Sizing nozzle

The main component of the nozzle is zirconia, which has the characteristics of high fire resistance, good thermal shock resistance, erosion resistance, erosion resistance, small diameter expansion and long life. With the help of the quick-change system, multiple down nozzles can be replaced in one pouring of the tundish to match the long-life tundish lining.
