Rolling mill power calculation

Rolling mill power calculation

The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm ‘a’ λ =0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure
