Abstract (en)
[origin: EP0960662A2] In determining the rolling force (Fw) depending on a friction coefficient ((x)) , where x = 0 - ld, variable over the roll gap length (ld) between the roll (2) and rolled stock (1), a function of the friction coefficient (f(x) over the roll gap length (ld) depending on a vertical voltage (y = f1(x), an average flow voltage kf = kfm, a rolling angle ( = f2(x), and a correction factor, the influence of lubricants and geometric roll gap ratios is determined.
