Why is Zinc Susceptible to Storage Stain (White Rust)?zinc is very reactive metal. It exhibits a low corrosion rate only because a continuous passive film forms on the surface of the zinc coating. A key part of the corrosion reaction is that the surface needs to dry in the presence of air in order to develop and maintain the passive film. It is during the drying part of a rain cycle that the zinc...

Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers.
