Abstract
In a Bessemer process for the purification of iron, steel non-ferrous metals and ferroalloys, the metal bath is first blown with a blast of oxygen-enriched air until the major portion of the oxidizable impurities has been removed and then with a blast of air enriched with nitrogen or its equivalent until the removal of the impurities to the desired extent has been completed. The surplus nitrogen separated from the air used to produce the oxygen for enriching the blast may be used for diluting the blast for the second part of the blow. Instead of nitrogen, one or more gases in Group O of the periodic table may be used.
