ELECTROLYTIC GALVANIZING LINE FOR STEEL WIRE
Galvanized wire is widely used in industry and in everyday needs. It has good flexibility and durability, is not subject to corrosion, is used in the construction of fences, fixing various structures, some parts of mechanisms also can not do without it. The zinc layer extends the service life of the product at least three times, as it is not affected by atmospheric moisture that causes rust.
Galvanic galvanizing is an electrolytic method of applying a thin protective layer of zinc to the product, the surface of which must be prepared in advance. This method allows obtaining coatings with thickness of 5-40 microns. The electrolytic method of galvanizing wire is now widely used. The main advantage of this method is the possibility of obtaining highly plastic and uniform zinc coatings.
Electrolytic method of zinc application in comparison with other zinc-coating methods is distinguished by high productivity of the zinc-coating process, low cost price, rather high level of protection of products afterwards, uniformity of zinc coating without leaks, drops, with preservation of shape and dimensions of the product. It is also possible to apply zinc to all areas of products with any complex shape, including various pores and obtain smooth, shiny, not requiring additional processing of decorative protective coatings.
The main advantages of the electrolytic galvanizing method are:
- the ability to precisely regulate the amount of zinc applied to the surface and to obtain a fairly uniform coating on products of simple configuration;
- high purity of electrolytically deposited zinc, depending mainly on the purity of the anodes and the chemicals used for bath preparation;
- high chemical resistance of zinc coatings produced by electrolysis due to the purity of the sludge;
- low zinc consumption due to the ability to precisely regulate the amount of zinc deposited and the thickness of the coating;
- good mechanical properties of the coating (coating elasticity and good adhesion to the substrate);
- metal savings in the electrolytic method compared to the hot method is 50 % or more;
- electrolytic zinc coatings are also quite resistant to corrosion in tropical climates.

Process Steps for Electrolytic Galvanizing Process
The technology of electrolytic galvanizing consists in deposition of positively charged zinc ions from aqueous solutions of its compounds (electrolytes) on the cathode (the product which is covered) at constant electric current flow through the solution. Zinc plates are used as an anode, placed on a bath in such a way as to ensure uniform flow of anions to the coated surface.
The sequence of the electrolytic galvanizing process: wire feeding (coiled on the disc/coil) heat treatment (annealing) water cooling etching in hydrochloric acid solution to remove rust and scale rinsing washing in water to remove solution galvanizing rinsing with hot water drying on a fast air flow steel wire rewinding to the coil.
