Abstract

Procedure for separating wustite scale from an iron or steel product, characterized in that it comprises the steps of feeding sharp-edged grains in a centrifugal blasting wheel; spin the blast wheel at low speed; project the sharp-edged grains at a non-perpendicular angle against the product; and use the edges of the sand grains to clean the scale of wustita.
