Introduction to Rolling Process 1.1 Definition of Rolling Process Rolling is the most important metal forming process. More than 95% of ferrous and non-ferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam,
FIGURE 13.3 Schematic illustration of various roll arrangements: (a) Two-high mill; if a two-high mill is used for thick but short workpieces, it will commonly roll a billet back and …
Thin strip rolling involves significant metal plasticity to produce a desired product. Iwamoto (2004), Stoughton & Yoon (2004) and Huh et al. (2004) were interested in dealing with the plastic deformation and plastic yi elding of steel, and its micro-mechanics. With the need for higher quality and productivity in cold strip mill,
In general in tandem cold rolling mill / two-stand cold reversing mill the stands can be of 4- high type or 6-high type (i.e., stands with 6 rolls). The single stand cold reversing mill process can be achieved (in particular for stainless steel) with stands of 20-high type also known as cluster mill or Sendzimir mill. Strip shape measurement system
In this paper, a mathematical model for a four-high mill is proposed to analyze the elastic deformation of the backup and work rolls, including their respective axial deflection and surface flatness. The contact pressure between the backup and work rolls and that between the work roll and foil are functions of the roll's position in the axial …
Increases metal strength – It also has the ability to increase the strength of the metal being processed, creating more durable and resilient products.; Enhances surface finish – Additionally, it enhances the surface finish of metals, resulting in a more aesthetically pleasing and higher quality end product.; Disadvantages of Cluster Rolling Mill. High …
Cold rolling process is a technique which is mostly applied for the production of smaller sized products with high strength, these products are achieved by including …
For example, ultra thin carrier foil (thickness range from 2 to 6um) and super low surface roughness foil (NPV series) are used to meet the application of high density packaging and IC substrate.
The rolling line is composed of cluster mills (X-Mill) specifically designed to roll foils of non-ferrous materials, ensuring a stable and highly efficient production. Start-up is expected in 2022. ... The X-Mill with intelligent shape control using Automatic Flatness Control is designed for ultra-thin strip and foil rolling. The rolls are ...
Foil rolling mill Thin-strip rolling mill Finish-annealing furnaces Transportation system Storage system Roll grinding shop ... Foil rolling is an aluminium-specific process. No other material can be rolled down to a thick-ness of 5 or 6 µm. Taking into consideration that
It is a process used to shape metal into a thin long layer by passing it through a gap of two rolls rotating in different directions (clockwise and anti-clockwise). ... The popular Sendzimir mill is a type of cluster mill with having 20 rolls. In all the mills having this configuration, there are only two rolls which are work rolls while all ...
Cluster mill is a typical solution: among several layouts proposed [5,8], Sendzimir mill or "20-high mill" is herewith investigated [Fig.l], to gether with a more compact version, …

processing are very important in order to produce thin foil (< 10 µm) without quality problems. In this study, the effect of casting operations such as melting, alloying, filtration, metal transfer, and casting as well as the ceramic material used are investigated with respect to the presence of pinholes and scratches in thin foil products.
The 316L ultra thin stainless steel foil production process is as follows: Cold rolling of thin stainless steel strip coils: The cold rolling of stainless steel is to further reduce the thickness of the hot rolled steel sheet and make it into a thin strip foil. It is divided into continuous cold rolling and batch cold rolling.
Four-high mills are used to produce wide plates and hot-rolled or cold-rolled sheets, as well as strip of uniform thickness. Specialty mills – Two types of specialty mills are used (Fig 8). These are cluster mills and planetary mills. The most common type of cluster mill is the 20-high Sendzimir mill.
A lot depends on what kind of mill you roll the foil on and the width of the sheet. The are two-high, four-high, zinsermer(s) mills and others used for rolling a thin product. The controling factor is the tension on the sheet during the rolling process. Thin foil products are rolled two thicknesses thick in the mill.

Aluminum foil rolling machine detailed description 1,Technical Parameter:(aluminum foil rolling machine) Aluminum alloy 1000,3000,8000 series Entry .
This is what we commonly called the original foil. 6, Foil rolling The original foil is cold-rolled into thin foil by a high-precision rolling machine. Aluminum can be rolled to minimum of 5μ. When rolling about 10μ or less, two overlapping rolling can be used. The original foil achieve the required thickness by rolling several times.
Reversing Foil Mill for ultra-thin copper foil. Our Solution: This X mill with Air Bearing Shape Meter (ABSM) and hot spot spray is first application in China. 6-micron thickness was achived early in the commissioning stage. This is the first copper foil mill to start commmercial production with 10 microns or less in China.
Cold rolling process is a technique which is mostly applied for the production of smaller sized products with high strength, these products are achieved by including cluster mills as shown in Fig. 3, it does not reduce the thickness as much as hot rolling [11].The considerations are met, when the metal pieces are "worked" at temperature …
The strip from the hot rolling mill is coiled for transport to the cold mill. Figure 2 – Single Stand Hot Mill [3] Figure 3 – Breakdown Mill /Hot Tandem Mill [3] Cold rolling. Cold mills, in a wide range of types and sizes are available; some are single stand, others 3 stand and some 5 stand (Figures 4 and 5).
Finish rolling of tight tolerance thin gauge stock – commonly a 4-HI mill or cluster mill; ... The rolls themselves reduce the materials thickness and in the process …
16 Basics of aluminium rolling mill technology More economical in terms of energy saving is the direct casting process into strips of 12 to 20 mm thickness in twin-belt casters with a …
The paper investigates the main issues of design and modeling of so-called cluster mills for cold rolling of thin and moderate thin steel products, by means of numerical tools. ... i.e. cluster mill layout [9], including several supporting and back rolls, coupling effects ... tools supporting process monitoring, was already experimented by ...
