Zirconium based sizing aluminum carbon inlet

In the selection of sizing nozzles for continuous casting, materials are the core determining their performance and application range. At present, zirconium based nozzles provide users with specialized solutions for different steel grades and process conditions.Material composition: High purity zirconia (especially stabilized zirconia) is used as the main raw material. Its advanced formula may incorporate oxides such as calcium and barium to optimize the microstructure.Ultimate corrosion resistance: Zirconia itself has a strong chemical inertness to molten steel and slag, especially when casting high oxygen, special alloy steel, or continuously for a long time, it performs far better than other materials, maintaining stable aperture and ensuring dimensional accuracy of continuous casting billets.High heat resistance and stability: It has a very high melting point (about 2700 ℃) and excellent thermal stability, and is not easily cracked or softened under severe temperature changes.Limit…
