Clean Steel with Thermographic Slag Detection TSD 2.0

The ever-increasing demands on the degree of steel purity require the slag-free transfer of liquid steel from the oxygen steel converter or electric furnace into the ladle. A prerequisite for this demand is that entrainment of slag into the liquid steel can be detected. AMEPA’s latest slag detection system now detects slag flow into the steel on a thermographic basis.

Thermographic slag detection takes advantage of the fact that the thermal radiation characteristics of steel and slag in the higher infrared range are significantly different at the same temperature.

A thermographic slag detection system essentially comprises one infrared camera, which observes the tapping stream, an evaluation computer, and a display device. The infrared camera is installed in an air-cooled housing to protect it against damage and radiation.

The camera image is displayed in a false-color representation on a monitor at the system and on additional monitors at the tapping stand.
