Sendzimir mills are generally used for rolling of stainless steel and non-ferrous grades worldwide. these mills operate at speeds ranging from 500 MPM to 1000MPM. At such high speeds, it is very necessary that the material of rolls is very clean and free from inclusions and defects and should be of very good quality. DeeTee can make all sizes ...

A Sendzimir rolling mill (ZRM), one of the rolling mill systems, is a machine used to obtain a steel strip with a desired shape in cold rolling. Model based controllers are mainly used for the shape control, but it is difficult to obtain the mathematical model of the ZRM, so model identification should be used.

Sendzimir Mill (Z Mill) In a Sendzimir mill (also called a Z mill), steel is rolled in a 20-high roller configuration, which applies higher roll pressure and allows very hard and elastic materials to be rolled. Temperature monitoring ensures the steel is cooled sufficiently that it will not stick to and burn the separating paper when coiling.

Twenty-high Sendzimir rolling mills (ZRMs) typically use small diameter work rolls to provide massive pass reduction. Because of the small diameter of the work rolls, a rolled steel strip has a complex shape mixed with quarter, edge, and center waves. When the strip shape is controlled automatically, actuator saturation occurs in the shape …
