The stopper rod supporting tundish zirconium nozzle is inlaid in the seat brick at the bottom of the tundish, and cooperates with the stopper rod to control the flow of molten steel. The nozzle of LMM series tundish has the characteristics of good erosion resistance, good thermal shock stability, anti-erosion and anti-clogging. With the integral plug rod produced by our company, it can significantly increase the number of tundish continuous casting furnaces.
