Zirconium Sizing Nozzle Description：
Zirconia nozzle is one of the tundish refractory materials in continuous casting process. It is mainly used in billet continuous casting and can control the flow of molten steel. The sizing nozzle must have excellent thermal shock resistance and erosion resistance to ensure that the molten steel can flow into the mold uniformly and steadily through the sizing nozzle, so as to ensure the normal progress of the continuous casting process and increase the production efficiency. The zirconium sizing nozzle is stabilized by special zirconia, which is formed by high-pressure molding and high-temperature firing after being stabilized by a special process.
Zirconia nozzle is one of the tundish refractory materials in continuous casting process. It is mainly used in billet continuous casting and can control the flow of molten steel. We manufacture complete range of zirconia metering nozzles used for the continuous casting of steel as a tundish refractory. Nozzles can be supplied as a solid piece or with outer high alumina body. The nozzles have high thermal stability, anti-erosion and erosion resistance, and can meet the needs of various small billet casting.
Zirconia nozzles are manufactured from different type of raw materials, chemical content, physical specifications and sizes depending on the service application. We choose high quality zirconia as the main material. In order to improve the thermal shock stability, MgO, Y2O3, CaO stabilizing agents are added to the mix. These agents also improve the life of use. our zirconia metering nozzles are used by our customers with highly satisfaction.
Zirconia Nozzles can be divided into 3 groups such as:
Metering Nozzle Inserts
Exchangeable (Lower/Outer) Nozzle
Stationary (Upper/Inner) Nozzle
Zirconium Sizing Nozzle Features:
1. Stable product quality, all the Slide Gate Series products can meet the national standards;
2. A long service life in actual use and good reputation at home & abroad
3. The slide plates have the advantages of high strength, good erosion resistance, thermal shock resistance and good stability etc..
4. Mainly used in large and medium-sized ladle.
Metering nozzles is a Refractories For Tundish and also a Tundish Nozzle Material for Tundish Nozzle Uses, are mainly with zirconium inserted, featuring high refractoriness, and low expansion rate, superior resistance to erosion/corrosion and thermal shock and long service life. According to customers’ different needs, our factory can provide the Nozzle Meter with various sizes and specifications.The steelmaking of tundish nozzle core,it’s a brick refracory material casting tundish nozzle and a high strength high toughness tundish nozzle.
Based on functions, tundish nozzle,submerged nozzle manufactured by our company are classified into plug-in type, hanging type and fast renewal type; and based on material quality, nozzles mainly classified into aluminum carbon, zirconium carbon and magnesia carbon. Tundish nozzle, submerged nozzle enjoys performances of purifying liquid steel, prevent liquid steel oxidation, with good liquid steel washing resistance and erosion resistance.
