Zirconia Ceramics for Continuous Casting
Zirconia-based ceramics are widely used in modern steel continuous casting for their thermal shock resistance, corrosion resistance, high-temperature strength, and erosion resistance. These properties make them essential for high-temperature melt flow control, enhancing production stability, reducing operational risks, and improving steel quality.
Product Examples and Applications:
1) Sizing Nozzle
A zirconia sizing nozzle maintains constant static pressure in the tundish and regulates molten steel flow into the crystallizer. The nozzle’s orifice size controls flow rate, stabilizing the casting process and ensuring consistent billet formation. It is also adaptable for other molten metals.

2) Ladle Slide Plate with Zirconia Inlays
Zirconia plates and rings are embedded in ladle slide plates using high-temperature adhesives. This improves surface strength, extends service life, and reduces costs, while meeting the needs of high-oxygen steel, high-calcium steel, and high-manganese steel casting.

3) Converter Slag-Blocking Slide Plate Inlays – Zirconia Plates and Rings
Zirconia rings are installed in upper slide plates and plates in lower slide plates to:
- Reduce slag entering the ladle
- Improve specialty steel yield and reduce phosphorus reversion
- Increase alloy utilization, lower deoxidizer and modifier consumption, and cut production costs
- Minimize inclusions, improving steel purity
