摘要： An electrical steel sheet provided with insulating coating excellent in punchability and adhesion property is obtained.
The electrical steel sheet provided with insulating coating comprises an electrical steel sheet and an insulating coating formed on the electrical steel sheet. The insulating coating contains Si and Fe. The coating weight of Si in the insulating coating in terms of SiO 2 is 50% to 99% of the total coating weight. The ratio (Fe/Si) of the content of Fe to the content of Si in the insulating coating ranges from 0.01 to 0.6 on a molar basis. The insulating coating preferably contains an organic resin and/or a lubricant. In the insulating coating, the ratio (C (the organic resin + the lubricant)/(Fe 2 O 3 + SiO 2 )) of the coating weight of the organic resin and/or the lubricant in terms of C to the sum of the coating weight of Fe in terms of Fe 2 O 3 and the coating weight of Si in terms of SiO 2 preferably ranges from 0.05 to 0.8.-

摘要： An electrical steel sheet with an insulation coating excellent in punchability, coating adhesion property and coating film property after annealing, even without containing any chromium compound in the insulation coating. The insulation coating is formed by applying a surface-treatment agent to at least one side of the electrical steel sheet and drying the surface-treatment agent. The surface-treatment agent contains trialkoxysilane and/or dialkoxysilane (A) in which a substituent bound to Si is constituted only by at least one non-reactive substituent selected from the group consisting of hydrogen, an alkyl group, and a phenyl group; and a silane coupling agent (B), at a mass ratio (A/B) of 0.05 to 1.0.
