Collector Nozzles are critical refractory flow-control components installed beneath the slide gate assembly of steel ladles to safely transfer molten steel from the ladle to downstream casting systems. These precision-engineered nozzles form the final outlet section of the ladle flow-control system and are designed to withstand continuous exposure to molten steel, high casting temperatures, thermal cycling, and severe erosion conditions.
Manufactured from advanced refractory materials such as Alumina-Carbon (Al2O3-C), Zirconia-Graphite, Alumina-Zirconia-Carbon (AZC), and other specialized compositions, Collector Nozzles provide excellent resistance to steel erosion, slag attack, thermal shock, and oxidation. Their performance directly influences casting stability, steel cleanliness, nozzle life, and overall operational reliability in continuous casting applications.
