Online ServicePOWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls. The ratio λ = [ a/Lp] = [a/√R.∆t] is used to
Online Service· Frequency response characteristics of the rolling mill at change of the speed setting for the first stand (1,2- for rolling speed m/s, 3,4- for rolling speed m/s; 1,3- for the first inter-stand gap, 2,4- for the second inter-stand gap). The analyses of characteristics show that dynamic properties of the strip have the main influence on the frequency bandwidth in the case under
