Zirconium Oxide Tundish Nozzle Has High Refractoriness, Good Thermal Shock Performance, Corrosion Resistance And Erosion Resistance

The zirconia nozzle is a kind of nozzle auxiliary container which is more common in the continuous casting process. In order to reduce the damage of the nozzle during the continuous casting process, zirconia is often used as the material of the nozzle. This kind of nozzle not only has the advantages of high temperature resistance and corrosion resistance of molten iron, but also has various shapes. You can choose different types of nozzles according to your actual needs. The appearance of zirconia nozzles also has great advantages for continuous casting.

The zirconia nozzle is one of the tundish refractory materials in the continuous casting process. It is mainly used for 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 zirconia nozzle is made of stable zirconia after being stabilized by a special process, and is formed by high-pressure molding and high-temperature firing. It can be customized according to different steelmaking environment and usage requirements of users. Zirconium oxide nozzle characteristics: The sizing nozzle has the characteristics of high refractoriness, good thermal shock performance, corrosion resistance, erosion resistance, small diameter expansion change and long service life.

The zirconia nozzle is made of highly corrosion-resistant refractory material, and the diameter of the nozzle remains basically unchanged throughout the continuous steel casting process. It is used for the plugless casting system of small billet continuous casting intermediate tank, which can ensure a stable pulling speed during the continuous casting process.

According to different steel-making pouring processes, the type of nozzles selected is also different. Commonly used are zirconia nozzles, quick-change sizing nozzles, etc. The application of these nozzles helps to improve the efficiency of continuous casting and reduce the nozzles in use damage. After all, the zirconia nozzle is a container that accepts molten iron. Before and after use, the nozzle should be well maintained to reduce the loss of the nozzle in the air and help to increase the life of the nozzle.
