Calculator for Rolled Length of Roll of Material

Calculatestherolledlength of arollof material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given. Variations due to stretching or softness of the material are to be ignored. An example ofrolled materialwould be arolledcarpet or arolledsheet of paper from the papermill.

Thecalculationofrollingforce - Innoval Technology

Thecalculationofrollingforce. When manufacturing sheet products it’s important to understand therollingforce. This is because you need it to set the appropriate roll gap on themill, accounting for the stretch of the stand. The prediction ofrollingforce can be challenging due to the large number of inter-connected process variables ...

This paper presents a completely new approach to the mechanics of the Sendzimir hot planetaryrolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, therollingload, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.
