1.9–2.55mm Electric Galvanizing Wire Production Line / Galvanized Steel Wire Production Line

Galvanization is a common surface treatment technology primarily aimed at preventing rust. After being treated by the galvanizing process, the steel wire takes on a bright silver appearance, offering high toughness and corrosion resistance, and its service life is greatly extended, making it resistant to oxidation and deformation in open-air environments. Galvanized steel wire is strong, durable, and extremely versatile; it can be used to make springs, nails, coat hangers, wire ropes, as well as for weaving fences, wire mesh, floral tying materials, and more, holding high application value in industrial mining, building protection, agricultural planting, and other fields.

Galvanized wire is divided into hot-dip galvanized wire and cold galvanized wire (electric galvanized wire). The hot-dip process involves applying a fluxing agent to the surface of the steel wire, then immersing the wire into molten zinc solution; after cooling, an alloy coating forms on the wire surface. Hot-dip galvanized wire has a thicker zinc layer, offering stronger corrosion resistance, with a maximum zinc content of up to 350 g/m². The cold galvanizing process uses electrolytic equipment, applying positive and negative electrodes to the steel sheet and the plating solution respectively, causing zinc atoms to deposit onto the steel surface and form an alloy coating. Electric galvanized wire has a thinner zinc layer, typically only 10 to 50 g/m². However, the strength and performance of electric galvanized wire are not affected by heat treatment, and the process is relatively simpler with lower production costs. Both hot-dip galvanizing and electric galvanizing have their respective advantages.

Introduction to the Electric Galvanizing Production Line Equipment

1.Passive Coil Pay-off Equipment

Due to regional differences and varying production requirements, the specifications of passive coil pay-off equipment needed by different regions and factories are not uniform. You can either purchase this equipment yourself or have it customized by us according to your specific needs.

2. Steel Wire Heat Treatment Furnace (one set)

The steel wire heat treatment furnace modifies the internal structure of the wire by precisely controlling the heating and cooling processes, thereby enhancing its toughness, strength, and corrosion resistance. The furnace is equipped with high-efficiency heating elements and a temperature control system, ensuring that every wire undergoes heat treatment in a uniform temperature environment.

3.Temperature-controlled Water Washing Tank

4.Environmentally Friendly Turbulent Fume-free Pickling Tank

The pickling tank efficiently removes scale, rust, and impurities from the steel wire surface through an electrochemical reaction, ensuring a clean and highly active substrate surface in preparation for the subsequent galvanizing process. Pre-pickling the wire significantly improves zinc layer adhesion and overall coating quality. The environmentally friendly turbulent fume-free pickling tank produced by our factory features a closed design that minimizes the escape of harmful gases, ensuring an environmentally safe production process.

5.Three-stage Cold Water Washing Tank

The water washing tank is responsible for repeatedly cleaning the iron wire during the electroplating process, effectively removing residual acidic and alkaline solutions, electrolytes, and other impurities from the surface. This prevents contamination of the solutions in subsequent treatment tanks and ensures coating adhesion and surface quality. It is a critical step in guaranteeing the uniformity and corrosion resistance of the galvanized layer.

6.Four-stage Electroplating Tank

The electroplating tank acts as a container for the electrochemical reaction. Under the action of direct current, zinc ions are uniformly deposited onto the steel wire surface, forming a corrosion-resistant, aesthetically pleasing, and functional zinc coating. It is the most critical process unit in the galvanizing production line.
