High Temperature Refractory Aluminum Carbon Long Nozzle
High temperature refractory Aluminum carbon long nozzle
Long nozzle is mainly used for the protection of the oxidation protection between ladle and tundish.. According to user needs can meet all the steel plant using a pouring time. Use of time greater than 10 hours, the leading domestic level, the notable feature is that it can not limit the use of the pouring times, and all free baking use.
As the chart shows:
1 different blowing argon structure, can choose according to the need.
2 ceramic anti oxidation glaze layer to prevent the effective carbon binding material is oxidized.
3 refractory fiber blanket to prevent heat loss when pouring steel.
4 The performance of aluminum carbon material 4 excellent corrosion resistance, no explosion.
5 high standard zirconium material ensures that the slag line has excellent corrosion resistance..
6 standard Magesia material to ensure the slag line part with excellent corrosion resistance of Ca steel.
7 the inner carbon free material guarantees the special requirements of the ultra low carbon steel, silicon steel, clean steel.
