description The invention belongs to the technical field of steel production, and relates to a method for effectively judging the explosion of a tundish collector nozzle, which is characterized in that accurate judgment is made under different casting conditions by observing the combustion flame change of mold powder of a crystallizer and combining the argon flow regulation of a stopper rod and the manual inspection of the liquid level of the crystallizer. By observing the combustion flame of the mold powder of the crystallizer, the sign of nozzle bursting can be found in time, the distinguishing degree and observability of nozzle bursting are improved, and quality accidents and breakout risks caused by nozzle bursting are avoided. By integrating stopper rod argon flow adjustment and manual inspection of the liquid level of the crystallizer, the situation of nozzle bursting can be further confirmed, the accuracy and reliability of judgment of nozzle bursting are improved, and a basis is provided for treatment of nozzle b
