International Journal of Instrumentation Technology (IJIT), Vol. 1, No. 1, 2011

Abstract: Detection and removal of slag from the molten metal is an important aspect of steel making process. The application of infrared imaging, spectroscopic method and other contact type slag detection methods are inappropriate as far as caster slag detection is concerned. The detection of vibration due to slag flow has a major shortcoming. In the present article, a simple imaging technique is presented for caster slag detection. The imaging technique is based on the detection of sudden increase in the light intensity by a CCD camera as the slag floats immediately as it enters the tundish through the shroud in a casting operation. The camera is connected to a computer. As the detected light exceeds the predetermined limit, the system generates the indication of the onset of slag.
