During the steelmaking process, while the molten steel is still in the ladle and before it is poured, the steel must be degassed in order to: (1) reduce/eliminate dissolved gases, especially hydrogen and nitrogen; (2) reduce dissolved carbon (to improve ductility); and (3) to promote preferential oxidation of dissolved carbon (over chromium) when refining stainless steel grades. In the steel
