Sep 01, 1994·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.
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. Investigations were conducted using both aSpark Tec dual voltage DC pulse generator and a Charmilles Robofil 200,employing a single high-density fine grain graphite tool electrode.Get Price
Once it is applied to the roll barrel, this roughness transfers precisely onto the strip surface. Using EDT rollsensures the required quality and durability of the color coatings on the exposed parts. Also engineered by SMS group is a feature to handle the low rolling forces in the finishing pass: our extended bending system (EBS). The EDT rolling stand is highly versatile.Get Price
Rolltex EDT. SarcladRolltex 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. Advanced electronic control provides independent selection of surface roughness (Ra) andPeak Count (PC) values…Get Price
EDTrolling transfers this exact finish onto the strip during the final rolling pass. Crucial here is a specific roughness on the workrollscreated by electric dischargedtexturing(EDT). Once it is applied to therollbarrel, this roughness transfers precisely onto the strip surface.Get Price

Using EDTinstead of other traditionaltexturingmethods gives us greater precision and control over the final product. RockportRollShop’sEDTprocess produces improved consistency fromrolltoroll, higher peak count, lower waviness, and better strip control. It also reduces the influence ofrollhardness on the final roughness of theroll.Get Price
