Continuous hot-dip galvanizing and aluminized zinc coating production line
The continuous hot-dip galvanizing and aluminized-zinc coating production line is a core piece of equipment in modern steel processing. It employs a continuous strip-operation method and utilizes in-line annealing technology—such as the Sendzimir or U.S. Steel process—to achieve efficient, high-quality coating production.

Continuous hot-dip galvanizing and aluminized zinc coating production line
The steel strip galvanizing (aluminum-zinc) production line continuously applies a zinc or aluminum-zinc coating onto the surface of cold-rolled steel sheets using a hot-dip method, enhancing the steel’s corrosion resistance and improving its aesthetic appearance. The main process steps include degreasing and cleaning of the steel surface, annealing and reduction treatment, hot-dip galvanizing, and post-galvanizing shape control. Our company designs production lines tailored to meet customers' diverse needs, offering both wide-strip and narrow-strip production lines.
Characteristics of the production line:
1. Employing advanced USS production technology;
2. Utilizing the waste heat from the annealing furnace can maximize energy savings.
3. Equipped with a technologically advanced ceramic-sensing zinc pot and air knife system, effectively controlling the coating thickness;
4. The process section is equipped with a finishing machine, which effectively improves the flatness of the plate surface, eliminates the yield plateau, and enhances product quality.
5. Employing a technically mature and easy-to-maintain straightening machine effectively improves the plate shape.
6. The production line is equipped with multiple CPC edge-control systems, and the winder features an EPC edge-aligning device, ensuring stable operation of the production line.
7. The electrical control system employs Siemens AC variable-frequency speed control, featuring a high degree of automation.

Aluminum alloy casting is a manufacturing process that involves pouring molten aluminum alloy into a mold, allowing it to cool and solidify into the desired part shape. It is widely used in industries such as automotive and aerospace. The main casting methods include sand casting, metal die casting, die casting, and low-pressure casting, each suited to different levels of complexity and production volumes—for instance, sand casting is ideal for large components, while die casting enables high-precision, high-volume production.
