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· Rolling trials showed the potential improvement of using mill rolls EDT textured using PM tool electrodes. Roll/strip texture transfer data showed that both the R a and P c transfer ratios were consistently higher for the TiC/WC/Co textured rolls indicating less roll wear.
Rolling Mill Textures On Metal Thursday, January 23, 2014 I had another play with my rolling mill last week using some of the texture sheets from Etsy shop Rolling Mill Resource. I used some sterling silver and copper sheet and soon discovered it''s best to get organized before you start! ... If there''s too much resistance you make the gap ...
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 ...
can be a fair assumption since the micropockets generated by EDT rolls on the sheet metal surface are . ... Wise M L H and ElMenshawy M F 1994 Mill roll texturing using .
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.

EDT technique is a kind of texture method to melt the material on the barrel by sparkdischarge between the electrode and the barrel in the insulation liquid.
Currently, shot blast texturing (SBT), electric discharge texturing (EDT), electron beam texturing (EBT) and laser texturing (LT) are the three principal methods used to texture mill rolls. Many mills use these methods currently. However, conventional methods for texturing the mill rollers used in the cold rolling of automotive sheet steel have ...
Sarclad Rolltex machines deliver a fast and reliable process to provide surface textures on cold mill rolls to outstanding accuracy and consistency. This achieved with lower operating costs and improved environmental conditions compared to other texturing processes such as shot or grit blasting.
Mill roll texturing using EDT. ... (EDT) are the three principal methods used to texture mill rolls, however, electron beam texturing (EBT) is being evaluated. Although widely used, conventional SB has major limitations due to the lack of adequate process control and its inability to deal with hard alloys. The paper discusses the techniques now ...

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
Mill roll texturing using EDT The surface texture of sheet steel of the type used for automotive applications plays an important role during subsequent processing operations. With textured s
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 ...
Chrome Deposit Corporation''s EDT Texturing machines are capable of texturing a roll face up to 84″, diameter up to 32″ and roll weight up to tons. Only Chrome Deposit Corporation EDT delivers lasting consistency, elevated productivity and the highestquality end .
1. Introduction. Industrial experience with hardchromium plated mill rolls, clearly indicates that coatings applied to a particular type of roll surface texture achieved either by shot blasting (SB), electrical discharge texturing (EDT) or laser beam texturing (LBT), extend roll service life and performance.
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.
