The tundish usually adjusts the joint between stopper rod and tundish nozzle to control the flow of molten steel from tundish to crystallizer. In the entire casting process, by abnormal erosion on the contact surface of stopper rod and tundish nozzle, the proper speed cannot be guaranteed. The ZrO2 insert has an important impact on the service life of tundish.
The main component of Soar tundish nozzle with ZrO2 Insert is made of zirconium, which has the characteristics of high refractoriness, excellent thermal shock stability, erosion and corrosion resistance.
