Refractory Zirconia Nozzle Insert
Custom calcia stabilized zirconia nozzle insert manufactured by Anyang Changtai Silicon Industry. Designed for tundish metering nozzle in steel continuous casting. Resists molten steel erosion, minimizes bore wear, supports long sequence casting.
Products Description
The refractory zirconia nozzle insert is the functional core component fitted inside tundish metering nozzles. Produced by Anyang Changtai Silicon Industry Co., Ltd., it adopts high purity calcia stabilized zirconia raw material, formed by isostatic pressing and high-temperature sintering.
As the direct contact layer with high-temperature molten steel, this insert works together with alumina-carbon outer casing to form a complete flow control unit. It regulates steel throughput and sustains stable casting conditions. It is widely deployed on billet and bloom continuous casting machines for various carbon and alloy steel grades.
Product Strengths
- Anti-erosion and anti-slag performance, extending the continuous casting campaign length
- Controlled bore wear rate, helping maintain stable mold level and uniform casting speed
- Restrains alumina deposition on inner surface, lowering the risk of nozzle blockage and unplanned stops
- Reliable thermal shock resistance, withstand sharp temperature changes during ladle switching
- Low volatile content at high temperature, less contamination and inclusion defects on cast steel
- Strict dimensional control on bore, taper and outer profile, good matching for mass assembly
- Formulation tunable for high alloy steel, high oxygen steel and long-run casting scenarios
