Abstract

PURPOSE: To obtain a copper-plated steel plate free of decoloration due to oxidation by greatly shorting the process of the conventional method by the procedure in which copper is plated on a steel plate subjected to cold rolling, deoiling, and annealing and then washed with water, and the steel plate is immediately coated with a benzotriazole aqueous solution of a fixed concentration.
CONSTITUTION: A steel plate, subjected to cold rolling, deoiling, and annealing, is sent to a horizontally continuous copper plating line for copper plating, then washed with water immediately after copper plating, and then coated with a 0.1W1wt% benzotriazole aqueous solution kept at 40W60°C to form the molecular film of water- insoluble benzotriazole-copper (II), whereby obviating the needs for the coating of a baking inhibitor and the removal of the inhibitor. Thus, a copper-plated steel plate enabling the manufacture of double pipe used in cars, etc., free of decoloration due to oxidation can be obtained inexpensively. Also, because the conventional chromic acid is not used, annealing before plating can be omitted and pollution problem can be eliminated.
