Our Long Nozzles are refractory for pouring molten steel from a ladle to a tundish, in order to prevent oxidation, align its flow and prevent splash.

Their requirements include:
- Resistant to spalling at high temperature
- Resistant to erosion
- Stable operation for a long time
and sometimes
- Safe operation without preheating.

Today’s operating conditions are getting harder such as interval usage.
We select suitable materials and prepare various shapes, according to customers' needs, such as alumina-graphite only, combination of alumina-graphite, zirconia-graphite and etc.
