JISteel Refractory Fire Brick Inner Nozzle and Collector / Nozzle Ladle Nozzle Brick
Zirconium Tundish Nozzle
The zirconium sizing nozzle is made of stabilized zirconia and imported natural oblique zircon after being stabilized by a special process, and then formed by high-pressure molding and high-temperature firing. The nozzle model can be set according to the different steelmaking environment and use requirements of users.
Product Features:
This product has the characteristics of high refractoriness, good thermal shock performance, corrosion resistance, erosion resistance, small diameter expansion and long service life.
Applications:
This product is mainly used for continuous casting of tundish billets, blooms, rectangular billets, and small slabs for pouring steel.
