The production process of hot-dip galvanized coil

1. Raw material preparation: Select high-quality cold-rolled steel sheet as the base material to ensure that its surface is clean and free of impurities.

2. Pickling treatment: Remove the oxide scale and rust on the surface of the steel sheet to prepare for subsequent galvanizing.

3. Cleaning: Use clean water to thoroughly rinse the pickled steel sheet to ensure that there is no residual acid on the surface.

4. Plating aid treatment: Apply a layer of plating aid on the surface of the steel sheet to improve the adhesion of the galvanized layer.

5. Hot-dip galvanizing: Immerse the treated steel sheet in molten zinc liquid to make the zinc liquid evenly adhere to the surface of the steel sheet.

6. Cooling: Rapidly cool the galvanized steel sheet to fix the galvanized layer.

7. Surface treatment: Perform surface flattening, passivation or oiling as needed.

8. Quality inspection: Test the appearance, thickness, adhesion and other indicators of the finished product.

9. Coiling: Roll the galvanized steel sheets that have passed the inspection into coils for easy transportation and subsequent processing.

This process ensures that the hot-dip galvanized coils have good corrosion resistance and surface quality, and can meet various application requirements.

Advantages of hot-dip galvanized coils

If someone asks which processing technology is one of the most common, effective and economical atmospheric corrosion resistance processes, then my answer must be the hot-dip galvanizing processing technology.

Hot-dip galvanized steel coils have ideal comprehensive properties such as corrosion resistance, forming, and coating. At the same time, it has the advantages of low cost and excellent appearance, and its application range is very wide.

Generally speaking, the service life of hot-dip galvanized steel can exceed 30 years. During use, the hot-dip galvanized layer of steel does not require maintenance, the hot-dip process is simple, and it is highly adaptable to the shape and size of steel. In addition to plate and strip steel, the hot-dip process is also widely used in steel pipes, steel wires and structural parts, and has high production efficiency. In terms of economy, compared with other protective coatings, the hot-dip galvanized layer has significant competitive advantages, especially for parts that are used for a long time, the cost of the hot-dip galvanized layer is much lower than that of the paint coating.

Uses of hot-dip galvanized steel sheets
In foreign countries, the main application areas of hot-dip galvanized steel sheets include construction, automobile and electrical appliance industries, which account for the vast majority of hot-dip galvanized steel sheet consumption. However, in China, in addition to the construction and automobile industries, light industry is also an important user. In addition, agriculture, animal husbandry, fishery and commercial fields also have a large demand for hot-dip galvanized steel sheets.
