Long nozzle (or protection tube) is used between ladle and tundish tenperature strength/Good corrosion 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.

Zhengzhou Xinyu can design and produce pre-heating required and heating free shrouds

according to the site needs and condition of steel mill.

Zhengzhou Xinyu can also provide non-protective fired and pre- heating free shroud. Under

special firing process,the shroud generates a decarbonized layer with micropores,which can give better thermal insulation and also create favorable temperature gradient for better thermal shock resistance and also abrasion resistance.

Category of Refractory Functional :

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

Features:

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.

This product is mostly suitable for low and ultra- low steel and alloy steel productionn particular.
