It is offered the technology of electric discharge treatment in the impuls regime of the cast rollers working surface, which, from one side, allows to create on the surface of treatment mikrorelef with the prescribed parameters of roughness, and, with other, to give the substantial consolidating for the superficial layer of metal for the workshops of steel bar cold rolling and strip of a number of metallurgical plants of NIS countries. It is developed, made and passed the successful industrial tests the universal equipment for realization of the developed technology. Possibility of the choice of treatment regimes for surface rollers in the wide range of electric parameters allows due to the receipt of rational values of roughness and compactness of microbulges on the bar surface to secure a minimum expense of coverages materials with high their quality.
