摘要： A heat-resistant magnetic domain refined grain-oriented silicon steel, a single-sided surface or a double-sided surface of which has several parallel grooves which are formed in a grooving manner, each groove extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel, and the several parallel grooves are uniformly distributed along the rolling direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. Each groove which extends in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel is formed by splicing several sub-grooves which extend in the width direction of the heat-resistant magnetic domain refined grain-oriented silicon steel. The manufacturing method for a heat-resistant magnetic domain refined grain-oriented silicon steel comprises the step of: forming grooves on a single-sided surface or a double-sided surface of a heat-resistant magnetic domain refined grain-oriented silicon steel in a laser grooving manner, a laser beam of the laser grooving is divided into several sub-beams by a beam splitter, and the several sub-beams form the several sub-grooves which are spliced into the same groove.

摘要： Disclosed is a manufacturing method for a high silicon grain oriented electrical steel sheet, the silicon content of the high silicon grain oriented electrical steel is greater than 4 wt %, comprising the steps of: (1) performing decarburization annealing of a cold-rolled steel plate; (2) allowing high silicon alloy particles in a completely solid state to collide at a high speed with the surface of the decarburization annealed steel plate to be sprayed, thus forming a high silicon alloy coating on the surface of the steel plate to be sprayed; (3) coating a release agent and drying; and (4) annealing. The manufacturing method for the high silicon grain oriented electrical steel sheet of the present invention is inexpensive, and, the high silicon grain oriented electrical steel sheet produced is of stable quality and is provided with great magnetic performance.

摘要： A manufacturing method for low-magnetostrictive oriented silicon steel is provided, wherein the oriented silicon steel comprises a silicon steel substrate and an insulating coating on the surface of the silicon steel substrate. The manufacturing method comprises: performing single-sided laser etching on the silicon steel substrate, wherein the side of the silicon steel substrate, on which single-sided laser etching is performed, is a first surface, and the side opposite to the first surface is a second surface; determining a deflection difference between the first surface and the second surface based on the power of the laser etching, and determining a difference in the amount of the insulating coatings on the first surface and the second surface based on the deflection difference; and forming insulating coatings on the first surface and the second surface. The amount of the insulating coating on the second surface is greater than that on the first surface, and the amount of the insulating coating on the first surface and that on the second surface satisfy the difference in the amount of the insulating coatings. By using the manufacturing method in the present invention, the problem of a relatively large magnetostrictive deviation between two sides of oriented silicon steel caused by single-sided laser etching can be solved. Oriented silicon steel manufactured by the aforementioned manufacturing method is also provided. A transformer iron core prepared using the oriented silicon steel enables a transformer to have low noise during operation.
