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.
The products can design and produce argon continuous purging and non-purging mono-stoppers as per the conditions of casting processes in steel mills. The nose mono-stopper can be AL2O3-C,MgO-C,Spinel or ZrO2-C based according to the types of steel to cast.The body and slag zone of mono-stopper are Al2O3 -C based.
Category of Refractory Functional :
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.
The mono-stoppers from Zhengzhou Xinyu can provide stable control of molten steel casting,good corrosion resistance, desired thermal shock resistance and high tenperature strength. It can last more 35 hours used for billet caster and more than 20 hours for slab caster. It is suitable for almost all steel casting from normal carbon steel,low carbon steel,ultra-low carbon steel,high Mn steel to high oxygen steel.
