The present invention relates to a roll position setting method for appropriately setting the roll positions of a Sendzimir mill by use of a plurality of screw down devices. When highhardness materials to be rolled, such as stainless steel, are cold rolled, small diameter work rolls are adopted in a rolling mill.

Our Products T. Sendzimir would like to present all of the products and capabilities afforded to our current customers and to our potential new customers. 20High Mill Sendzimir's 20High Mills are unique in that they have a small, chockless work roll and a cluster roll configuration supported by the backing.
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
Presented is a new technique to model the static deflection of the rolling mill components and compute the strip thickness profile. The new method combines the conventional finite element method with analytical solid mechanics and is applicable to clustertype mill configurations such as the 20high Sendzimir mill.
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

Fives pursued a unique approach to use a similar process to stainless steel cold rolling. We designed a robust monobloc DMS 20Hi EcoMill for thin GIGA steel with the following results: Steel thickness: mm mm. Strip width: 800 mm 1,650 mm. Production capacity: 180,000 tonnes per year.
Sendzimir mill. [ ′sen·zə‚mir ‚mil] (metallurgy) A mill having smalldiameter working rolls, each backed by a pair of supporting rolls, and each pair of these supported by a cluster of three rolls; used for coldrolling wide sheets of metal to close tolerance.
The original Sendzimir mill, which is still oper ating in Poland, had two 4in. diam work rolls, each of which was supported by two backing shafts which rotated eccentrically in the saddle rings and opened or closed the mill. 124 Mill: On subsequent mills it was necessary to give a heavier backing capacity to make heavier reductions on the strip.

Sendzimir mills are generally used for rolling of stainless steel and nonferrous grades worldwide. these mills operate at speeds ranging from 500 MPM to 1000MPM. At such high speeds, it is very necessary that the material of rolls is very clean and free from inclusions and defects and should be of very good quality. DeeTee can make all sizes ...
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.
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.
Chatter is a common term for the intense, undesirable mill vibrations occurring in both hot and cold rolling. Its cost could be very high due to the reduced strip quality and equipment damage. Its ...
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.
Lower investment for highquality plants. 32/116. Automobiles and shipbuilding, aircraft and spacecraft technology, medical machines, architecture and household appliances the application fields for highquality steel strip seem almost unlimited. Danieli Wean United's cold rolling technology (4high and 6high) allows producers to achieve ...
Edgedrop 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 edgedrop control, and a Sendzimir mill is one of the most popular cold rolling mills for silicon strips. Thus, the mastery of edgedrop control behavior for silicon strip cold rolling with a Sendzimir mill is ...

In total, Sendzimir now has over 265 cluster mills to our credit as well as 55 ZHigh® mills and 16 Planetary mills in over 43 countries.
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 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 ...
