| 摘要 |
The invention relates to a method for metallurgical treatment of a carbonaceous metal melt during a manufacturing process, in particular during a metallurgical final treatment process or final treatment step, by means of a process gas incorporated, in particular blown, onto and/or into the metal melt, wherein a method for metallurgical treatment of a carbonaceous metal melt is improved. Said improvement is achieved in that carbon dioxide (CO2) is blown onto and/or into the metal melt, as a process gas, and is at least partially converted to carbon monoxide (CO) as a product gas in the process of the endothermic Boudouard reaction with the carbon present in, in particular released in, the metal melt. |
