Metals 2018, 8, 783 2 of 12 mill for the production of coldrolled silicon strips. However, the edgedrop control for the silicon strips has always been a research hotspot of various mills [68].
This paper established a model for calculating the contact pressure between the rolls of the Sendzimir 20high mill based on the influence function method with considering the dispersion distribution characteristics of backup rolls. Stone's and Hirschcock's formula are used to calculate the rolling force between the work rolls and the rolling ...

This paper presents the implemtation of a predictive functional controller for the sendzimir 20high cold rolling mill. The complete mill model is presented and contains two parts, the static ...
Compared with hot rolling, the studies of cold rolling temperature have the following differences: (1) the friction heat accounts for quite a part of the total heat in rolling deformation zone, so ...
Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
*) 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
Unlike a traditional rolling mill, a ZHigh® mill is a 20high cluster mill configuration that 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. As a result, very hard and ...
The overall frame structure of the 20high rolling mill has the advantages of great rigidity, bearing the rolling force along the entire width of the rolling mill through the backing bearing, and therefore the longitudinal and lateral dimensional accuracy of the strip is high. Therefore, it has been widely used in the cold rolling industry.
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 ...
Modern, efficient cold rolling mills can roll pickled sheets or strips at speeds of up to 4 m/s and tandem mills that are continuously working can produce up to million tons of cold rolled steel annually. The advantages of cold rolling. Cold rolled products have the following advantages over hot rolled: greater dimensional accuracy

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 fourstand fullcontinuous 20roll Sendzimir mill in 1969.
Context 1 ... the rolling process, a roll separating force (RSF) and a torque (C) are applied on the rolls to maintain pressure on the strip and to reduce its thickness. A rear tension (RT) and a...
Figure 6 shows the strip profile under different 1st IMR taper and shift, the taper slope is 10, the taper length is 230 mm, and the shift is changed in Fig. 6 (a); the taper length is 230 mm, the ...
Sendzimir Mill (Z Mill) In a Sendzimir mill (also called a Z mill), steel is rolled in a 20high roller configuration, which applies higher roll pressure and allows very hard and elastic materials to be rolled. Temperature monitoring ensures the steel is cooled sufficiently that it will not stick to and burn the separating paper when coiling.
In practice, for a 72 inch wide rolling mill, the Sendzimir mill has a maximum work roll diameter of about 4 inches. A four high mill, on the other hand of the same 72 inch width, would have a minimum work roll diameter of about 20 inches. ... Housing construction for cluster type cold rolling mills 1979.
