Processing technology of hot dip galvanizing equipment

Hot dip galvanizing is a special method of immersing steel components in molten zinc to obtain a metal coating. And with the support of some high-voltage transmission and communication businesses in the past few years, it has greatly stimulated the demand for hot-dip galvanizing equipment. Today, Xiaobian will briefly talk about the process of hot dip galvanizing equipment t.

First, the formation process of hot-dip galvanized layer In practical workpiece applications, it is often necessary to thermally immerse the surface to form an iron-zinc alloy. As long as the good combination between the iron and the pure zinc layer is ensured, the interdiffusion of the two elements of zinc and iron can be achieved. The migration is achieved in a certain collective lattice, so that the attraction between the atoms is relatively small. It is convenient to form a hot-dip galvanized layer which is relatively stable in structure. This is also one of the ultimate goals of hot dip galvanizing equipment.

Second, the process of hot-dip galvanizing layer

The general process mainly includes workpiece, degreasing, water washing and pickling. At the same time, the next step of the impregnation plating solvent is carried out, and the drying and preheating are carried out under limited conditions. During the period, it is necessary to properly control the temperature of the zinc bath, the time of the immersion, and the speed at which the workpiece is extracted from the zinc liquid. Try to avoid a large amount of pollution problems in the hot dip galvanizing equipment, and use chromium-free during passivation. Passivation. Throughout the process, attention should be paid to the overall operation of hot dip galvanizing equipment.

All in all, in order to meet the production requirements and inspection standards of the factory, it is necessary to understand the basic principles and application knowledge of hot dip galvanizing equipment, and to control the appropriate coating thickness and temperature on a certain basis. Enhance the protection requirements for steel parts, and further meet the demand for hot-dip galvanizing.
