Metering Nozzles are precision-engineered refractory flow-control components used in tundish systems to regulate and maintain a controlled flow of molten steel into continuous casting moulds. By providing a fixed and accurately designed bore diameter, these nozzles help achieve stable steel flow rates, consistent casting conditions, and improved product quality throughout the casting sequence.
Installed at the bottom of the tundish, Metering Nozzles operate under severe thermal, chemical, and mechanical stresses. They are typically manufactured from high-performance refractory materials such as Alumina-Carbon, Zirconia-based compositions, and specialized wear-resistant ceramics that offer excellent resistance to thermal shock, erosion, steel penetration, and clogging. Their performance is critical for maintaining casting productivity and ensuring dimensional consistency in finished steel products.
