The galvanising pot is the core specialised equipment in the hot-dip galvanising process, primarily used to contain molten zinc baths. It enables metal workpieces to be immersed in the zinc bath, forming a uniform zinc coating on their surfaces to achieve corrosion protection. It is widely employed in the metal surface treatment industry. Typically designed as trough-shaped vessels, they are generally equipped with heating systems (internal or external), temperature control devices, and zinc liquid agitation/slag removal components. Some large-scale pots incorporate zinc liquid circulation and insulation structures to maintain stable temperature and uniform composition. The galvanising pot melts solid zinc ingots into liquid zinc at temperatures between 440°C and 460°C via its heating apparatus. Steel components undergo pretreatment—including degreasing, rust removal, and fluxing—before immersion into the molten zinc. A metallurgical reaction occurs between the iron and zinc on the component's surface, forming a dense zinc - iron alloy layer and a pure zinc layer. Upon cooling, a corrosion-resistant galvanised coating is obtained.
