How to use galvanizing furnace should be maintained

Iron and steel materials are easily corroded by oxidation in the atmosphere, affecting their service life. Zinc plating on steel can delay its surface corrosion and prolong its life. Hot galvanized products can be used in various fields. To obtain such products, the hot galvanized process must be performed. The acid washed steel is immersed in the molten zinc liquid of the galvanizing furnace to form a zinc alloy coating to protect the steel from corrosion.

Boiler equipment must be in hot galvanizing treatment, this is to heat, so that the temperature of zinc can reach 400 degrees above, can reach the melting state, but also good chemical reaction with steel. Boilers have traditional coal-fired and modern natural gas types, of which coal-fired boilers are more commonly used. How do you heat the molten zinc with a boiler? The proper furnace temperature must be guaranteed. Whether it is too high or too low, it is not conducive to the heating of the boiler and will cause the quality of hot galvanized products to be unstable. The temperature of the galvanizing furnace is better controlled, and the quality of galvanizing products can be obtained according to the correct operation method to ensure that the galvanizing process is normal.

Use boiler equipment and good protection, how to do it? The first is to regulate the use of operations, do not cause the boiler internal leakage due to the wrong operation. The next is the cleaning of the boiler, to use good quality water cleaning, to prevent the internal galvanizing layer fall off. When cleaning, also pay attention to the strength of the control, not too strong, and not too small to clean up some of the residue did not clear. Finally, regular inspection, boiler equipment or regular special inspection, there are found problems can be handled in a timely manner, will not affect production operations. Pay attention to these aspects, can be the correct use of galvanizing furnace and good maintenance.
