摘要： A grain-oriented electrical steel sheet includes: a base steel sheet; a primary film formed on a surface of the base steel sheet; and a tension insulation coating formed on a surface of the primary film, in which a magnetic domain control is performed by irradiating the tension insulation coating with a laser from above. When a strip-like sample having a length of 300 mm in a direction parallel to a rolling direction of the grain-oriented electrical steel sheet and a length of 60 mm in a direction parallel to a transverse direction is extracted from the grain-oriented electrical steel sheet, a range from a surface of the tension insulation coating to a depth position of 5 µm toward the base steel sheet side from an interface between the base steel sheet and the primary film is removed by pickling at least one surface of the sample, and a warpage amount of the sample is thereafter measured, the warpage amount satisfies predetermined conditions.

摘要： The purpose of the present invention is to prevent, when joining end faces of a plurality of soft-magnetic material plates which are overlapped in a plate thickness direction and are bent at a portion forming a corner part of a core, the position of the end faces from being displaced from a desired position. In the region of a window part which is the region inside a first portion 110 and a second portion 120, a third portion 130 of which the length in the longitudinal direction (X-axis direction) is the same as the length of the window part in the X-axis direction at the position in which the third portion 130 is disposed is disposed so as to contact a region of an inner peripheral surface between a first corner part 101 and a third corner part 103.

摘要： The object of the present invention is to provide a low iron loss and low noise grain-oriented electrical steel sheet for securing both low core loss and low noise of a transformer at the same time. The present invention relates to a grain-oriented electrical steel sheet containing Si: 1.0 - 4.0 wt% produced by controlling with regard to epsilon o, which is defined as a 0-p value when a grain-oriented electrical steel sheet is magnetized up to a saturated magnetic flux density, and epsilon 17, which is defined as the value obtained by subtracting a 0-p value at the magnetization magnetic flux density of 1.7 T from a 0-p value at a saturated magnetic flux density, epsilon OC and epsilon 17L, which are absolute values deviated by forming a tension film and a forsterite film, and epsilon OL and epsilon 17L, which are absolute values deviated by irradiating laser after the film formation, in adequate ranges respectively, and further controlling lambda 17, which is a 0-p value at the magnetization magnetic flux density of 1.7 T, in the most appropriate range, when measuring a 0-p value of magnetostriction vibration in the rolling direction.

摘要： This wound core is configured by stacking a plurality of bending-processed bodies upon each other in a sheet thickness direction thereof, the bending-processed bodies being formed from a directional magnetic steel sheet having phosphorus-containing coating formed on a surface thereof. The bending-processed bodies are formed in a rectangular shape, each having four planar portions and four corner portions adjacent to the planar portions. The corner portions include a flexed area in which, as viewed laterally, a sum of bending angles is substantially 90°. As viewed laterally, the number of deformation twins present in the flexed area is not more than five per mm of a length of a central line in the sheet thickness direction in the flexed area. The amount of phosphorus eluted from the corner portions when boiled in water for 30 minutes is not more than 6.0 mg per m
