In a process for refining metal in a top-blown oxygen converter the composition of the exhaust gases is analyzed continuously and the gas flow volume flowing through the exhaust gas treating apparatus is adjusted so that the analysis of the gas coincides with a predetermined variation thereof with time. The above procedure enables the carbon content of the metal bath to be controlled continuously and can give an exhaust gas with a very high CO content.
