Hot dip galvanizing processing galvanizing also called hot dip galvanized and hot dip galvanizing: is an effective way of metal corrosion, mainly used for the metal structures and facilities. Will rust of steel parts are immersed into around 500 DEG C melting liquid zinc, steel pieces attached to the surface of the zinc layer, so as to prevent corrosion. Hot dip galvanizing process: refined pickling and washing - plus help bath - drying - hanging plating - cooling - drug - Cleaning - Polish - hot dip galvanized completed 1, hot dip galvanizing is by older hot plating methods, since 1836 French to hot dip galvanizing applications in industry since, there have been 140 years of history. However, hot dip galvanizing industry has been developed rapidly in recent thirty years with the rapid development of cold rolled strip.First heat treatment, and then zinc. Because if the first galvanized steel heat treatment, galvanized layer in the heat treatment will be burned, heat treatment temperature in general more than two Baidu.
