Electrical Galvanized Steels Production Process Introduction

1. Input Process: The entry point of the electrogalvanizing line is equipped with a pay-off reel, a shearing M/C, a welding M/C, a looper, and a tension leveler. The pay-off reel transports stacked or cold rolled steel materials to the shearing machine, which cuts and connects them in preparation for welding, followed by the welding process.

2. Pre-Treatment Process: An electrolytic cleaning line comprises an electrolysis tank, an acid bath, and a rinse tank to effectively remove contaminants and oxide films from the surface of the steel before electroplating, ensuring a clean and suitable surface for the subsequent processes.

3. Electrical Galvanizing: The CAROSEL method, along with other electric galvanizing techniques, involves the plating of one side at a time using a conductor roll. This process results in two-sided, single-sided, or differential-sided plated sheets. Additionally, the horizontal type allows for simultaneous plating of both sides of a sheet, producing a two-sided plated sheet.

4. Phosphate Thin-Film Coating: A phosphate thin-film is applied to the surface of the zinc layer through chemical or electrochemical reactions, providing temporary anti-corrosion protection and creating a secure painting substrate.

5. Anti-Fingerprinting Process: An organic, inorganic, or organic-inorganic hybrid film is applied to the surface of sheet steel to enhance corrosion resistance and desirable properties such as resistance to fingerprint marks and improved workability.

6. Output Process: The exit point of the line includes an output looper, tension reel, and an automatic packaging line to protect the products after coil winding, ensuring the safe and secure handling of the finished products.
