Continuous Galvanizing Line
Comprehensive Solutions for the Wire Industry
At FCPHOTON we design and manufacture high-speed continuous galvanizing lines for the production of galvanized wire, developed as a faster, more efficient and environmentally friendly alternative to traditional galvanizing lines.
This continuous galvanizing line replaces some common elements of the conventional process. The result is an industrial solution capable of operating at higher speeds, reducing the environmental impact of the process, and maintaining the quality of the final wire coating.
What is a Continuous Galvanizing Line?
A continuous galvanizing line is an industrial facility designed to coat wire continuously, without interruptions between the different phases of the process.
In this type of line, the wire advances continuously through the stages of winding, pickling, drying, heat treatment, stabilization, cooling, coating, draining, final cooling and coiling.
Differences compared to a Traditional Galvanizing Line
Lower Environmental Impact
It reduces dependence on fossil fuels and uses a more controlled chemical process.
Electrical Induction
Ovens powered by natural gas or LPG are being replaced by faster and more efficient electric induction ovens.
More Eco-Friendly Pickling
Hydrochloric acid is replaced by ultrasonically activated phosphoric acid, which helps to clean the wire effectively.
Higher Speed
The line can be two to three times faster than a traditional galvanizing line, depending on the project characteristics.
Optimized Process
In the traditional line, heat treatment is performed before pickling. In the continuous galvanizing line, the process begins with pickling, followed by induction heat treatment.
High speed and production efficiency
One of the main advantages of this continuous galvanizing line is its ability to operate at high speed. The electric induction systems allow annealing temperatures of between 780°C and 800°C to be reached very quickly, with optimized energy consumption and a very rapid thermal response.
Because the heating process is so rapid, it includes a subsequent stabilization phase. During this stage, the wire remains in the process for the necessary time to regain its mechanical properties, such as ductility and tensile strength.
In this way, the line combines speed, energy efficiency and final quality of the galvanized wire.
Frequently Asked Questions about the Continuous Galvanizing Line
What advantages does a continuous galvanizing line have over a traditional one?
The continuous galvanizing line allows for faster operation, reduced use of fossil fuels, and process optimization through technologies such as electrical induction, phosphoric acid, and ultrasound.
What type of wire can be processed on a continuous galvanizing line?
It can be designed to work with different wire diameters and formats, adapting the winding, heat treatment, coating, draining and coiling systems to each project.
Does the continuous galvanizing line allow for the production of more wire?
Yes. This line can be two to three times faster than a traditional line, depending on the configuration, wire diameter, and production needs.
What is the difference between zinc coating and Galfan?
The zinc coating protects the wire from corrosion. Galfan, composed of zinc and aluminum, can offer superior protection in certain industrial applications.
What is the function of the inert atmosphere in the process?
The inert atmosphere protects the wire surface before coating, preventing contamination and promoting proper adhesion of zinc or Galfan.
What is forming gas?
Forming gas is a mixture of nitrogen and hydrogen used to create a controlled atmosphere during the process. Its function is to protect the wire before the coating phase.
Can the continuous galvanizing line be adapted to the available space in the plant?
Yes, we design custom continuous galvanizing lines, taking into account the available space, production capacity, wire type and the technical requirements of each facility.
