Beschreibung
Zusammenfassung:	In a method and a device for controlling a carbon monoxide output of an electric arc oven, comprising an oven container, an arrangement for determining a height of a foamed slag in at least three zones of the oven container on the basis of a solid-borne sound measurement, at least one first device for controlling an oxygen infeed, and at least one second device for controlling a carbon infeed into the oven container, the height of the foamed slag is determined in each of the at least three zones and associated with a carbon monoxide content in the exhaust gas of the electric arc oven, wherein the carbon infeed and/or the oxygen infeed in at least one of the at least three zones is controlled such that the height of the foamed slag is maintained below a maximum value.
