1. BZ type AL-C based material having good erosion resistance and good thermal resistance 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 the nozzle from being blocked.

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

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