New Generation Steel Strip Continuous Annealing

Hot Dip Galvanizing (Aluminizing) Technology --- JJRS-Sendzimir

The Hot-Dip Galvanizing
The freshly cleaned steel is submerged into a kettle of molten zinc at 830°-850° F. The zinc then bonds with the steel in a diffusion reaction, creating a brand-new layer of metallurgically bonded zinc alloy. Before the newly coated steel can be removed from the tank, the surface of the molten zinc must be swept to remove any residue to ensure that the steel is exiting through pure zinc.
As soon as it’s removed from the galvanizing kettle, the steel is quenched in aqueous sodium dichromate at ambient temperature to help cool it down before the final cleaning process. This also helps the galvanized steel retain its shiny surface for a longer period of time.
Once galvanized, the coated surface of the steel is cleaned of any dirt, drip marks or excess zinc to ensure the final product is ready for testing.
