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.
The evolution to the current 20-High Cluster Sendzimir Mill from the early 12-High configuration was pioneered by Tadeusz Sendzimir in the early 1930s. Many design improvements were made by his company, T. Sendzimir, Inc., including the flexible shaft backing assemblies, segmented idler rolls, along with tapered edge intermediate rolls with ...

Abstract: The deflection of rolls of Sendzimir mill with double AS-U-Roll was simulated by finite element method(FEM). The influences of rolling pressure, strip width and rolls-assignment on rolls deflection were analyzed. The results show that the work roll deflection increases with the increase of rolling pressure and the reduction of work roll radius, but the …

"Sendzimir was a genius, a real character. The only problem was he had so many ideas. Ninetyfive percent of them weren't any good. But the remaining five percent were so good that you forgot all the rest." That's how Tad Sendzimir is remembered by one steel-plant chief—and perhaps all of them, around the world, who own Sendzimir rolling mills.
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.
