ABSTRACT:
A method for manufacturing a zinc wire includes the following steps: (1) casting a molten zinc ingot into a zinc rod; (2) annealing the zinc rod by heating the zinc rod at a temperature of 250.degree. C.-310.degree. C. for more than 30 minutes, and then cooling the zinc rod to room temperature; (3) extruding the annealed zinc rod at a temperature of 250.degree. C.-310.degree. C. to form a zinc bar; (4) air cooling the zinc bar to room temperature after step (3); (5) immersing the cooled zinc bar into a liquid having a boiling point of about 100.degree. C.-150.degree. C.; (6) heating the liquid at its boiling point for a predetermined period; (7) subsequently removing the zinc bar from the liquid, and then baking and drying the zinc bar; (8) forming the baked zinc bar into a rough zinc wire by continuous rolling; (9) subjecting the rough zinc wire, after rolling, to a treatment for peeling off a surface layer of the rough zinc wire; and (10) subsequent to the peeling treatment, drawing the rough zinc wire to form a fine zinc wire.
