| description | PURPOSE: To produce a silicon steel sheet excellent in property of reducing iron loss and noise by specifying the width of a linear groove, the spacing between linear grooves, the speed of collision with a steel sheet, and the depth of grooves, respectively, at the time of providing the grain oriented silicon steel sheet with linear grooves at spaces. CONSTITUTION: A finish-annealed grain oriented silicon steel sheet S is passed in the direction of an arrow. Projecting teeth 2, orthogonal to a sheet passing direction, are provided, at spaces, onto a press main body 1, and the projecting teeth 2 are advanced and retreated to and from the steel sheet S at high speed by a driving device 3, by which compressive linear grooves are formed in the sheet surface. At this time, the width of the projecting tooth 2 forming the linear groove, the spacing between the teeth, the speed in a sheet direction of the projecting teeth 2 when the teeth get contact with the steel sheet S, and the depth of the grooves are specified to 1-50μm, 1-6mm, |
