Zusammenfassung:	To provide a dross detection system and a dross detection method that detect dross floating on a surface of molten metal more accurately, according to the present invention.SOLUTION: A dross detection system according to the present invention is a dross detection system 1 which detects dross floating on a surface of molten metal, and comprises: an infrared detection device 2 which detects infrared rays emitted from the surface of the molten metal; a measurement part 31a which is configured to control the infrared detection device 2 to measures infrared-ray intensity of the infrared rays emitted from the surface of the molten metal; and a detection part 31b which is configured to detect the dross on the basis of temporal variation in the measured infrared-ray intensity due to waving of the surface of the molten metal.SELECTED DRAWING: Figure 3 【課題】本発明は、溶融金属の表面に浮遊するドロスをより正確に検知するドロス検知システムおよびドロス検知方法を提供することを目的とする。【解決手段】本発明のドロス検知システムは、溶融金属の表面に浮遊するドロスを検知するドロス検知システム１であって、溶融金属の表面から放射される赤外線を検出する赤外線検出装置２と、赤外線検出装置２を制御して、溶融金属の表面から放射される赤外線の赤外線強度を所定期間に亘って測定するように構成される測定部３１ａと、測定された赤外線強度の、溶融金属の表面の波立ちに起因した時間変化に基づいて、ドロスを検知するように構成される検知部３１ｂとを備えることを特徴とする。【選択図】図３
