| titleOfInvention | High silicon steel sheet and manufacturing method thereof |
| abstract | The high silicon steel sheet excellent in electrical characteristics, which is one aspect of the present invention, includes a silicon diffusion layer whose silicon content decreases from the top to the bottom in the top and bottom surfaces of the silicon steel sheet. In another aspect of the present invention, there is provided a method of manufacturing a high silicon steel sheet having excellent electrical characteristics, comprising the steps of: preparing a silicon steel sheet; Coating Fe and Si nanoparticles on the upper and lower surfaces of the silicon steel sheet to form Fe and Si coating layers; Temper rolling a steel sheet on which Fe and Si coating layers are formed on the upper and lower surfaces; And subjecting the tempered and rolled silicon steel sheet to diffusion heat treatment to form a silicon diffusion layer whose silicon content decreases from the surface toward the inside. |
