Small iron wire is very useful in our life, basically a lot of things will use iron wire, and iron wire can also be made into a lot of crafts, making ordinary iron wire become more aesthetic and artistic sense. Of course, the iron wire in the process of use, there will be rust, so galvanized black iron wire in the storage process, it is necessary to master the correct method.

Hot wire plating adopts zinc-free slag to add hot molten zinc and galvanizing, which avoids the traditional heating process, radiates 1653 hot molten zinc on surface 4102 of zinc liquid surface, and reduces the high temperature oxidation of zinc liquid surface. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, and the heat radiation on the zinc liquid surface is reduced.
