摘要： In order to provide a very low iron loss, it is necessary to render the surface of a steel sheet smooth (specular). In the present invention, this is effected in a finish annealing furnace to simultaneously attain a high magnetic flux density and a specular surface. Specifically, after the completion of decarburization annealing, a steel material is pickled to remove an oxide layer present on the surface of the steel sheet, coated with an annealing separator comprising a substance nonreactive or less reactive with SiO.sub.2 and then subjected to finish annealing to provide a grain oriented electrical steel sheet having a specular surface. Magnetic domain division and tension coating of the steel sheet can provide a low iron loss value. In the finish annealing, since no time is required for dehydration, the annealing time can be shortened.

摘要： The present invention, in a method to produce a grain-oriented electrical steel sheet, proposes conditions for stable production by clarifying the causes by which secondary recrystallization is rendered unstable when primary recrystallization is controlled by raising the heating rate of decarburization annealing. The primary recrystallization structure is controlled by changing the heating rate and the oxide layer of a steel sheet is controlled by changing the conditions of soaking annealing in the decarburization annealing. The composition of the (Al, Si)N inhibitor is also controlled in the nitriding treatment thereafter.

摘要： In order to improve the adhesion property of an electrical steel sheet with no film of inorganic mineral matter on its surface, especially with respect to a tension-imparting insulating film, anodic electrolysis in an aqueous solution of silicate is carried out before insulating film formation to form a silicic film excellent in adhesion property with respect to the insulating film in a thin and strongly attached condition on the steel sheet surface. By this, a tension-imparting insulating film can be formed on a grain-oriented electrical steel sheet with excellent adhesion property to reduce the iron loss of the oriented electrical steel sheet. Also in the case of an insulating film that is not of the tension-imparting type, enhancement of film heat resistance and improvement of insulating property by increasing a film thickness are possible.
