This study proposes a method identifying static model of the Sendzimir rolling mill, a machine used to obtain a steel strip with a desired shape in cold rolling, and a data processing method using multiple valid sets of operation data to estimate it. A Sendzimir rolling mill (ZRM), one of the rolling mill systems, is a machine used to obtain a steel …

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 …

We are proud to be known as innovators in the rolling mill industry, and we are always looking ahead for challenging new technical developments. Our precise plate thickness …

Twenty-high Sendzimir rolling mills (ZRMs) typically use small diameter work rolls to provide massive rolling force. 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 …

It is difficult to obtain the desired strip shape using Sendzimir rolling mills because small diameter work rolls can be easily deformed by the rolling force. To control the strip shape effectively, it is important to understand the relationship between the behavior of the shape actuator and the variation of the strip shape. A numerical model ...

Twenty-high Sendzimir rolling mills (ZRMs) typically use small diameter work rolls to provide massive rolling force. Because of the small diameter of the work rolls, a rolled steel strip has a ...

The Work Roll in our Sendzimir Cluster mill is non-chock-supported, and it can easily be pulled out by hand or by a roll change cart for larger mills. This feature allows for a quick change of the Work Rolls, ensuring the surface quality of the strip reflects the refined polish of a new set of Work Rolls. As a result, most of the world's 400 ...

Our unique 20-High Mills feature a small, chockless work roll and cluster roll configuration supported by backing assemblies, along with complementary products. ... In Sendzimir mills, this instrument provides real-time feedback on the profile of the material, a vital function since tension in the strip makes visual inspection impossible. ...

With regard to the suffix in the Sendzimir 20-high cluster mill terminology — the number representing maxi-mum strip width — it should be noted that the mill can easily roll strip widths smaller than the maximum. Materials Rolled and Thicknesses Obtained Sendzimir's 20-high cluster mills can roll any metal, especially very hard metals.

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 shape control, but it is difficult to obtain the mathematical model of the ZRM, so model identification should be used. This study proposes a …

"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.

As one of the most popular tandem cold rolling mills, the Sendzimir rolling mill (ZRM) aims to obtain a flat steel strip shape by properly allocating the rolling pressure. To improve the performance of the ZRM, it is meaningful to adopt recently emerging deep reinforcement learning (DRL) that is powerful for difficult-to-solve and challenging …

In the 1930s and 1940s, the rolling mills, that he developed and continued to improve, started operating on large scale in the USA and Europe. By the time of his death, over 400 of the rolling mills were in operation in 35 countries around the world. Tadeusz Sendzimir obtained a total of about 120 patents in various fields (73 of them in the USA).
