1. BZ type AL-C based material having good erosion resistance and good thermal resitance properties.

2.BZ type AL-C based material for the bowl structure part having high corrosion resistance.

3. BZ-type anti-blocking material can prevent Al2O3 adhesion inside of the tundish nozzle which helps prevent nozzle be blocked.

4. BZ-type argon blowing design can help prevent Oxygen inhalation.

5.High wearing resistance and actuate dimension used in the bottom materials ensure the nozzle to achieve quick change.
