A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal rolling conditions” - a stable, theoretical assumption - mills experience many different changes in rolling conditions. After a roll ...

The basics of roll form tooling design

Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight lengths. On a typical C channel, the return leg (bend No. 2) is the first forming to be done (see Figure 2).
