Continuous casting machine tundish slag entrapment forecasting method based on tapping detection

The invention provides a continuous casting machine tundish slag entrapment forecasting method based on tapping detection. The method comprises the steps of firstly, installing a tapping detection coil; secondly, after continuous casting machine tundish starts pouring, acquiring the tundish molten steel weight T[tundish], a tapping detection tundish slag entrapment rate P[slag entrapment], a corresponding casting flow pouring length value L[casting flow], and a corresponding flow casting speed Vc; thirdly, when the tundish molten steel tonnage weight W [tundish] is larger than the tundish final pouring tonnage standard maximum value Wmax, and a casting blank is cut off, determining the abnormity level of the tundish slag entrapment rate, and a handling manner; fourthly, when the tundish molten steel tonnage weight W[tundish] is smaller than the tundish final pouring tonnage standard maximum value Wmax, determining the abnormity level of the tundish slag entrapment rate, and a handlingmanner, and when the actu
