摘要:
A zinc or zinc alloy coated steel sheet has a surface-treatment film formed thereon in a coating weight per one surface of 100 to 600 mg/m2. The surface-treatment film is obtained by applying, onto a surface of the zinc or zinc alloy coated steel sheet, the surface-treatment solution prepared by mixing the following components at specific ratios, the surface-treatment solution having pH of 8 to 10: a silane compound (A) having a hydrolyzable group, obtained from a silane coupling agent (a1) having a glycidyl group, a tetraalkoxysilane (a2), and a chelating agent (a3); a zirconium carbonate compound (B); a vanadate compound (C); a nitric compound (D); and water, and by subsequently heating and drying the surface-treatment solution thus applied.

An ironing apparatus includes an ironing die and an ironing punch, an injection port for injecting gas or liquid to the metal plate at a high pressure to remove substance adhered to the metal plate therefrom, a suction port for sucking the adhered substance removed from the metal plate, and a protrusion mount portion with a protrusion for preventing dispersion of the gas or the liquid. An ironing method for ironing the metal plate having the single surface or both surfaces coated with the organic resin film includes the steps of injecting the gas or the liquid from the injection port to the metal plate at the high pressure to remove the adhered substance from the metal plate, and sucking and collecting the adhered substance removed from the metal plate from the suction port. The adhered substance such as the hair may be removed by the aforementioned invention.
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.
