### POWER IN ROLLING - idc-online

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.

Horsepower (hp) is a unit of measurement of power, or the rate at which work is done. There are many different standards and types of horsepower. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
