Performance Characteristics 

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

2. JQ-type spinel material for bowl part ensures the parts which SEN worked with stoppers can resist the most severe erosion.

3.BZ type argon blowing design helps to prevent oxidation adhesion

4. GBZ-type Zirconium material ensures excellent corrosion resistance of slag line and is more 

5.resistant to the corrosion of fluorine-containing protective slag.

6. Inner layer with carbon free material guarantees the special requirements of ultra-low carbon steel, silicon steel and clean steel。

Function of Submerged Entry Nozzle

1. The bowl part of SEN worked with a stopper head can guarantees a perfect steel pouring control.

2. Preventing molten steel from re-oxidation and affecting billet quality. 3. Assuring molten steel be well distributed in molds to achieve optimal solidification.
