Collector Nozzle
A collector nozzle is a critical refractory component used in continuous casting to distribute molten metal evenly into multiple molds. It is typically located at the end of the tundish, ensuring controlled flow, reduced inclusions, and minimized air ingression during casting

Key Properties of Collector Nozzles
1. Material Composition: High-alumina fireclay, zircon-based ceramics, or magnesia-carbon refractories.
2. Density: Typically ranges from 2,500–3,100 kg/m³, depending on material type.
3. Thermal Conductivity: Optimized for heat preservation and flow uniformity.
4. Maximum Operating Temperature: Up to 1,750°C, ensuring durability in molten metal environments.
5. Flow Control: Designed with precision-engineered ports to regulate molten metal distribution.
Applications of Collector Nozzles
Steel Production: Ensures uniform metal flow in slab, billet, and bloom casting.
Aluminum & Copper Casting: Used in non-ferrous metal industries for controlled pouring.
Specialty Alloys & Foundries: Enhances casting efficiency and reduces defects.
