Product description
As a key functional refractory material for billet continuous casting, the zirconium sizing nozzle plays the role of controlling the uniform and stable flow of molten steel from the tundish to the mold, stabilizing the casting speed, and maintaining the height of the liquid level in the mold, thereby ensuring the quality of the steel billet. To improve the efficiency of continuous casting, zirconium sizing nozzle quality directly affects the length of continuous casting time.
Advantages:
Good erosion resistance and corrosion resistance, good thermal shock stability, no bursting during use, long service life, and the use time can reach more than 20 hours.
