How is zinc added to the galvanizing kettle?
Zinc is added to the kettle in three primary ways, depending on the amount of zinc being added to the kettle. When a large amount of zinc is added to the kettle it is usually in the form of ingots, which are commonly known as zinc pigs. Zinc pigs are simply chained to a crane and then slowly lowered into the galvanizing kettle until they melt. When smaller amounts of zinc are added to the kettle, such as in 25 kg blocks or zinc pellets, they can simply be placed directly into the zinc in the kettle. It is important to take the appropriate safety precautions when adding zinc into the galvanizing kettle as splashing of the molten zinc can occur.
