The films were extruded through a set of nip rolls comprising a matte finish silicone rubber roll (55 Shore A) and a polished chrome chill roll. The surface of the film composite intended to be heat sealed to form the inner surface of the bag was placed against the silicone roll of the 3-roll stack and consequently had a matte finish which was ...
the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.

Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel
You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
After quenching, some specimens were cold rolled, within half an hour of quenching, to minimise any natural aging effects. The average deformation ratio during rolling was 1%, 1.5% and 3%, using a 2 hi rolling mill with two rolls of diameter 140 mm and an angular velocity of 1 rad/s. The grease-based graphite lubricant was used.

They looked for defects in the work roll bearings inner races that were likely to create similar markings to the ones experienced in the cold rolling mill, as shown in figure 3. These defects were present in all the mill work rolls and were likely created during the chocking and de-chocking operations.
