摘要

The present invention proposes a device constitution that can reliably carry out refinement of magnetic domains by high energy beam irradiation with a laser electron beam or the like even when the rate of movement of a grain oriented electrical steel sheet changes. This device to improve iron loss properties scans a high energy beam across the feed path of a grain oriented electrical steel sheet for which final annealing has been completed and irradiates the steel sheet surface with the high energy beam as the sheet moves refining the magnetic domains. In this device an irradiation mechanism for scanning the high energy beam in a direction perpendicular to the feed direction of the steel sheet is provided with a function for orienting the scanning direction such that the perpendicular direction is inclined to the feed direction at an angle based on the rate of movement of the steel sheet along the feed path.
