NICKELLED STEEL SHEET PROOFED AGAINST TIGHT ADHESION DURING ANNEALING AND PROCESS FOR PRODUCTION THEREOF |
摘要 |
It is planned to prevent adhesion of nickel plated steel sheets with each other , which is apt to occur during producing a steel sheet in which nickel is diffused by heat treatment of a nickel plated steel sheet in an annealing furnace. A nickel plated steel sheet having a nickel-iron diffusion layer as a thickness of 0.5-10 mm, a nickel plated layer thereon as a thickness of 0.5-10 mm, and a silicon oxide layer thereon as an amount of silicon of 0.1-2.5 mg/m @ which are formed on at least one face of a cold rolled steel plate. After nickel is plated on a cold rolled steel plate, silicon hydrate is precipitated by dipping or electrolysis treatment in a bath of sodium orthosilicate as a main component, followed by heat treatment. <IMAGE> |
