Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
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.

A flywheel can be used to smooth energy fluctuations and make the energy flow intermittent operating machine more uniform. Flywheels are used in most combustion piston engines. Energy is stored mechanically in a flywheel as kinetic energy. Kinetic Energy. Kinetic energy in a flywheel can be expressed as. E f = 1/2 I ω 2 (1) where
In order to improve the calculation accuracy of tension distribution, a new method to calculate tension distribution for strip cold rolling is carried out. First, exit unit tension calculation model is developed by using variational calculus method. Then combined with divided element method, tension distribution and rolls deformation model are established, and the corresponding procedure is ...
