The refractory ladle collector nozzle is one of the important equipment used for molten steel casting in the steel manufacturing process. Its key property is that it needs to maintain stable operation under high temperature and high pressure conditions and ensure the fluidity of molten steel.
product description
There are three main types of refractory ladle collector nozzles: alumina-carbon (AC) type, carbon silicide (SiC) type and aluminum (AZS) type. Each model has its own unique physical and chemical properties and is suitable for different production scenarios.
1. Alumina-carbon (AC) type
The AC type refractory ladle collector nozzle is mainly composed of alumina and high-purity carbon. Its main features are low cost and stable chemical properties, so it has been widely used in steel manufacturing production. However, compared with other models, AC type products have lower mechanical strength and are prone to slag problems.
2. Carbon silicide (SiC) type
The SiC type refractory ladle collector nozzle is mainly composed of carbon silicide. Its main features are good high-temperature stability, no slag in the skin layer, and good sliding effect. Therefore, it is widely used in high-demand scenarios of steel refining. However, SiC products also have problems such as easy wear and high cost.
3. Aluminum (AZS) type
The AZS type refractory ladle collector nozzle is mainly composed of alumina, zirconia and silicon. Under harsh conditions such as high temperature and high pressure, AZS products can slide stably for a long time and also have good wear resistance and fire corrosion resistance. In addition, the manufacturing cost of AZS-type products is relatively low, so it has also been favored by many manufacturers.
Advantage introduction
1. Stable performance
Refractory ladle collector nozzle products are produced using high-quality raw materials. After strict production process deployment and quality control, the product's performance is stable and meets the usage requirements.
2. High temperature stability
Refractory steel ladle collector nozzle products perform well in harsh environments such as high temperature and high pressure, can slide for a long time, and are not prone to penetration. Therefore, production efficiency can be greatly improved in the steel manufacturing process.
3. Wear-resistant and corrosion-resistant
The surface of the product uses a special coating process, which gives full play to the wear-resistant and corrosion-resistant properties of the material. It is not easy to be worn and damaged during the production process, ensuring the long-term stable use of the product.
4. Safe and reliable
During use, the refractory ladle collector nozzle can stably discharge the molten steel in the furnace, ensuring the safety and reliability of the production process. At the same time, it is not easily corroded and burned, and has high safety.
Applications
The refractory ladle collector nozzle is one of the indispensable equipment in the steel manufacturing and production process. It is widely used in steelmaking, ironmaking, casting and other scenarios. Specific application scope includes: converter, electric furnace, intermediate frequency furnace, electroslag furnace, melt protection casting and other fields.
