control algorithms and to help determine process improvements. 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

What is Cold Rolling? (with picture) wiseGEEK

02/02/2021 Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls. These rolls rotate in opposite directions at a consistent rate of speed, and they are set apart so their width is smaller

Numerical Simulation and Parameter Design of Strip Cold

In the cold rolling process of 20 high rolling mill, the strip and roll are deformed by rolling force. Due to the large stiffness of rolls, most of the load is dispersed on the frame, so the deformation of the roll is approxi-mately considered as elastic deformation. Also, the strip thickness direction has large deformation. In order to make the finite element model more accurate, a rolling

Best Practice Lubrication for Paper Machines

Sometimes, mill personnel choose oil rather than grease for lubricating bearings in the wet section. This may occur for one of a number of reasons. For example, in relatively high-speed forming sections, elevated operating temperatures may require excessive grease for relubrication. The right oil may be more economical and less messy.
