Cluster mill is normally used in cold-rolling operation. The cluster mill stand can have six rolls, 12 rolls, or 20 rolls. The 20 roll configuration is also popularly known as Sendzimir mill. In the cluster mill stand, the small and of equal size work rolls are supported in both the horizontal and vertical direction by two or more backup rolls.
