The estimation of roll separation force is required for pilger mill design andto determine limits for tube dimensions or process parameters. To calculate this force accurately a reliable flow stress model is required. Since the 1950s, several models have been published to investigate the roll separation force.

PROFIL is the roll form design software for every manufacturer of cold roll-formed profiles or seamed tubes from sheet metal and for designers of roll formers and tube mills. PROFIL enables quicker working and cost reductions in planning, design, calculation and drawing of the profile, the flower pattern (bending steps) and the roll tooling.
Feb 21, 2005· The additional force from the product is a simple equation based on the material in contact with the rollers. The formulae is simply F=uW where u is the rolling friction and W is the weight of the product in pounds. For u us the following for steel conveyor rollers. Metal u = 0.01 to 0.02 Plastic u = 0.02 to 0.04 Wood u = 0.02 to 0.05
Calculator for Outside Diameter of Roll of Material Calculates the outside diameter of a roll of material when the rolled length of the material, thickness of the material, and diameter of the hole in the center or the tube on which the material is wound are given.
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
