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： 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.
