Mill roll texturing using EDT ScienceDirect

1/9/1994· 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

Electrical Discharge Roll Texturing (EDT) Using Different

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 a Spark Tec dual voltage DC pulse generator and a Charmilles Robofil 200, employing a single high

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

Hard chromium plating of EDT mill work rolls

Hard chromium plating of cold mill work rolls is common practice in order to maintain topography and increase roll service life. The paper details the effect of hard chromium plating on electrical discharge textured (EDT) roll surface topography and surface integrity. Comparative data with corresponding non-chromium plated EDT roll samples are also presented and discussed. Irrespective of the

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.

Electro-Discharge Texturing (EDT) SMSgroup

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 surfaces on hard work rolls.
