AG (Alumina-Graphite) tube refractories for continuous-casting processes

Krosaki Harima Corporation manufactures various excellent continuous casting nozzles containing alumina-graphite as the major component, maintaining a large share in domestic market. The corporation supplies nozzles provided with appropriate materials and design in compliance with their respective operational conditions such as nozzle preheating or kinds of steel.

Ladle shrouds for excellent durability and elaborated function are characterized by

Corrosion resistance
Repetitive hot service with preheating (The longest durability in Japan, 1800 minutes of casting, was recorded by the corporation's product.)

Monoblock stoppers for excellent durability and elaborated function are characterized by

Corrosion resistance
Reliability of inert gas bubbling (stable gas blowing into molten steel without gas leakage)

Tundish nozzles for excellent durability and elaborated function are characterized by

Abrasion resistance at coupling point (for stable control of the molten steel level in the mold)
Inert gas bubbling available at any flow rate and from any requested point of either the coupling point or of the inner bore surface
Reliability of inert gas bubbling (stable gas blowing into molten steel without gas leakage)

Submerged nozzles for excellent durability and elaborated function are characterized by

Corrosion resistance at the portion in contact with casting powder (The longest durability in Japan, 1800 minutes of casting, was recorded by the corporation's product.)
Various configurations to prevent the nozzle clogging during stable casting:
e.g., Submerged nozzle provided with inert gas bubbling from inner bore surface
e.g., Submerged nozzle provided with bore inner lining of being less adhesive
Various configurations to prevent a biased stream during stable casting:
e.g. Submerged nozzle provided with oval protuberances on inner bore surface
e.g. Submerged nozzle provided with "Fin" enhancing molten steel rotation in the bore to prevent a biased stream
Special flat section nozzles for application in thin slab casting
