20-roll stands, so-called Sendzimir planetary rolling mills, have become established for cold rolling stainless steels. They can best meet the demands for high forming levels, tight tolerances and good surface Annealing. The material hardened during cold rolling must undergo recrystallising annealing to restore the forming properties for further processing. This takes place in batch

· 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
The main difference between Sendzimir 20-high mills and other 4-bar mills is the different transmission direction of rolling forces. The rolling force of Sendzimir is transmitted from working rollers to middle rollers then to supporting rollers and finally to the stubborn frame. The design assures the supporting of working rollers along the length side. This kind of rolling system is not easy
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

The overall frame structure of the sendzimir 20 high rolling mill has the advantages of great rigidity, bearing the rolling force along the entire width of the rolling mill through the backing bearing, and therefore the longitudinal and lateral dimensional accuracy of the strip is high. Therefore, it has been widely used in the cold rolling industry. The 20-roll mill is suitable for strip

· The Sendzimir mill is specifically designed for processing stainless steel and other metals which rapidly work harden during cold rolling, making gauge reduction A typical Sendzimir rolling stand is immediately recognisable by its large number of small diameter back-up rolls (typically about 20) clustered around two small-diameter work rolls.
A Sendzimir rolling mill (ZRM), one of the rolling mill systems, is a machine used to obtain a steel strip with a desired shape in cold rolling. Model based controllers are mainly used for the
Ein Sendzimir-Gerüst ist eine Vielwalzen-Gerüstkonstruktion ( mill) zum Kaltwalzen, mit dem Flachprodukte besonders toleranzarm und dünn gewalzt werden können. Es ist nach seinem Erfinder Tadeusz Sendzimir benannt, der das Grundprinzip im Juli 1935 zum Patent Funktionsweise. Basierend auf einem im Jahre 1930 von Wilhelm Rohn entwickelten Mehrrollenwalzwerk, bei dem
20-Rollen-Walzwerke der SMS Group - Technologie, die sich auszahlt. Sie profitieren von unseren 20-Rollen-Walzwerken weil sie ausgestattet sind mit hochmodernen Mechanismen, Hydrauliken, Elektronik und Automation. Und: Diese Funktionen lassen sich auch einfach in bestehende Walzwerke integrieren.
Sendzimir's rolling process departed dramatically from the multi-stand continuous process developed by John Tytus Armco (1924). Instead of using multi-stand four high rolls Sendzimir's mill used a clustered nest of rolls, like two inverted pyramids (1-2-3-4 configuration). A few Sendzimir Mills were built in Europe before WW II stopped construction of experimental steel plants. While Sendzimir
Sendzimir Company has authorized the manufacture and installation of more than 600 sets of rolling mills in more than 40 countries around the world for the production of stainless steel, electrical steel, alloy steel and other difficult-to-roll strips. American Sendzimir Company authorized metallurgical equipment manufacturers to manufacture Sendzimir rolling mills through authorization
Cluster rolling mill or sendzimir rolling mill: Each of the working rolls is supported by two backing rolls. Here rigidity is well maintained. Cluster rolling mills are used for the high draft. Typical arrangement of rollers for rolling mill: Continuous rolling mill: Uses a series of rolling mill and each set is called a strand. The strip will be moving at different velocities at each stage in
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was
Sendzimir mills are famous for their ability to realize efficient rolling result by the high rigid mill housing with small diameter work rolls. The functions of AS-U and lateral shifting of intermediate roll result in the achievement of accurate shape control. Sendzimir mills supplied by SEJAL have been in operation in a number of countries in the world. We introduce range, features and flow

Sendzimir rolling mills consist in a cluster of rolls as shown in the following picture: Basic layout Work rolls have small sizes, which allows higher reductions. Furthermore, because of its easy handling, they can be easily changed, ensuring the highest surface quality. With the aim to reduce the size of the work rolls, Sendzimir rolling mills have back-up rolls to withstand the high
By the Sendzimir rolling mill it is possible to obtain, with a single pass, very high section reductions comparable to those achievable in a duo rolling mill with 5 ÷ 6 passes. SENDZIMIR BACK-UP ROLLER. WITH TWO/THREE/FOUR ROWS OF ROLLERS. Shoulder bearings have been projected on purpose for Sendzimir cold steel mills: they can be used also in straightening or flattening machines. Shoulder
· Because of its high rolling speed and precision, the Sendzimir mill is favored by some high-end users for rolling ultra-thin strips and silicon steel, stainless steel and so on. The mills of the Sendzimir mill use tool steel, abrasive steel, and high-speed steel. Higher quenching and tempering temperatures are typically required during the manufacturing process. In order to meet the hardness
· Sendzimir Mill Features . The Sendzimir mill arch is integrally cast and pre-stressed, and a circular arc track is provided in the arch to secure the backup roll. All the intermediate rolls are fixed on the arch by the suspension hydraulic cylinders on the transmission side and the operation side, and the suspension force is set according to the weight of the roller body.
· 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.
