Easytomodify a conventional 4high or 6high mill into Zhigh mill. Structural figure Sendzimir ZWiper Feature of Sendzimir ZWiper Small diameter wiper roll achieves good strip wiping. Widthwise uniform wiping is realized, because each wiper roll supported by axially divided supporting rollers gives uniform pressing force onto strip.
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.
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

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.
Implementation of a Simple System to Change Wiper Roll Blocks in Sendzimir Mills Challenge The objective of this project is to change in Sendzimir mills, quite simply, the upper wiper roll blocks (Pollastrelli system) in a safe way, avoiding the risk of occupational accidents, making easier and less tiring work for the operator. Action

Abstract: A crown adjustment system for a 20high (1234) cluster mill of the type having upper and lower clusters each comprising a work roll, two first intermediate rolls, three second intermediate rolls, and four backing bearing assemblies. Each of the backing bearing assemblies of the upper cluster comprises a shaft supported along its ...
The method provides a method for improving the residual emulsion on the surface of band steel rolled by a sendzimir rolling mill. The technical parameters before, after and in the band steel rolling process are as follows: before rolling, a wiping roller of the rolling mill is ground and mounted, the roughness Ra of the wiping roller is set to be microns, and the elevation of a coarse ...
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 ...
A simulation model for predicting the shapes of coldrolled strips in 20high Sendzimir mills was developed, and its predicting accuracy was assessed experimentally. By this model, improvement of quarter buckles was shown difficult merely by conventional shape control actuators,, lateral shifts and taper profiles of first intermediate rolls, roll crowns of work rolls and second ...
Rolling mill system consists of several mills and the strip to be rolled passes between the mills to control the thickness and shape in hot and cold rolling [1] [16], which affects the quality of ...
The device consists of three rollers, between which the strip passes, where each roller is supported by a plurality of pairs of casters, the caster pairs being spring mounted in a pair of frames,...
Sendzimir mill was not carried out, so it is impossible to quantitatively analyze the main sources of silicon strip edge drop in the Sendzimir mill. During the rolling process of the Sendzimir mill in actual production, the transverse thickness deviation of the coldrolled silicon strips cannot meet the customers' requirements after trimming,

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.
The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best combination of opening parameters was obtained.
