Square billet Ladle Shroud Tundish Nozzle Slag Line Linder
Product Feature
1, Enhanced spitting hole material to ensure the product long time use of small reaming, strong scour resistance.
2, The composite material of imported zirconium - carbon slag line greatly guarantees the corrosion resistance of slag line.
3, Composite non-carbon lining can ensure the special requirements of clean steel, ultra-low carbon steel and other steels, and can effectively prevent blocking.
4, Compound nitride lining, not wetted by molten steel, excellent corrosion 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, Excellent aluminum-carbon body material, ensure good thermal shock stability of products, no cracking, no peeling.
7, Aluminum carbon free baking lower nozzle made with special formula and technology can be used in emergency.
8, Professional structure design, optimize mold flow field, improve casting billet quality.
