The continuous casting process relies on a delicate balance between smooth flow control and maintaining steel quality. Tundish nozzles play a critical role in this equation, and Zirconia (ZrO2) insert nozzles offer a compelling solution for enhanced performance.

What is a Tundish Nozzle with ZrO2 Insert?

A tundish nozzle is a refractory component positioned within the tundish, a holding vessel that feeds molten steel into the continuous casting mold. The nozzle acts as a controlled outlet, guiding the steel stream and influencing flow rate. Tundish nozzles with ZrO2 inserts feature a two-layer design:

• Outer Body: This is typically constructed from a cost-effective refractory material like high-grade alumina or alumina-carbon.
• Inner Insert: Made from Zirconia (ZrO2), a highly engineered ceramic material known for its exceptional properties.

Benefits of Tundish Nozzles with ZrO2 Insert:

• Enhanced Erosion Resistance: Zirconia boasts superior resistance to erosion from the molten steel stream, extending the lifespan of the nozzle and minimizing the risk of premature failure.
• Improved Flow Control: The smooth and uniform surface of the ZrO2 insert facilitates more precise flow rate control, leading to a more stable casting process and improved product quality.
• Reduced Casting Defects: Consistent flow control and minimized erosion contribute to a cleaner steel stream, reducing the occurrence of casting defects like surface imperfections.
• Extended Casting Sequences: The increased durability of the ZrO2 insert allows for longer casting sequences before nozzle replacement is required, optimizing production efficiency.
