The paper compares and contrasts various controller possibilities and is intended to provide a "cookbook" of shape control tools and strategies for Sendzimir mills. Deals with the problem of shape (or flatness) control for Sendzimir 20-roll cold-rolling steel mills. Such mills, with a variety of shape actuators, offer the control engineer considerable choice in the configuration and …

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.

Robust Shape Control in a Sendzimir Cold-Rolling Steel Mill 1651 Note that, by virtue of the parameterisation in eq. (9), no attempt is made to control the high-order profiles, which accords with normal rolling practice. Parametric shape variations (with desired values of zero), which are shown as the output in Fig. 5, are given in Fig. 9.

Vibration analysis of a Sendzimir cold rolling mill and bearing fault detection E Brusa, L Lemma, and D Benasciutti Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science 2009 224 : 8, 1645-1654
Vibration analysis of a Sendzimir cold rolling mill and bearing fault detection. Abstract The presence of several rolls in cluster cold rolling mills makes on-line vibration monitoring and failure analysis difficult. The dynamic behaviour of rolls strongly depends on the rolling pressure in the roll bite.
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 ...

The essential difference between Sendzimir mill (Sendzimir cold rolling mill) and other types of the mill is the direction of rolling force transmission. The rolling force of Sendzimir mill is transferred from the working roll through the intermediate roll to the supporting roll device and eventually to the solid overall stand.

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 …
Abstract. The shape control problem for a Sendzimir 20-roll cold rolling steel mill is characterised by operation over a wide range of conditions arising from roll changes, changes in rolling schedules and changes in material gauge, width and hardness. Previous approaches to the problem suggest storing a large number of precompensator matrices ...
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.

Product quality and low scrap rates are supported during this high-pressure rolling process by accurate non-contact temperature measurements. We provide the infrared SPOT M210 thermometer, suitable for a wide temperature range, for this application.
Sendzimir had little more to do with galvanizing; he wanted to concentrate on his cold mill instead. In the 1990s a modern galvanizing line bears as much resemblance to the simple steel furnace box Sendzimir built in Poland as a Harley-Davidson does to a bicycle, but at its core you will find the same physical and chemical process.

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.
A cluster type rolling mill intended to provide work roll sizes in the range between the small sizes available with current cluster mill designs and the large sizes available with current four-high mill designs is disclosed. This mill combines the advantages of existing cluster mills (heavier reductions per pass and between anneals) with the advantages of four-high mills …
