Title:
ORIENTED SILICON STEEL PLATE FOR LOW CORE LOSS AND HIGH FLUX DENSITY AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH06188116
Kind Code:
A
Abstract:
PURPOSE: To provide an oriented silicon steel plate for low core loss and high flux density.
CONSTITUTION: An oriented silicon steel plate for low core loss and high flux density contains 1-7% Si, 0.03-0.15% P, and, if necessary, 0.02-0.20% Sn. On the surface of the steel plate, grooves whose average maximum depth is 2-50μm and which have forsterite left behind on parts of the bottom are made at intervals of 45-90° from the longitudinal direction of the steel plate. This silicon steel plate has a primary film mainly composed of forsterite of the average thickness of 0.3μm or smaller and whose core loss W17/50 is 0.70Watt/kg or lower.
