Metering nozzle is composed of inner zirconia and outer high alumina, produced by reasonable size and high temperature sintering process. Metering nozzle is one of the refractory materials used in billet continuous casting. It plays a role in controlling the flow of molten steel. The molten steel flows into the mold through the sizing nozzle at a constant speed and stability, which is a necessary condition to ensure the normal operation of continuous casting. The use of metering nozzle ensures continuous casting for a long time. Metering nozzle has good corrosion resistance and thermal stability, and will not block, fall off, crack and expand during use, and can meet the requirements of steel mills for high-quality products.
