• Mill roll texturing using EDT ScienceDirect

    01/09/1994· EDT, LBT and EBT have significant advantages over SB not least in that roll surface texture can be accurately specified in advance and consistent results obtained between rolls, a very important feature, as textured rolls work in pairs in the mill. While all three non-traditional methods are capable of "industry acceptable" textures, that produced by EDT differs from the other two in that the

    Mill roll texturing using EDT ScienceDirect

    The paper discusses the techniques now available for roll texturing, the developments that have occurred over the last decade and the main advantages provided by EDT over traditional SB methods. The results of an extensive series of tests aimed at evaluating operating variables when texturing steel work rolls using EDT are presented. Test parameters included peak current, on/off-time

    EDT rolling SMS group

    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. Using EDT rolls ensures the required quality and durability of the color coatings on the exposed parts. Also

    30/08/1999· 1.. IntroductionIndustrial experience with hard-chromium 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

    EDT and Flash Chrome Plating Rockport Roll Shop

    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.
