Edgedrop control is important for silicon strip cold rolling, as the silicon strip is mainly used as a laminated core. Moreover, cold rolling is the key process for the thin strip edgedrop control, and a Sendzimir mill is one of the most popular cold rolling mills for silicon strips. Thus, the mastery of edgedrop control behavior for silicon strip cold rolling with a Sendzimir mill is ...

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 ...

Looper and tension control, shown in Fig. 2, is important in hot strip mills because they affect both the dimensional quality and the mass flow of a strip. The high strip tension between stands induces width shrinkage, thickness reduction and moreover can produce an edge wave on a strip. However, it does make the mass flow more stable and hence ...

Abstract A mathematical model of a striplooper system of a hot strip tandem rolling mill is developed using Hamilton's principle and the Galerkin weighted residual method. Several nonlinearities are considered and the effects of bending and dynamic forces on the accuracy of the model are studied. Based on the model, an estimator for the strip tension is proposed.
