. Rolling Practice V/S Anisotropy in Sheet Metal:
· 1. Cold rolling of (a) thick strip and (b) thin foil. New theory of cold rolling thin foil 509 between work rolls and strip. At entry the strip moves slower than the rolls, while at exit the strip moves faster than the rolls. Noslip between the rolls and strip occurs only at a single section between entry and exit, known as the neutral section.
