Zirconia inserts for tundish metering nozzles are premium ceramic parts intended to improve the effectiveness and durability of tundish metering nozzles during steelmaking operations. These inserts are crafted from zirconia, a resilient and heat-resistant material known for its exceptional resistance to wear and thermal shocks.

 

 

Zirconia is a type of ceramic material that possesses excellent properties such as high melting point, thermal shock resistance, and chemical inertness. These characteristics make it well-suited for use in harsh steelmaking environments.

 

The zirconia insert is a component that is placed inside the tundish metering nozzle. It acts as a wear-resistant barrier, protecting the nozzle from erosion caused by the high-temperature molten steel flow. The zirconia insert helps to extend the lifespan of the nozzle, reducing the frequency of maintenance and replacement.

 

Additionally, the smooth surface of the zirconia insert helps to improve the flow control of molten steel, ensuring a more precise and consistent flow rate. This is important for achieving uniform casting and maintaining the quality of the steel product.
