The sheet metal rolling. is the way to obtain the hot or cold plastic deformation of a metal, progressively reducing its thickness. The main types of rolling mills are named according to the number of cylinders which make up each rolling stand. This is the fundamental part of the mill, and consists mainly of working cylinders

*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configuration is often used for heightstrength and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the
This paper deals with the shape control methodology for Sendzimir coldrolling steel mills. Due to the several problems which come from the Sendzimir mills' complicate structure, designing automatic shape control system for these mills was one of the main control issues in cold rolling industries. The multivariable problem and model ...

SMS group ranks among the leading suppliers of plant technology and equipment for the production of highquality stainless steel strip. Our portfolio of cold rolling mills for stainless steel comprises standalone 20high mills in MonoBlock and SplitBlockdesign as well as our 18HS stands which are also suited for integration and use in continuous mills.
In order to solve strip edge drop and crown problem for accurate "dead flat" transverse thickness profile of electrical steel sheet in 4high tandem cold rolling mills,the 3D finite element model of roll stacks and strip deformation was built in cold rolling process. Through a comparative analysis, the uneven deformation of rolls flattening and the deflection of work rolls caused by the ...

Abstract and Figures. Deals with the problem of shape (or flatness) control for Sendzimir 20roll coldrolling steel mills. Such mills, with a variety of shape actuators, offer the control ...
Sendzimir process (named after Tadeusz Sendzimir) is used to galvanize a steel strip by using a small amount of aluminum in the zinc bath and producing a coating with essentially no iron zinc alloy. The process guarantees high resistance and durability characteristics.
The ZMill or Sendzimir Mill is a machine for rolling steels. [1] [2] Unlike a traditional rolling mill this 20high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center.
Sendzimir cold rolling mill . The Sendzimir cold rolling mills are located in cold rolling mill plant 1. At the Sendzimir cold rolling mill, the steel strip is fed from the feed coiler through the rolling mill to coiler 2 and from there back to coiler 1. Between the coilers is the rolling mill section that rolls the strip thinner and thinner

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 difficulttosolve and challenging problems. However, the direct application of DRL ...
FIG. 5 shows an application of the strip wiper assembly A of the present invention for use with a Sendzimir coldrolling mill 100 wherein the strip travel direction is indicated by the arrow 102. As is known, Sendzimir coldrolling mills feature several roll arrangements, a typical one of which is the 1234 arrangement illustrated in FIG. 5.
A software of SM4SM (Setup Models for Sendzimir Mill) which adopting the CEM has been developed for analyzing the strip profile and the strip edge drop during the cold rolling employing a Sendzimir mill with double ASURoll systems. Moreover, the influences of the 1st intermediate roll (IMR) taper slope, taper length and shifting, the 2nd IMR ...
