Abstract
A grain oriented silicon steel strip is flattened by a skin pass rolling to flatten undulations caused by scribe lines imparted to the strip for mechanically refining the magnetic domain wall spacings.
Claims11
A method of providing a flattened surface on final texture annealed cube-on-edge grain-oriented silicon steel strip having a refined magnetic domain wall spacing by mechanical scribing formed by a multiplicity of closely spaced scribe lines extending generally transversely across the width of the strip forming localized undulations to the strip surface, the method comprising skin pass rolling the domain refined strip with rolling pressure sufficient essentially only to flatten undulations due to said scribing.
