Abstract：SERAFIN sensor for “Distance-to-scrap” determination at burner tip in electric arc furnace is developed. The process benefit of this sensor, devoted to the monitoring of the melting scraps, will be discussed. Meanwhile, its principle of measurement and the design feature of optical head are described in detail. SERAFIN sensor is an on-line “distance-to-scrap” measurement technique which is fitted inside annular burners, combined burners or oxygen lances. Industrial experiment shows that this sensor could be used to monitor the melting of scrap in front of each injector, and thus optimising its operation and detecting blow-back occurrences before any damage is created. The comparison made with the panel overheating proves their ability to predict blow-back proclivity.
