Concepts. Up to the limit ... The input stock from the casting plant or hot rolling mill is up to 16.0 mm thick and wound into loose coils with variable inner diameters. More Information Design for roughing and intermediate rolling in the same mill. Tandem cold mills for roughing and intermediate rolling are all-rounders. ...
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
In a rolling mill so constructed that top and bottom work rolls are bucked up by upper middle and upper buck-up rolls, and bottom middle buck-up rolls, respectively, and the adjustment of movement of the middle rolls in the axial direction is combined with the adjustment of bending of the work rolls to effect shape control of a plate material as rolled; a control device comprising …
–Reducing friction –Using smaller diameter rolls to reduce the contact area –Taking smaller reductions per pass (also to reduce the contact area) –Rolling at elevated temperatures to lower the strength of the material –Apply longitudinal tension to the strip during rolling –back tension on the pay-off reel or front tension on the take-up reel
CONCEPTS Achenbach foil rolling mills are four-high rolling mills designed for two different applications:. Universal foil rolling mills for all strip thicknesses from 0.7 mm to 0.006 mm for a wide range of rolled products; Specialised foil rolling mills for foil rolling lines for graduated strip thicknesses.; Specialised foil rolling mills come in three types:
Referred to as "ultra-thin rolling control," the system is essentially an adapted control concept that has been successfully applied many times in tandem cold mills. When rolling below a certain strip thickness, the control mode is switched from speed control to roll-gap control while the strip tension is kept constant.
Rolling is the most commonly used and the most efficient type of metal forming, which consists in deformation of metal by means of rotating rolls (Fig. 1.1, a, b, c ); 75-80% of the total
Rolling metalworking Wikipedia. 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 and to make the thickness uniform The concept is similar to the rolling of dough Rolling is classified according to the temperature of the metal rolled Most steel mills have rolling mill divisions that convert the …

Rolling Mill 5000, located in Kolpino, near Saint -Petersburg, produces thick plate for large diameter pipes, ship and bridge building and other industries. Read more. Izhora Pipe Mill. The mill in Kolpino specialises in manufacturing large diameter pipes from plate, which are produced at the nearby Kolpino Mill-5000.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

Also outside the mill stand itself, the entire rolling technology, like the advanced safety concepts, modern fume exhaust system, emulsion or rolling oil filtration, and the hydraulic equipment, is based on the experience of ANDRITZ Sundwig.
Basic concept of the rolling Rolling is a process used to shape metal into a thin long layer by passing it through a gap of two rollers rotating in different directions (clockwise and anti-clockwise). The gap between the two rollers is supposed to be smaller than the thickness of the work piece of the material to be formed.

Rolling mill simulator A new platform for testing, analysis and optimization of cold rolling mills. Axel Brickwedde, Frank Feldmann, Nicolas Soler The cold rolling of flat metal products especially in tandem or multi-stand mills is a highly complex process where the product quality is influenced by various aspects.
Apart from the capability of these known rolling mills to roll premium-quality pipe, plant concepts of this kind have a very high production capacity which ranges from 300,000 to 900,000 tons/year depending on the range of dimensions and on production time.
Z mill Wikipedia. A Z Mill or Sendzimir Mill is a machine for rolling steel 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
