125 Square Tundish Zirconia Nozzle
The utility model relates to a 125 square Zirconia Tundish nozzle, which is a tundish nozzle with an outline size of 125 mm. The product is a composite Refractory with an outer layer of alumina Refractory and an inner layer of zirconia Refractory.
The utility model relates to a 125 square Zirconia Tundish nozzle, which is a tundish nozzle with an outline size of 125 mm. The product is a composite Refractory with an outer layer of alumina Refractory and an inner layer of zirconia Refractory.
Compared with the assembly method of fire mud bonding, this assembly method greatly reduces the risk of molten steel flowing out of the gap between the zirconia insert and the aluminum carbon outer layer during use.
The nozzle of 125 Square Zirconia tundish can be divided into two types, one is non-fired type and the other is fired type. They have the same service life, but they are not quite the same, depending on the steelmaking environment.
Product features: Zirconium upper nozzle has the characteristics of high strength, good thermal vibration performance, corrosion resistance, erosion resistance, low diameter expansion rate, and long service life.
Customizable: Specific parameters and dimensions can be processed according to different steelmaking environments and usage requirements of users.
