The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical reaction between iron from the steel surface and the molten zinc, resulting in the formation of Zn/Fe alloy layers bonding the coating to the steel surface. Horizontal Hot-Dip Galvanized Line The hot-dip galvanization process is one of the most commonly used and applicable anti-corrosive treatments to steel strip products. There are two types of the annealing methods: (1) the off-line annealing; and (2) the on-line annealing manufacturing process methods. Galvanizing Conference, Australia, September 8, 1996. 2.0 Introduction Use of the nickel-zinc (NiZn) galvanizing process has proven to be the most practical and effective method of dealing with the problems associated with the hot dip galvanizing of silicon-containing steels. These steels, which are commonly referred to as Hot dip galvanizing process is known as one of the tech-niques frequently used for protecting low carbon steels against corrosion. This procedure consists in applying a galvanized coating on steel surface by immersion in a molten Zn bath at about 450°C.
