Calculation of Rolling Load and Torque in the Hot
Sep 01, 1962· This paper presents a completely new approach to the mechanics of the Sendzimir hot planetary rollingmill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rollingload, thetorqueand the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.

Plant Engineering Relationship of torque and shaftsize
Apr 13, 2015· Torque (lb-ft) = hp x 5,252/rpm Accordingly, an increase in horsepower would require more torque, as would a decrease in rpm. For example, a 100 hp motor designed for 900 rpm would require twice as much torque as a 100 hp motor designed for 1,800 rpm. Each shaft must be sized for the torsional load it is expected to carry.
