Conclusion: From above calculations we can say that the torque obtain for rotating the transmission gearbox of rolling machine and the torque required for the rolling of metal are approximately same. The calculation obtain for the power required to operate the transmission gear box and the power required for the rolling of metal is found out to be approximately same.
Due to the growing importance of width control in strip and plate mills, edge rolling is currently an important process in hot rolling mills. Research in edge rolling has been carried out, and in the present article, models for roll force, torque, and lever arm coefficient are .
The χ is about for hot rolling and for cold rolling. 3. Experimental work. Deformation is implemented by using a rolling mill which was built in a domestic factory. The work roll of the mill has a diameter of 1070 mm. The thickness of 320×1800×3650 (mm 3) cast slab is reduced to 303 mm in initialsizing rolling (the No. 1 pass). Then the slab is rolled subsequently until all rough rolling .
The limit of transmissible torque for a rolling mill driven by backup roll is expressed approximately by D W. > P G .....(2) RPR where, G : rolling torque (total for both rolls) PR : coefficient of friction between rolls PR : rolling force.

ACCELERATION TORQUE CALCULATION: When a machine must be accelerated to a given speed in a certain amount of time, the drive system HP may have to supply additional torque during acceleration to compensate for the load inertia. The acceleration torque must be added to the normal torque requirements of the machine.

Tangential Velocity Formula. The tangential velocity is the velocity measured at any point tangent to a turning wheel. Thus tangential velocity, vt is related to the angular velocity of the wheel, ω, and the radius of the wheel, r. Vt = ω r. Vt = tangential velocity. ω = angular velocity. r = radius of wheel. Tangential Velocity Formula Questions.
torque detector in the AC/DC drive unit. It is mainly used in roughing mill and intermediate mill area. It is generated when the rolling torque exceeds the nominal torque by 25%. − Cutting signal, which is generated instantly when the blades of the flying shear is closed. These material detection signals can only be used for the
