Ladle slag detection technology for the continuous casting of steel is of great practical significance, which can effectively improve the quality of slab, increase the yield of molten steel and prolong the service life of tundish. Review slag detection technology at home and abroad and its application , Pointed out the main problems existed in practical application.The key points of the detection principle and the signal processing flow of vibrating ladle slag detection method are described emphatically.Aiming at the low recognition stability of the vibration ladle slag detection technology , And the long time of debugging, the key technologies such as the construction of water modeling experimental platform, swirling roll scupper mechanism of two-phase flow confluence, the forced vibration response of the spout casing and the optimization of the steel flow shock and vibration signal are analyzed in depth , And gives the corresponding research ideas and suggestions.
