The Ladle Nozzle for Continuous Casting of Steel is a critical refractory component designed to control the flow of molten steel from the ladle to the tundish during the continuous casting process. Made from high-purity alumina carbon, zirconia carbon, or magnesia carbon materials, the nozzle ensures smooth, precise, and stable steel flow, maintaining optimal casting quality and minimizing steel loss.
Manufactured with high-temperature sintering and advanced resin bonding technology, our ladle nozzles feature superior resistance to erosion, corrosion, and thermal shock, offering consistent performance and long service life even under severe operating conditions in steel plants.
