- Hot-Dip Galvanizing: A proven method that provides a thick, protective zinc coating for long-term corrosion resistance.
At HIT Steel Fabrication and Galvanizing, our steel galvanizing process is designed to provide exceptional corrosion protection and durability for a wide range of applications. Our comprehensive galvanizing solutions involve several key steps, each meticulously executed to ensure the highest quality and performance of our galvanized steel products.
Flux Treatment
The galvanizing process begins with flux treatment, where steel components are immersed in a flux solution to remove any surface oxides and impurities. This step is crucial for ensuring a clean surface that promotes strong adhesion of the zinc coating. Our advanced flux treatment process ensures thorough preparation, which enhances the effectiveness of galvanizing.
s an essential step in the galvanizing process, serving to prepare the steel surface for the application of the zinc coating. By removing impurities, oxides, and other contaminants from the steel surface, flux treatment ensures that the zinc coating adheres properly and provides optimal corrosion protection.
Types of Flux
There are several types of fluxes used in the galvanizing process, each with its own specific properties and applications:
Molten Zinc Chloride
Zinc Ammonium Chloride
Organic Fluxes
Flux Application Methods
The flux can be applied to the steel surface using various methods, including:
Dipping
High Velocity Furnace
A high-velocity furnace is a specialized piece of equipment used in the galvanizing process to heat the steel components to a temperature suitable for zinc coating. It plays a crucial role in ensuring the quality and uniformity of the galvanized finish.
High-velocity furnaces are designed to reach and maintain high temperatures (500-550°C) required for zinc melting and application. Equipped with powerful burners or heating elements, these furnaces rapidly heat steel components, ensuring even heat distribution and preventing variations in coating thickness and quality. We operate our high-velocity furnaces under a controlled atmosphere (e.g., nitrogen or argon) to safeguard the steel surface from oxidation during the heating process.
Dryer
After the zinc coating is applied, the galvanized steel components are transferred to a dryer. The drying process removes excess moisture and ensures that the zinc coating cures properly, achieving the desired hardness and durability. Our dryers are designed for optimal performance, ensuring consistent and reliable results.
Acid Neutralization
The final step in our galvanizing process is acid neutralization. This involves treating the steel components to neutralize any residual acid from the flux treatment, preventing potential damage to the coating and ensuring a clean and stable finish. Our acid neutralization process ensures that the final product meets our high standards for quality and performance.
