Normally the surface of aluminum sheet is not textured but has a mill finish (MF). When an aluminum sheet is finished by a pair of specific rolls with surface textures produced by electrical discharge texturing (EDT) technique the textures are transferred from the rolls to the sheet producing the so-called EDT sheets.

This study investigated the surface roughness characteristics of rolls textured using the Shot-Blast Texturing and Electro-Discharge Texturing methods. The rolling tests were carried out in an actual cold rolling mill tandem line, and the surface roughness transferred from the roughened rolls to the material with these two methods was examined. The study measured and …
Mill rolls finished by electrical discharge texturing (EDT) are widely used in the manufacture of steel and aluminium alloy sheet / strip. Appropriate selection of process operating parameter levels: peak current, onloff time, polarity, etc., allows a limited degree of independence in specifying roll surface topography in
Surface texturing has brought significant improvements in the functional properties of parts and components. Sinker electro discharge machining (SEDM) is one of the processes which generates great texturing results at different scale. An electrode is needed to reproduce the geometry to be textured. Some geometries are difficult or impossible to achieve on an …
But it is a dream made true thanks to the PDT™ (Pomini Digital Texuring™), a technology developed for surface texturing of rolling mill work rolls. A simple digital process, based on modern fiber-optic laser heads, allows unparalleled wider range of surface possibilities in comparison to any other existing texturing technology, both in the ...

The modification of the surface topography of rolling mill rolls commonly results in a random surface texture pattern using, for example, sandblasting or …
Using EDT instead of other traditional texturing methods gives us greater precision and control over the final product. Rockport Roll Shop's EDT process produces improved consistency from roll to roll, higher peak count, lower waviness, and better strip control. It also reduces the influence of roll hardness on the final roughness of the roll.
Jorge et al. [14] analysed that texture of the AISI D2 Sendzimir rolls called as electrical discharge texture (EDT) hardened surface by using TiC/WC/Co and …
A low cost electrical discharge texturing machine which can texture work rolls having a broad range of diameters and lengths either on a production or research and development basis. The machine is relatively portable, for example, it can be mounted on a palate, and can be used at any location having an adequate electrical supply.
Elkoca pointed out that texturing of the rolling mill roll allows obtaining rolled products with a pre-defined texture thus ensuring more uniform ... machine model Melo P36, wheel rotation of 3000 rpm. Texturing of the specimens was carried out by electrical discharge texturing (EDT), using a commercial equipment model Engemaq 440 MC ...
Crucial here is a specific roughness on the work rolls created by electric discharged texturing (EDT). Once it is applied to the roll barrel, this roughness transfers precisely onto the strip surface. Using EDT rolls ensures the required quality and durability of …
blasted finish mill rolls as compared to the steel surface in Figure 2, produced by EDT processed mill rolls. Electro-discharge texturing (EDT) involves the application of a pulsed electric field between a tool electrode and work roll, which results in tiny random sharp craters in the surface. Figure 1. Blasted Surface Finish in 3 -D
This paper investigates the correlation between strip surface roughness and the surface of a temper mill work roll. As the actual temper mill is used, this data will be adopted to another actual temper mill for the application and operation of this experiment. The conclusions are as follows: The electro-discharge texturing (EDT) roll has a homogeneous roughness …
EDT Texturing is process of creating a specified texture on the surface of the work roll for steel and aluminum mills. The uniform surface finish is obtained by the application of electric current. The EDT process consists of discharging a series of …
Currendy, shot blasting (SB), laser beam texturing (LBT) and electrical discharge texturing (EDT) are the three principal methods used to texture mill rolls, however, electron beam texturing (EBT) is being evaluated.
Traditionally, laser texturing of mill roller is using a rotating chopper for beam modulation and the output pulse rate is 10 kHz (Wan, 2008, pp.309-314). Texturing a roller with length of 1800mm and radius of 300mm will cost 132 minutes. In order to meet the industrial requirements and improve the surface quality of a textured roller

Currently, electrical discharge texturing (EDT) technique, one surface texturing method suitable for mass production, is being used to texture aluminum sheets for the applications in automotive industry. It has been widely accepted in industry that EDT improves the forming behavior of aluminum sheets due to better friction behavior.
Designed to provide fast and accurate real time results, using combined non-contact eddy current and ultrasonic technologies to detect surface and sub-surface flaws of hot and cold mill rolls. Mounted onto roll grinding equipment, Rollscan systems can be used during and after roll grinding activities to effectively detect and quantify surface defects such as roll…Continue …

per centimeter depend on the texture of rolling mill's finishing rollers, their wear and the degree of removal by the rolling mill. The research was carried out on heat-treated finishing rollers on the surface of which a controlled texture was created by changing the electro-discharge texturing (EDT) parameters.
Surface texturing (EDT & Mill Finish) Background: The established surface topographies for Al auto-sheet are Mill-finish and EDT (electric discharge texturing). Mill-finish is the standard surface used in N. America. Although Mill-finish is used in Europe, EDT is more common (particularly for outer panels).
rolls of the rolling mills. For roughening the rolls to prepare a distinct surface topography, there are several methods currently available: Shot Blast Texturing (SBT), Electron Beam Texturing (EBT), Electron Beam Texturing (EBT), Electrical Discharge Texturing (EDT), Laser Texturing (LT). The topology of the sheet surface is highly dependent ...
An intelligent, knowledge-based system (IKBS) for electrodischarge texturing (EDT) in a concurrent engineering (CE) environment, and based on object oriented techniques (OOT), is introduced.
