Sep 01, 1962· 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.

Rolling of Metals

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.
