The new matrix optimization theory and compactness theory have been applied to develop the long life ladle upper nozzle refractory series. In the pouring process, generally after pouring one or two furnaces of molten steel, the lower slide and the lower water outlet must be replaced and reassembled. The sealing protection is made of fibrous or mastic gasket to ensure the high cleanliness of the molten steel and the uniformity of the internal quality of the billet.

For steel mills, the service life of the top water outlet will have a significant impact on the service life of the bottom, and the service life of the bottom directly affects the comprehensive age. The refractory material used for sliding nozzle should have high high temperature strength, especially the ladle seat brick, which can withstand the mechanical damage and the erosion of molten steel when replacing the nozzle brick. The product has the characteristics of excellent thermal shock stability, outstanding oxidation resistance and strong anti-erosion ability. Use time is long. Ladle water outlet is used to output molten steel in ladle. The ladle water outlet comprises an upper water outlet, a skateboard and a lower water outlet arranged successively from top to bottom. The skateboard can slide and a steel water hole is arranged on the skateboard.

Advantages of ladle Upper nozzle refractory:

It has the characteristics of strong thermal vibration resistance, good erosion resistance, stable quality and long life.
