Method for manufacturing brass-plated steel wire and brass-plated steel wire

摘要

Provided is a method for manufacturing a brass-plated steel wire in which improvement in the quality of the brass-plated steel wire and energy saving in the manufacturing process are balanced and a brass-plated steel wire obtained by the method.;The method is a method for manufacturing a brass-plated steel wire comprising a plating process in which a steel wire rod is brass plated and a final wire drawing process in which the obtained brass-plated steel wire rod is subjected to a final drawing. The method includes a zinc oxide removing process in which the amount of zinc oxide on the surface of the brass-plated steel wire rod is made smaller than 50 mg/m2 before the final wire drawing process.

1. A method for manufacturing a brass-plated steel wire, comprising:
brass-plating a steel wire rod; removing zinc oxide from the surface of the brass-plated steel wire rod by a pickling treatment, wherein the amount of zinc oxide remaining after the removing of the zinc oxide is smaller than 50 mg/m2; and final drawing the obtained brass-plated steel wire rod after the removing of the zinc oxide; wherein a cleaning liquid used for the pickling treatment is a phosphoric acid solution; and wherein the concentration of the phosphoric acid solution and acid treatment time satisfy the relationship represented by the following expression: 72 (g/L·s)≧phosphate concentration (g/L)×treatment time (s)>5.0 (g/L·s).
