Title:
METHOD FOR DETECTING SLAG IN MOLTEN STEEL FLOW
Document Type and Number:
WIPO Patent Application WO/2018/151075
Kind Code:
A1
Abstract:
This method for detecting slag in a molten steel flow includes: an imaging step for capturing a plurality of images by sequentially imaging a molten steel flow which includes molten steel and slag and flows from a steel converter toward a ladle; a histogram creation step for creating a histogram for each captured image; a maximum peak detection step for detecting a maximum peak, which is the maximum pixel number value in each histogram; and a maximum peak type determination step for determining whether or not the maximum peak in each histogram corresponds to the slag or the molten steel.
