Vacuum Degassing of Steel - Vacaero
During steel manufacturing, the molten steel is poured from the melting furnace into a vessel referred to as a teeming ladle (Fig. 2). In the ladle (aka tank) degassing method, the ladle is placed into a vacuum chamber, the chamber is sealed and a vacuum of 0.7 - 13.0 mbar (0.5 mm - 10.0 mm Hg) is applied.

An Overview of Steelmaking Process, Global Market ... - Steel Technology
Refining: Steelmaking. To make steel, refining of iron needs to be carried out. In this process, the carbon content of hot metal is lowered, usually to less than 1% by an oxidation process in a steelmaking furnace. At the same time, alloying materials are added to the furnace to attain the required chemical composition of the final product.
