A method for recovering unburnt exhaust gases in an oxygen converter, characterized by the control of an exhaust gas damper by a control signal obtained by signal-processing, in accordance with the set functional formulae, an exhaust gas damper control signal obtained from a pressure differential between throat pressure and atmospheric pressure, and an exhaust gas damper prediction control signal obtained by continuously detecting the quantity of oxygen fed, the quantity of secondary raw material charged, the composition of exhaust gases and the flow rate of exhaust gases to calculate the quantity of furnace generated gases and the quantity of combustion exhaust gases at throat.
