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.
Twenty-high 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 AS-U rack.

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. For example, Japan Sendzimir Corporation designed a set of 1270 mm four-stand full-continuous 20-roll Sendzimir mill in 1969.
The cluster mill, or Sendzimir mill, uses a small work roll backed up by many other rolls. This extremely rigid setup is often used for cold rolling high strength material to a very thin width. Figure:146 : The tandem rolling mill consists of several stands, that the work material constantly passes through. At each stand the thickness of the ...

Sendzimir Mill Rolling to Final Gauge • For thin gauge, specialized rolling mills are used to achieve uniform cross-strip thickness and flawless surfaces on material down to 0.001" (0.025 mm). • Arnold does, incidentally, roll other alloys to as little as 85 millionths of an inch (0.000085") on Sendzimir mills.
Z-Mill, Cluster or Sendzimir Mill. It is common for steel rolling mills to have backing rollers in a stand, but a Sendzimir mill has nine backing rollers on each side! This allows the working rolls to exert the pressure needed to cold roll harder metals such as stainless steel without bending the rolls.

The Sendzimir process is a surface coating process where the workpiece is dipped into a bath of zinc and aluminum to form a surface. This process named after Tadeusz Sendzimir is used to galvanize a steel strip by using a small amount of aluminum in the zinc bath and producing a coating with essentially no iron-zinc alloy.

A few Sendzimir Mills were built in Europe before WW II stopped construction of experimental steel plants. While Sendzimir was working at Armco, Signode Steel in Chicago ordered on of his "Z" Mills (Sendzimir Mills are called "Z" Mills in the United States). Signode used the mill to successfully roll low carbon steel for strapping and more ...
Mark Zipf of Cold Rolling Technologies Inc. used a historical collection of mill images that have been archived since the original installation in 1965, along with recent equipment performance studies to explain the general nature of the Sendzimir mill equipment, and the specific nature of the machine installed at the NLMK Pennsylvania plant.

Cluster mill or Sendzimir mill stand – In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [0.0025 mm thick]. The work roll in these mills can be as small as 6 mm diameter – made of tungsten carbide.
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. The mechanical model of the work roll, first intermediate roll, second intermediate driven roll, and second intermediate idler roll was proposed and the contact force of each roll …
