A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration 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.

In statistics, a moving average (rolling average or running average) is a calculation to analyze data points by creating a series of averages of different subsets of the full data set.

Sendzimir rolling mill is basically a single stand reversible arrangement, with great flexibility and a wide range of products. However, there are very few Sendzimir mills with a continuous arrangement.

Cluster mills are also less expensive than 18-high and 14-high mills. See illustration below showing typical cluster mills. In all cases, one of the main advantages of a cluster mill is the large back up rolls. The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll.
