Zirconia tundish nozzles, with their exceptional resistance to high temperatures and abrasion, are an ideal choice for the casting industry. These nozzles are made of pure zirconia, which not only ensures dimensional stability under harsh conditions but also provides excellent resistance to corrosion and erosion caused by contact with molten metals.
Key advantages include optimal performance in molten metal flow control and extended service life. Manufactured in compliance with international standards, zirconia nozzles contribute to higher productivity and reduced maintenance costs.
Zirconia tundish nozzles, with their special formulation and high chemical purity, are designed to operate in environments exceeding 1600°C. Their robust composition provides outstanding resistance to mechanical wear and chemical corrosion caused by direct contact with molten steel.
With excellent dimensional stability and a precisely engineered internal channel, these nozzles ensure a uniform molten metal flow, thereby enhancing the quality of the final product. Manufactured under strict international standards, zirconia nozzles help extend equipment service life and minimize production downtime.
Today, in many steel plants equipped with continuous casting systems, tundish nozzles with long service life have particular importance. To maintain a constant casting speed, which is generally dependent on the nozzle bore diameter, it is necessary to use zirconia nozzles with very high resistance to erosion and corrosion.
The zirconia inserts are manufactured by the isostatic pressing method with an optimized thickness, enabling them to withstand high thermal stresses. In addition, the zirconia used in the body is stabilized through special processes and possesses a high sintering density.
In the pressing method, the zirconia insert is co-pressed directly into the well block seat without the use of any mortar or adhesive, thereby achieving the highest mechanical strength at elevated temperatures. In the precast method, the well block is cast around the zirconia insert using hydraulic-bonded castable material.
Zirconia tundish nozzles, with their exceptionally high thermal resistance, not only withstand the continuous flow of molten steel but also ensure dimensional stability under severe operating conditions. This feature provides outstanding durability against chemical corrosion and erosion caused by high-speed flow, making them the ideal choice for tundishes in continuous casting lines, where reduced downtime and lower maintenance costs are critical.
