Abstract (en)
[origin: WO03068451A1] The invention relates to a method for the post-treatment of single high-grade steel blanks which have been produced from deep-drawable circles or sections of high-grade steel by means of deep-drawing, pressing, rolling and deformation. According to the invention, the completed blanks are post-treated directly after being produced, in a drum which is hard-faced with hard granulate particles and moves in a rotating manner. In this way, changes in the surface of the single high-grade steel blanks produced, caused by material stresses occurring during the production process, are avoided, providing said high-grade steel blanks with an optimum appearance.
