Zinc galvanizing

Zinc galvanizing means and types of manufacturing

The main step in the zinc galvanizing process and its types of treatment is the artifacts’ immersion in molten zinc at approximately 450° C.

Among the many procedures, those that stand out for their efficiency and affordability are: discontinuous hot dip zinc galvanizing (known as “batch”), sheet metal galvanization (the Senzimir method) and cold galvanizing (done through electrolysis). A procedure gets chosen depending on the product’s measures, expected service lifespan, and preparation types. In the first category, introducing the items suspended with crossbeams into a zinc bath makes for the actual galvanizing stage.

During the descent into the hot dip zinc tank, the ferrous surface is released from the fluxing salts: the parts that get liberated from the oxide coating are then soaked, allowing for the metallurgical reaction to take place. Steel reacts with zinc, creating a protective coating. Ore bathing times vary between 5 and 20 minutes.

Vats are built from an alloy that’s low-reacting to zinc content in the fusion. There are two types of furnaces: those with a burner in the induction combustion chamber, immersed electric candles or heated from above. The most common ones are those with flat flame or high speed burners.
