Mill loadMILL LOAD Roll Force, Torque, Power The Mill Load appliion is specifically developed for mill design/operation engineers to calculate roll separating force, rolling torque and power, etc. Typically, load calculation is needed for an existing mill when a new rolling process is applied either with higher reduction or in lower temperature or higher speed, or for a stronger material.
Calculation of Rolling Load and Torque in the Hot ...This paper presents a completely new approach to the mechanics of the Sendzimir hot planetary rolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rolling load, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.

Calculation Of Power For A Hammer Mill PdfPower is applied to the rolling mill by applying Torque to the rolls and by using roll strip total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls. The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment
Basics of Rolling and Rolling Mills – IspatGuru · Power which is applied to the rolling mill by applying a torque to the rolls and by means of work piece tension. The power is spent principally in four ways namely (i) energy needed to deform the metal, (ii) energy needed to overcome the frictional force, (iii) power lost in the pinions and power transmission system, and (iv) electrical losses in the various motors and generators. Major ...
