In inplantmade mills, there is a control option presented by toggle. switch. Then, rotation goes through the gear to both of shoulders. Here, each shoulder should be aligned individually. I have set of calibrated plates for this purpose, it makes selection issue not complicated. All the rest is shown on picture.

What Is a Rolling Mill? At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level ...

Abstract. The theory of rolling metals has been adequately developed since the mid 1940's. Of the popular theories, the complex formulations are accurate over a large range of rolling conditions, and the approximate formulations tend to be accurate only on a narrow range. This paper covers the development of an approximate formulation of the Orowan (1943) rolling theory that is applicable ...

The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also to generate a constant specific ...
