Patent Number Title Of Patent Date Issued
5961744 Grain oriented silicon steel sheet having low core loss and method of manufacturing same October 5, 1999
Grain oriented silicon steel sheet on which is formed an insulating coating having a thickness that is not less than 2.5 .mu.m that imparts tension to the steel sheet which does not have an inorganic mineral layer formed during a final annealing step (glass film) and a method of forming
5782998 Grain oriented electrical steel sheet having specular surface July 21, 1998
In order to provide a very low iron loss, it is necessary to render the surface of a steel sheet smooth (specular). In the present invention, this is effected in a finish annealing furnace to simultaneously attain a high magnetic flux density and a specular surface. Specifically, after t
5753051 Oriented electrical steel sheet having low core loss and method of manufacturing same May 19, 1998
Low core loss oriented electrical steel sheet having a surface coating that has a Young's modulus that is not less than 100 GPa and a differential of thermal expansion coefficient relative to the sheet base metal that is not less than 2.times.10.sup.-6 /K and which contains not less than
5679177 Oriented electrical steel sheet having low core loss and method of manufacturing same October 21, 1997
Low core loss oriented electrical steel sheet having a surface coating that has a Young's modulus that is not less than 100 GPa and a differential of thermal expansion coefficient relative to the sheet base metal that is not less than 2.times.10.sup.-6 /K and which contains not less than
5565272 Grain oriented silicon steel sheet having excellent primary film properties October 15, 1996
A grain oriented silicon steel sheet having excellent primary glass film property and magnetic property, comprising 2.0 to 5.0% by weight of Si, wherein a primary glass film formed during secondary recrystallization annealing is composed mainly of forsterite (Mg.sub.2 SiO.sub.4) and an
5411808 Oriented electrical steel sheet having low core loss and method of manufacturing same May 2, 1995
Low core loss oriented electrical steel sheet having a surface coating that has a Young's modulus that is not less than 100 GPa and a differential of thermal expansion coefficient relative to the sheet base metal that is not less than 2.times.10.sup.-6 /K and which contains not less than
