Submerged Entry Nozzle

Submerged Entry nozzle are generally used together with other function refractories, there are structures as listed:

Monoblock stopper with submerged Entry nozzle

Tundish metering nozzle with Submerged Entry nozzle

Monolithic tundish nozzle with submerged Entry nozzle

Exhangeable tundish nozzle with Submerged Entry nozzle

Materials: Alumina carbon type with zirconia slag zone

 

 

 

 

 

Producing process: Grinded powder--mixing-- shaped with isostatic press--fired in shuttle kiln---anti-oxidant coating---inspection and packaging

 

 

 

The main feature of refractory submerged entry nozzle is their high temperature resistance. At extremely high temperatures, traditional metal nozzles are difficult to meet the demand for discharging liquid metal, and refractory submerged entry nozzles were developed to solve this problem.

The unique structure of the refractory submerged entry nozzle makes it less susceptible to melt erosion. After being exposed to high temperatures, traditional metal nozzles are easily susceptible to chemical erosion and physical damage, and this cross-erosion has a very negative impact on the life of production equipment. The refractory submerged entry nozzle is different. It has strong corrosion resistance and can withstand the impact and erosion of high-temperature melt.

Refractory submerged entry nozzle last longer than traditional metal spouts. The metal nozzle will be corroded and hardened by high-temperature liquid metal in a short period of time, causing the leakage rate of the metal nozzle to increase sharply and must be replaced in time. The refractory submerged entry nozzle uses refractory materials with high corrosion resistance chemical properties, so its service life is much longer, which can fully ensure the stability and continuity of production equipment.

Refractory submerged entry nozzles also have good safety features. With the continuous advancement of industrial technology, safety issues have become an issue that all walks of life must pay attention to. The refractory submerged entry nozzle is made of materials with very corrosion-resistant chemical properties. It does not produce harmful substances during the production process and avoids harm to personnel and the environment. It can be said to be a very safe equipment.

There are different structures of the submerged entry nozzles for difficult applications, including nozzles with side holes, straight nozzles, bowl shape nozzles, nozzles for thin slabs, quick-replace nozzles etc.
