Sendzimir Mill (Z Mill) In a Sendzimir mill (also called a Z mill), steel is rolled in a 20high 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.

Twentyhigh 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 actuator such as ASU rack. These problems affect ...
