High Density Zirconia Nozzle
Since its establishment in 2011, the company has developed a variety of Zirconia nozzles which are suitable for the environment of steel making and continuous casting, among them, the high bulk density Zirconia nozzle is one of the most excellent products in our company.
Since its establishment in 2011, the company has developed a variety of Zirconia nozzles which are suitable for the environment of steel making and continuous casting, among them, the high bulk density Zirconia nozzle is one of the most excellent products in our company. Due to the higher density of the product, it is more resistant to corrosion, and the heat stability of the product is not affected by the higher density of the product.
