Jun 18, 2014· Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes.
May 18, 2015· Roll pass design in continuous bar mills 1. African Foundries Ltd. Lagos, Nigeria Presented by Rahul Kishore 2. Basics of Rolling A rolling mill consist of several, at least two rolls cylindrical or nearly cylindrical bodies which are termed as "roll" and which rest in bearings at their ends. The normal and average center distance from the center of one roll to the center of o
mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...
*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configu-ration is often used for height-strength- and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the
