Product Description Product DescriptionJISteel Factory Long Working Life Tundish Refractory Submerged Entry NozzleThe submerged nozzle is a refractory casing installed at the bottom of the tundish and inserted below the liquid level of the mould in the continuous casting equipment.The submerged nozzle plays the role of protecting the molten steel from being oxidized by the ambient air when it flows into the mould from the tundish, and also plays the role of evenly distributing the molten steel into the mould and controlling the flow state of the molten steel in the mould. The submerged nozzle is well received by users for its excellent performance such as good slag resistance, anti-clogging, long life and low accident rate.The basic requirements for the material of the submerged nozzle are good resistance to molten steel dissolution, strong resistance to slag erosion and good thermal shock resistance. The commonly used materials are fused silica and Al2O3-C.Detailed PhotosProduct Parameters Chemical and Physical Technical DataChemical PropertiesItemDataAL2O3<=0.072Fe2O3<=0.0045Na2O3<=0.0038K2O<=0.0035SiO2<=98Physical PropertiesBulk Density (g/m3)>=1.9Apparent Porosity (%)<=12Cold Crushing Strength (Mpa)>=55Cold Bending Strength (Mpa)>=25Thermal Conductivity (W/m.k)0.8Thermal Expansivity (oC-1)<=0.9x100-6Crystallinity (Vol %)<=1Using Temperature (oC)1600Our AdvantagesCompany ProfileFounded in 2004, JI Steel has 20 years of professional experience in the metallurgical industry and is committed to the design, production, research and development of materials in the metallurgical and steel industry, and provides a series of high-quality, innovative and cost-effective products and solutions for steel mills.
