It has been found that the carbon monoxide in gases emerging from a converter tends to burn to carbon dioxide by contact with oxygen in the surrounding air and that the flame so produced has an intensity which is closely related to the rate of flow of carbon monoxide, and hence to the rate of decarbonization of the iron. This is made use of in the invention by controlling the flow of gases emerging from the converter spout and measuring, generally continuously, the intensity of the flame produced when placed in contact with the surrounding air in a hood.
