Customized zirconia nozzle tundish metering nozzle refractory

This product is suitable for continuous cast tundish open cast steel. The zirconium insert is made of high-purity zirconia, which is formed by high-pressure molding and sintering at high temperature. The outer is made of corundum and high-quality aluminum vanadium. It is formed by high pressure molding and baked at low temperature. The two are bonded with corundum mud, and the product's corrosion resistance and thermal shock stability have reached the domestic advanced level, which can fully meet the needs of various billet continuous casting. Tundish upper nozzle It is located within the tundish lining and conveys steel to the controlling exchangeable nozzle,which determines the steel flow. The stationary nozzle must be capable of withstanding long sequence times. Our Upper nozzle that incorporates a ultra-high densityLKZN-M or LKZN-H insert. The insert provides excellent erosion resistance and can provide extended casting sequence times. The lower surface of the stationary nozzle is ground to exacting tolerances to ensure maximum surface contact between the two nozzle components. Tundish lower nozzle It is located within an assembly that is fixed to the bottom of the tundish.The design of the exchangeable nozzle can vary according to the system manufacturer. We supplying a range of zirconia inserts and composite nozzle designs for the exchangeable metering of steel. Zirconia inserts can be supplied for on-site assembly into metallic holding blocks where cementing, grinding, size banding and on site drying are required prior to use. It was manufactured by both cast process of fine grained alumina method or presse process.
