Product Description

Upper nozzle/Used for tundish /long service life/Resistance to erosion/Good thermal shock resistance


Product description:


Functional refractory is a kind of special refractory formed with the development of continuous casting technology in iron and steel metallurgy industry.Rather, it should be called metallurgical functional refractory.Functional refractory current mainly includes the refractory products have: slide gate, tundish, overall stopper, submerged nozzle 3 big (cc), air brick and sizing nozzle, their key parts in the continuous casting process are play an important role, such as curtains, and the roles of blowing air agitation, prevent secondary oxidation protect casting, decided to molten steel flow field distribution in the crystallizer, etc.The use of these refractory materials is an important prerequisite for the continuous casting process.

According to customers' needs,The products can provide ordinary,quick exchangeable and gas purging upper nozzles. The bowl part of the nozzle is available with Al2O3-C Mgo-C and spinel-C based and the main body is al2O3-C based.


Category of Refractory Functional :

  • Ladle shroud
  • Mono-stopper
  • Upper nozzle
  • Submerged entry nozzle
  • Zr2O metering nozzle


Function compared with the conventional refractory refractory, its characteristic is: in the process of use of metallurgical process of special functional role, often as a single element or some combinations of auxiliary refractory products, the creation of a special production process, material choice and high-grade refractory materials are almost has a high performance, such as magnesium carbon materials, aluminum zirconium materials, carbon materials, just the quality of the jade, zirconia, etc, the function of the current application of refractories containing carbon refractories are mostly.
