Principle and production process of hot dip galvanizing

Hot dip galvanizing is also known as hot dip galvanizing. It can also be called hot dip galvanizing or hot dip galvanizing. This method plays a big role in anticorrosion and can be used on metal structure equipment of various industries. The reason why it can prevent corrosion is to use the principle of melting zinc liquid to play the role of anti-corrosion. Let's take a look at the specific principles and production processes.

Principle of hot dip galvanizing

In fact, the iron piece that cleans the feeling is subjected to the wetting action of Flux, and it is put into a zinc bath to chemically react to produce a film. Excellent hot dip galvanizing should be carried out under the control of each process to fully exert the good working effect of this process. Temperature and speed also need to be noted, it plays a big role in the entire process. Especially the thickness, so in general, the speed is about 1.5 meters a minute.

Hot dip galvanizing production process

The first is the original board preparation, followed by pre-plating treatment, hot dip plating, post-plating treatment and finished product inspection. We often divide the hot dip galvanizing process into off-line annealing and in-line annealing according to the different treatment methods. The out-of-line annealing is annealed before the hot-rolled steel sheet or the cold-rolled steel sheet enters the hot-dip galvanizing line, and the in-line annealing is directly provided. Cooling is also an indispensable part. Generally speaking, water is cooled and the temperature is suitable. It can neither be higher than 70 degrees Celsius nor less than 30 degrees Celsius.

The principle and production process of hot dip galvanizing is probably the same. Nowadays, with the development of society, there is an increasing demand for the protection of steel parts. Therefore, the demand for hot dip galvanizing has also increased significantly. Very good anti-corrosion effect.
