Rolling Of Metals

Flat rolling •roll force: f= lwy avg •roll-strip contact length l •average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •average true stress of the strip in the roll gap y avg •assumes no friction and thus predicts lower roll .

For sheet cold rolling roll body is ground to have a little convex chamber. during rolling process roll center part bends greatly in comparison with roll edges, roll generating line gets cylindrical. rolling material gets correct dimensions along the width. grooved rolls of section rolling mills are for rolling of workpieces and section material.
