摘要 |
Decarburization of molten steel (3), especially in stainless steel production in a metallurgical vessel (2) and particularly a converter, involves treatment with oxygen and an inert gas if required and especially argon and/or nitrogen. To decarburize molten steel with carbon content of at most 0.3 wt.%, the gas is introduced through an opening (5) below the molten steel level and a blower lance (6, 7) over the molten steel surface, to bring the gas into contact with the metal. |
