ThyssenKrupp Installs Two New AODs
In the stainless steel industry, carbon-rich primary heats produced in an electric-arc furnace (EAF) are further processed in special converters such as the AOD. The molten metal from the EAF is poured into the converter, and oxygen or a mixture of oxygen and other gases such as nitrogen or argon are added. The undesirable carbon in the steel burns off in the converter and passes into the flue gas, while chromium remains in the molten metal. The carbon-rich flue gas is extracted and filtered.
