ABSTRACT:
An apparatus for scribing grain-oriented silicon steel to improve the core loss thereof is provided. The method comprises passing the final gauge steel after cold rolling through a roll pass defined by an anvil roll and a scribing roll having a surface with a plurality of projections thereon with said projections being generally in a direction of the roll axis; the anvil roll is constructed from a material that is relatively more elastic than the material from which said scribing roll is constructed. Preferably the scribing roll is constructed from steel and the anvil roll is constructed from rubber.
