Title:

方向性電磁鋼板の鉄損改善装置

Document Type and Number:

Japanese Patent JP5871013

Kind Code:

B2

Abstract:

Proposed is a device constitution that can reliably carry out refinement of magnetic domains by high-energy-beam irradiation with a laser beam, an electron beam, or the like even when the sheet passing speed of a grain-oriented electrical steel sheet changes. This device scans a high-energy beam in a direction traversing a feed path of a grain-oriented electrical steel sheet having subjected to final annealing so as to irradiate a surface of the steel sheet being passed through with the high-energy beam to thereby perform magnetic domain refinement, the device including an irradiation mechanism for scanning the high-energy beam in a direction orthogonal to the feed direction of the steel sheet, in which the irradiation mechanism has a function of having the scanning direction of the high-energy beam oriented diagonally, relative to the orthogonal direction, toward the feed direction at an angle determined based on a sheet passing speed of the steel sheet on the feed path.
