A steel mill in Butler, Pennsylvania was established by Sendzimir in 1936. By 1938 Armco Steel became interested in his work and they formed a partnership with him, the Armzen Company, to oversee the worldwide expansion of his galvanizing and mill technology. In the spring of 1939 Sendzimir moved to Middletown, Ohio.
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.
Facing these additional critical features, the new mill design should mingle the conventional advantages with modern design concepts – a hybrid design. ... In addition, the Sendzimir mill is a ...
The 20-Hi roll cluster contains 12 rolls and eight backing bearing assemblies. A rigid, compact mill housing eliminates deflection of work rolls and produces a uniformly close gauge tolerance strip. Waterbury Farrel supplies 20-Hi Mills in either reversing or one-way operations. Waterbury Farrel developed and patented the Sendzimir (Z-mill) in ...

High rigidity twenty-high Sendzimir mills (ZRMs) are widely used for rolling stainless steels, silicon sheets, etc. A ZRM uses a small diameter work roll to produce massive rolling forces. Since a work roll with a small diameter can be bent easily, strips often have complex shapes with mixed quarter and deep edge waves in the shape of …
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 …
The calculation of force for a roll system has significant effects on cold rolled thin strip gauge adjustment of a 20-high Sendzimir mill. According to the rolling parameters and rolling plans of a ZR-22BS-42 Sendzimir mill in a silicon steel factory, the contact force and the resultant force of each roll in the roll system were calculated both …
In a Sendzimir mill (also called a Z mill), steel is rolled in a 20-high roller configuration, which applies higher roll pressure and allows very hard and elastic materials to be rolled. Temperature monitoring ensures the steel is cooled sufficiently that it will not stick to and burn the separating paper when coiling.

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
A sound model for the prediction of the deformed roll profile during flat rolling is vital for the precision control of the strip profile and strip shape. However, preliminary investigations reveal that the applicability of existing models may be limited due to their inherent predictions errors. In this paper, a new model is proposed which is capable of …
