The Work Roll in a Sendzimir Cluster mill is non-chock supported, and thus, can easily be pulled out of the mill by hand. The larger mills will require a roll change cart due to the mass of the roll. In any event, the Work Rolls can be changed in 1 to 3 minutes depending on mill size. Most Sendzimir mills roll a multiple pass schedule (5-7 passes).

Here are a few of the main types of rolling mills: Continuous rolling mill. Sheet metal passes through several rolling stands, each pressing the metal thinner. Cluster rolling mill. A cluster of metal rolls are lined up to be thinned out. An example of a cluster rolling mill would be a 20-High Cluster Rolling Mill.

The FSBA (Flexible Shaft Backing Assemblies) has been developed for a 20-high Sendzimir mill. This new shape control actuator was supported by a shape analysis model based on the distribution of geometrical moment of inertia in the roll axial direction. The shape control range was doubly extended by the introduction of FSBA.

This paper established a model for calculating the contact pressure between the rolls of the Sendzimir 20-high mill based on the influence function method with considering the dispersion distribution characteristics of backup rolls. Stone's and Hirschcock's formula are used to calculate the rolling force between the work rolls and …

The first cluster mills with small-diameter work rolls came on the market in the early 1930s. They were initially used to roll low-carbon steel and very special materials in narrow widths. It was only in 1950 that the industry fully recognized the suitability of the Sendzimir cluster mill for rolling stainless steel.

Moreover, cold rolling is the key process for the thin strip edge-drop control, and a Sendzimir mill is one of the most popular cold rolling mills for silicon strips. Thus, the mastery of edge ...

The first Sendzimir mills were put into operation in Europe 1932. While this mill is a type of cluster mill, there are certain important differences between it and other cluster mills. The fundamental idea of the Sendzimir mill is the backing arrangement, characterized by one single compact and rigid hous­

A software of SM4SM (Setup Models for Sendzimir Mill) which adopting the CEM has been developed for analyzing the strip profile and the strip edge drop during the cold rolling employing a Sendzimir mill with double AS-U-Roll systems.
