20 hi sendzimir rolling mills

It applies to simple mill configurations, such as the common 4-high rolling mill, in addition to complex mill types, such as the 20-high Sendzimir mill. The inherent benefits over traditional strip profile models include non-discrete elastic foundations, cubic displacement fields, rapid solution, and mixed boundary conditions.

A 20-high Sendzimir mill is widely used in cold rolling. The deformation of rolls within the roll system as a whole is analyzed without pin-pointing upon each roll and impact on the rolling process.

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.

Unlike a traditional rolling mill, a Z-High® mill is a 20-high cluster mill configuration that utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality. As a result, very hard and ...
