CONTINUOUS WIRE DRAWING, ANNEALING AND PLATING METHOD AND DEVICE THEREFOR

摘要

PURPOSE:To make it unnecessary to use uselessly heat energy by reheating a metallic wire rod at the time of plating of a molten metal, by stopping the cooling of the metallic wire rod after annealing at about a temperature of a plating molten metal, when wire-drawing a metal to the wire rod and annealing it, and thereafter, executing the plating of the molten metal. CONSTITUTION:A metallic wire rod 1 of copper, iron, etc. is subjected wire drawing in an object diameter by a wire drawing machine 2, and subsequently, led into an annealing device 5, and heated and annealed by electric conduction by a feed sheave 6. Next, it is led into a cooling chamber 7 and cooled, it is cooled to about a temperature of a molten plating metal of Sn, Zn, solder, etc. to be melted and plated in the next time, and led into a melting and plating device 13 through an oxidation preventing box 10 of an inert gas atmosphere. The wire rod plated with a molten metal is cooled to room temperature by a cooling device 14. A temperature of the wire rod going into the melting and plating device 13 is as high as the molten plating metal, therefore, reheating is not required, and a molten plating metallic wire rod can be manufactured by use of a small quantity of heat energy.
