Mechanics of Cold Rolling of Thin Strip | IntechOpen
— The lubrication and friction of the strip is a key issue in cold rolling process. The values of the friction coefficient may change significantly in different cold rolling mills and different operating conditions. The effects of the different friction coefficients on the edge contact of the work rolls are shown in Table 5 and Fig. 14. The entry ...

and on the ends of the friction sleeve. This effect is often referred to as the unequal end-area effect (Campanella et al. 1982). Many commercial cones now have equal end-area friction sleeves that essentially remove the need for any cor-rection to f s and hence, provide more reliable sleeve friction values. However, the unequal end-area effect ...
Roll Mill
The distance between the mill rolls can be varied and this gap is known as nip. The speed difference between the rolls is called friction ratio and it allows the shearing action. The back roll moves faster than the front roll; a common friction ratio is 1:1.25. Two roll mill mixing is also known as open mill mixing.
