Embodiment

[0062] Hereinafter, the effects of the present invention will be specifically described with reference to Examples and Comparative Examples of the present invention. In this embodiment, first, (A1) after degreasing and pickling the steel base material (steel plate) with a thickness of 0.17 mm to 0.23 mm after cold rolling, annealing and pressure adjustment, a Watts bath is used on both surfaces thereof. Ni plating is performed, or (A2) Ni plating is performed on both sides of a cold-rolled steel substrate (steel plate) with a thickness of 0.17 mm to 0.23 mm using a Watt bath, followed by annealing to form a Ni diffusion layer, followed by degreasing and pickling , to produce a Ni-plated steel plate.

[0063] Next, a Zr film, a phosphoric acid film, and / or a phenolic resin film were formed on the surfaces (both sides) of the Ni-plated steel sheet produced by the above method (A1) or (A2) by the method shown below.

[0064] (B1) The Ni-plated steel sheet produced by the method ...

Abstract

The invention provides a steel plate for container and a manufacturing method thereof. A steel substrate has on at least one surface thereof a Ni plating layer containing 150 mg / m<2> to 1,000 mg / m<2> of Ni. A phosphoric acid coating of 0.1 mg / m<2> to 100 mg / m<2> in terms of P content and at least one of a Zr coating of 0.1 mg / m<2> to 500 mg / m<2> in terms of Zr content and a phenol resin coating of 0.1 mg / m<2> to 100 mg / m<2> in terms of C content are formed on the Ni plating layer by a cathode electrolytic treatment.

Description

technical field [0001] The present invention relates to a steel plate for containers that is used as a material for can making and processed into various metal containers such as beverage containers and food containers, and a manufacturing method thereof. [0002] This application is based on Japanese Patent Application No. 2006-244560 and Japanese Patent Application No. 2007-069271, and uses their contents. Background technique [0003] Metal containers used for beverages or foods are roughly classified into two-piece cans and three-piece cans. For example, when manufacturing two-piece cans represented by DI (Drawing-Ironing, drawing-drawing) cans, after drawing-drawing processing, the inside of the can is painted, and then the outside of the can is painted. Packaging and printing. On the other hand, when manufacturing a 3-piece can, the surface corresponding to the inner surface of the can is painted, and the surface corresponding to the outer surface of the can is print...
