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.

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.

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 ...
