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.
Varying roll shapes, such as parallel, CVC and cambered can be easily textured. Integrated automatic roll loaders and roll shop management software provides texturing capabilities of +1000 rolls/month. The Advantages of Rolltex EDT Wide range of textures. Ra 0.5 to 12 µm Fast and efficient roll texturing, +1000 rolls / month
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.
Mill roll texturing using EDT. J Mater Process Technol 1994; 45: 207 ...
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.
Electro-Discharge Texturing (EDT) is a specialized texturing process that replaces shot blast and provides a superior surface texture on rolls prior to chroming. It produces consistent, repeatable surfaces with tight tolerances from 50-350 Ra, extremely uniform surface with little variance over the surface of the roll and superior textured ...
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.

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.

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.
Mark Nelson demonstrates how to create texture using a rolling mill.
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
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 ...
EDT technique is a kind of texture method to melt the material on the barrel by spark-discharge between the electrode and the barrel in the insulation liquid. The texture pattern has a random distribution.
EDT TEXTURING. Electro-Discharge Texturing provides high quality textured surface in a range of 1,5 to 10mm. Improved roll roughness consistency is achieved through high level process control of the EDT machine variables. Read more CHROME PLATING.

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 …

grinding) or electro-discharge texturing (EDT) of mill rolls that then impart the devel-oped finish onto the metal surface during the final rolling operation. Asia and Europe addi-tionally use laser beam texturing (LBT) or electron beam texturing (EBT) systems to in-duce a matte finish on mill rolls. The finish
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 …
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 …
The modification of the surface topography of rolling mill rolls commonly results in a random surface texture pattern using, for example, sandblasting or …
The term EDT (Electro Discharge Texturing) means generating texture by discharging electric charges on the roller's surface. It is a special procedure of preparing the working rollers with which the aluminium strip comes into contact during the cold-rolling procedure, which is known as the EDT transition.
roll. In the first stands of the tandem mill the work roll will be chrome plated after grinding to get higher hardness on the surface and get better performance results in the production. The last stand and also all work rolls for the skin pass have to be textured after grinding. These textured rolls give between 40% and 60% of the roughness to the
With texture ranges from Ra 0.5 to 12 µm, regardless of roll hardness, the most stringent requirements for coated and uncoated strip qualities can be satisfied Machines of various sizes and specifications operate continuously to provide textured rolls for Tandem, Temper, Skin pass, Sendzimir, reversing mills and speciality strip producers.
