Segmented Scribing Roller For Refining The Domain Structure Of Electrical Steels By Local Mechanical Deformation
view source
US Patent:

55883214, Dec 31, 1996
Filed:

Jun 26, 1995
Appl. No.:

8/494475
Inventors:

Ralph E. Snyder - Export PA
Dominic A. Sorace - Sarver PA
James G. Benford - Pittsburgh PA
Assignee:

Allegheny Ludlum Corporation - Pittsburgh PA
International Classification:

B21B 122
US Classification:

723662
Abstract:

A method and apparatus are provided for refining the domain wall spacing of a grain-oriented silicon steel sheet by mechanical scribing using a solid anvil roll and a scribing roller including scribing segments arranged side by side along an arbor. The arbor carries inflatable bladder ribs along the length of the arbor to provide uniform contact pressure exerted by scribing surfaces of the strip.
