Glass kiln material flowing nozzle brick and preparation method thereof

The invention relates to a high-temperature material, in particular to a glass kiln flow nozzle brick and a preparation method thereof, the material of a working layer does not have a low-melting-point glass phase, the content of zirconium dioxide is high, and the sintering temperature is high, so that the erosion resistance is far better than that of an electric melting AZS protective layer which is a non-working part of the nozzle brick, the electric melting AZS protective layer is not in contact with molten glass, and the effects of setting off and protecting the working layer are achieved; the composite material nozzle brick is simple in structure and low in manufacturing cost, so that the total cost of the composite material nozzle brick is slightly higher than that of electric smelting AZS, and based on the unique performance of the composite material nozzle brick, compared with the electric smelting AZS material nozzle brick, the composite material nozzle brick is long in service life and plays an impo
