Zirconia Refratech manufactures high-performance zirconia inserts and tundish/composite metering nozzles for tundish gate system components to provide exemplary performance and reduce steel-making costs.
Zirconia insert is made of monoclinic zirconia stabilized with magnesia or calcia by a unique process. Then the powder is wet pressed at optimum pressure, and then the green nozzle is sintered at a high-temperature furnace.
Characteristics: The zirconia insert nozzle have high strength, erosion and corrosion resistance, good thermal shock vibration properties, low diameter expansion rate, and long service life.
Application: The zirconia insert nozzle has its application in continuous casting of tundish billets, blooms, rectangular billets, and small slabs for pouring steel.
It comprises a zirconia insert (inner zirconia nozzle) and an outer body such as high-grade alumina-carbon. It is manufactured by a unique process of directly pressing the outer body around the zirconia nozzle without using the cement joining, providing no risk of steel leakage between the inner and outer body.
Characteristics: The metering nozzle is designed in such a way to provide controlled and uniform casting speed, long casting sequence time, low diameter expansion rate and resistance to oxygen stranding.
Application: Zirconia tundish metering nozzle is a high-performance nozzle used in the continuous casting of steel billets.
