Y. Yoshitomi et al., ULTRATHICK GLASSLESS HIGH-PERMEABILITY, GRAIN-ORIENTED SILICON STEEL SHEETS WITH HIGH WORKABILITY, Journal of magnetism and magnetic materials, 160, 1996, pp. 123-124
A high-permeability, grain-oriented silicon steel sheet of ultrathick
gauge 0.50 mm with better punchability, realized by the formation of a
n extremely thin glass film formed in the surface region, has been dev
eloped. The new product has almost the same core loss as conventional
grain-oriented steel sheet of 0.35 mm gauge, when used in the iron cor
es of large rotary machines.
