Steel Making Zirconia Inserts Refractory Tundish Nozzles
Steel making is an important part of metallurgy, and many Refractory are used in steel making, among which zirconium Refractory is one of the more advanced Refractory Refractory, it is used in the continuous casting of the steel-making link.
Steel making is an important part of metallurgy, and many Refractory are used in steel making, among which zirconium Refractory is one of the more advanced Refractory Refractory, it is used in the continuous casting of the steel-making link. Continuous casting requires high stability and corrosion resistance of the product.
The ZIRCONIA INSERT Refractory for steel-making made by our company has been guaranteed the stability of the product through the special optimization of the process and the strict tracing mechanism. Corrosion resistance, the product in the body and pores between the best adjustment, so that the use of products in the most perfect effect.
