Rolling mills consisting of two rolls or known as a 2 High rolling mill is used for anything from temper pass to breakdown of material. The 2 High rolling mill typically have larger diameter work rolls that are positioned with actuators that either have:
The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4high) both roll force and roll torque were available so the friction coefficient could be evaluated in addition to the flow stress for each pass. The values were close to so it was decided to use this for ...
The two roll rubber mill is used in almost every rubber production facility today. Many other inventors created rubber mills with varying degrees of similarity to Chaffee''s initial designs. [3] George Watkinson patented a three roll design in 1894 while Harold Denmire patented a four roll design in 1932.
A fourhigh mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced:
