Abstract:
A process and a device for melting aluminum where solid aluminum is melted in a furnace to form aluminum melt pool. The temperature and carbon monoxide (CO) concentration of the flue gas generated in the melting process is detected and examined for variations. Using this variation information, it is determined if aluminum oxides have formed on the surface of the aluminum melt pool and if they have, the melting process is regulated accordingly.
