Twenty high Sendzimir rolling mills ZRMs typically use small diameter work rolls to provide massive pass reduction 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 as AS
control performance of a 20 high Sendzimir mill the roll system and deformation of the plate rolling of 20 high Sendzimir mill at a silicon steel factory were simulated and calculated The results show that the shape control ability of dual ASU is about times as much as single ASU The smooth transition of the cone angle of the conical section

Edge drop control is important for silicon strip cold rolling as the silicon strip is mainly used as a laminated core Moreover cold rolling is the key process for the thin strip edge drop control and a Sendzimir mill is one of the most popular cold rolling mills for silicon strips Thus the mastery of edge drop control behavior for silicon strip cold rolling with a Sendzimir
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 problems However the
The universal crown mill UCM cold rolling mill four high rolling mill six high rolling mill and the Sendzimir mill are all common equipment for the production of cold rolled silicon strips The Sendzimir mill with a small working roll diameter the large overall stiffness of the rolling mill and rich edge drop control methods is the

A Sendzimir rolling mill ZRM is a reversible rolling mill that can change transfer direction and is widely used for roll ing high strength materials such as stainless steel and electrical steel A ZRM uses small diameter work rolls that can roll steel with very high deformation resistance To reduce the deforma
3 Sendzimir 20 high cluster mills commonly carry the prefix ZR which stands for Zimna the Polish word for cold and reversing and the widest strip that the mill can roll The number immediately following the ZR indicates the mill section size comprising a combination of the backing bearings the work rolls
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 the static state and in the rolling
The Z Mill or Sendzimir Mill is a machine for rolling steels [1] [2] 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

Sendzimir s Process Line Z High® Mill work roll is large enough to take a significant draft reduction H1 H2 on heavier gauges 8 10 mm without skidding while at the same time having a sufficiently small diameter work roll to get down to thinner gauges 1 mm The lightweight chockless work roll can be exchanged in under a minute
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 Expand 3 Highly Influenced PDF
Twenty high Sendzimir rolling mills ZRMs typically use small diameter work rolls to provide massive pass reduction 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 as AS U rack
Before Nisshin Steel s tandem mill was even considered only a few Sendzimir mills in the world were being used to reduce or skinpass strip on a once through basis Most Sendzimir cluster mills were being used in a series of reversing operations Sendzimir has developed several mill arrangements but the dominant layout is the 1 2 3 4
Chang et al Lu et al and Xuan et al [7][8][9] developed a model of roll stacks and strip deformation and proposed the reasons of edge drop in the silicon strips cold rolling for the four
