Therefore, in order to protect the service life of steel or its parts, electro galvanizing is generally used to process steel.Galvanized coil: immerse the steel sheet into the molten zinc bath to make its surface adhere to a layer of zinc steel sheet. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but after it is out of the groove, it is immediately heated to about 500 ℃ to form an alloy coating of zinc and iron. This kind of galvanized coil has good coating adhesion and weldability.
Advantages of galvanized coil: it has strong corrosion resistance. It can prevent the surface of steel plate from corrosion and prolong its service life. Moreover, the galvanized roll looks very clean, more beautiful and more decorative
Advantages: the surface has strong oxidation resistance, which can strengthen the corrosion resistance and penetration ability of parts.
Galvanized coil is mainly used in air conditioning, refrigerator and other industries.
For example, the back plate of the indoor unit of the air conditioner, the back plate of the cabinet unit, the internal parts, and the shell and interior of the outdoor unit are all made of galvanized steel. The working environment of these parts will encounter strong oxidation conditions such as rain, sunlight and warm gas corrosion, so galvanized coils are often used. It plays a key role in factory and family life.
