Steel Rolling Process Modeling and Mill Design Training. Module 5: Mill Force, Torque and Power Calculation Fundamentals. This module explains how to calculate roll separating force, rolling torque and mill power. For force . »More detailed
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.
Roll separating force is the main goal in calculations in N/mm They are related in all mathematical models Roll pressure varies over the surface Proportional Increased with reduction Roll separating force is used in calculating other quantities Friction, entry thickness and .

Gear unit. In wind turbines, there is a "conflict of interests" between the rotor's drive speed, limited, for example, by pitch speed, and the required rotational speed of the generator.With two pole pairs, a rotational speed of 1500 rpm is required for a mains frequency of 50 Hz. [4]. The solution is to use a gear unit. Gear units convert rotational speed and torque and transmit high power.
Resultant Force Calculator. The resultant force refers to the single force acting on an object along with their directions. The resultant will be zero when an object is subjected to have several numbers of forces acting in the same directions.
