Galvanizing tank for steel wire

Abstract

The invention relates to a steel wire electrogalvanizing trough, which comprises a lower liquid storage tank and an upper electroplating work tank. The lower liquid storage tank is communicated with the upper electroplating work tank through a drain pipeline and a circulating pump. The upper electroplating work tank is internally provided with at least two cathode pools, and an anode pool is arranged between every two cathode pools, each cathode pool is internally equipped with a cathode device, each anode pool is internally equipped with a set of anode device, the anode device consists of anode copper plates and zinc plates, the at least two anode copper plates are both arranged along the width direction of the upper electroplating work tank, and both ends of the anode copper plates are fixed on the front and back side walls of the upper electroplating work tank. Several zinc plates are disposed between adjacent anode copper plates, the planes of the zinc plates are parallel to the length direction of the upper electroplating work tank, and both ends of the zinc plates are connected to the adjacent anode copper plates. The zinc plates adopted by the invention are used both as an anode conductor and a zinc source, and lead, titanium or nickel plates are not needed any more to serve as an anode conductor, thus being conducive to improving the steel wire electrogalvanizing quality.

Description

technical field [0001] The invention relates to equipment for electrogalvanizing steel wires, in particular to a steel wire electrogalvanizing tank using zinc plates as a zinc source and simultaneously as an anode conductor, belonging to the technical field of metal processing equipment. Background technique [0002] With the continuous development of the industrial level, more and more various types of steel wires are used in various occasions. Especially galvanized steel wire, its surface is smooth, bright and clean, without cracks, thorns, scars and rust, and the galvanized layer has the advantages of uniform distribution, strong adhesion, durable corrosion resistance, excellent toughness and elasticity, and has been widely used in China. All walks of life have been widely used. [0003] Electrogalvanizing, also known as cold galvanizing, is the process of forming a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of the plated part by elect...

AI Technical Summary

Problems solved by technology

In the existing steel wire electrogalvanizing equipment, a cathode gun and an anode conductor are arranged in the steel wire electrogalvanizing tank, wherein the anode conductor is a metal row, usually made of lead, titanium or nickel, so that in the production process, the steel wire electroplating There will inevitably be lead, titanium or nickel molecules in the zinc sulfate liquid in the zinc bath, and these metal molecules will adhere to the surface of the product, affecting the smoothness, aesthetics and quality of the product
