摘要:
Grain-oriented electrical steel sheet excellent in coating adhesion is provided. The steel sheet contains Si: 2 to 7% mass % and has a primary coating composed mainly of forsterite on its surface. A compound (A) containing one or more elements selected from among Ca, Sr and Ba, at least one rare earth metal, and sulfur is incorporated in the primary coating so as to reside in the interface layer between the primary coating and the steel sheet. As a result, occurrence of primary coating exfoliation at regions that are strongly worked during manufacture of a wound core transformer or the like is prevented.

A slab having a predetermined composition is heated to 1280° C. or more. The slab is hot-rolled to obtain a hot-rolled steel sheet. The hot-rolled steel sheet is annealed to obtain an annealed steel sheet. The annealed steel sheet is cold-rolled to obtain a cold-rolled steel sheet. The cold-rolled steel sheet is decarburization annealed to obtain a decarburization annealed steel sheet. The decarburization annealed steel sheet is coiled in a coil state. The coil-state decarburization annealed steel sheet is finish-annealed. The cold-rolled steel sheet is heated to a temperature of 800° C. or more at a rate of 30° C./sec or more and 100° C./sec or less during increasing temperature of the cold-rolled steel sheet in the decarburization annealing or before the decarburization annealing. The decarburization annealed steel sheet is heated at a rate of 20° C./h or less within a temperature range of 750° C. or more and 1150° C. or less during increasing temperature of the decarburization annealed steel sheet in the finish annealing.

摘要:
A coating solution for forming a flat-surface insulating film, which is a coating solution obtained by dissolving a poly(diorgano)siloxane A having a mass average molecular weight of 900 to 10,000 and a metal alkoxide B in an organic solvent C and further adding water, wherein the molar ratio A/B of the poly(diorgano)siloxane A to 1 mol of the metal alkoxide B is from 0.05 to 1.5, the organic solvent C has a hydroxyl group, the solubility of water in 100 g of the organic solvent C is from 3 to 20 g, and the molar ratio C/A of the organic solvent C to 1 mol of the poly(diorgano)siloxane A is from 0.05 to 100. This coating solution for forming a flat-surface insulating film ensures that an organic modified silicate composed of a poly(diorgano)siloxane and a metal alkoxide can be formed as a thick film having 1 μm or more and can be an organic modified silicate insulating film causing no irregularities due to phase separation and having a low Young's modulus and flexibility high enough to follow the deformation of a substrate board, as well as high film surface flatness allowing for mounting of microcomponents of an electronic device or the like.
