Elongated Long Refractory Nozzle Ladle Shroud Al2O3 Pipe Shape
Product Feature
1, Adopt the advanced bare firing technology, the nozzle can avoid baking and change the use of multiple furnaces, good thermal shock stability and scour resistance
2, Low carbon long nozzle can meet the requirements of long life
3, Composite non-carbon lining can ensure the special requirements of clean steel, ultra-low carbon steel and so on.
4, The composite zirconium-carbonaceous slag line has better slag erosion resistance.
5, High strength anti-oxidation coating, can form liquid protective film in the range of 600~1200℃, protect carbon from oxidation, prolong the service life.
6, The air seal device with different structure can be selected according to the need at the connection with the water outlet of the big bag to prevent oxygen and nitrogen absorption effectively.
