May 30, 2015· (Suggested Rolling Mill is not the one in the video, but is a less inexpensive option, which is good for beginning jewelers.) In this video, Prof. John Ahr introduces you to the Rolling Mill.
EDT rolling transfers this exact finish onto the strip during the final rolling pass. 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.
grinding) or electrodischarge texturing (EDT) of mill rolls that then impart the developed finish onto the metal surface during the final rolling operation. Asia and Europe additionally use laser beam texturing (LBT) or electron beam texturing (EBT) systems to induce a matte finish on mill rolls.
Currently, 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 ...

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
As stated in a previous post I love to make hollow forms. This requires a lot of different surface patterns. In this post I am offering some suggestions on texturing metal using the rolling mill. glue heavyduty paper plate shapes to metal for rolling mill How to texture metal with a rolling mill Texture .
blasted finish mill rolls as compared to the steel surface in Figure 2, produced by EDT processed mill rolls. Electrodischarge 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.
Roll Surface Technologies (RST) provide hard chrome plating, steel / polyurethane / rubber roll grinding, electro discharge ( EDT) roll texturing, chock maintenance and inspection as well as a diverse range of other services such as plant maintenance, roll turning and repair, and in plant coil logistics solutions.
It produces consistent, repeatable surfaces with tight tolerances from 50350 Ra, extremely uniform surface with little variance over the surface of the roll and superior textured surfaces on hard work rolls. Using proprietary EDT equipment, designed, and manufactured by SMS group, we can uniformly texture the entire roll surface with no gaps ...

Summary. The paper gives the results of a series of tests aimed at evaluating the effect of the electrical discharge texturing (EDT) process on the surface integrity of mill work rolls using two different electrical generator and dielectric flushing arrangements.
Traditionally, laser texturing of mill roller is using a rotating chopper for beam modulation and the output pulse rate is 10 kHz (Wan, 2008, ). 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
Sep 30, 2002· The paper details experimental research on the surface modification/alloying and combined electrical discharge texturing (EDT) of hardened AISI D2 Sendzimir rolls, used for the production of stainless steel strip. Test results are presented when using powder metallurgy (PM) green compact and sintered electrodes—TiC/WC/Co and WC/Co, as a means to improve roll life and .
