Besides having the same eutectic of fused cast AZS brick 33#, Fused cast AZS brick 36#, due to increasing much chain-type zircon oxide acicula,at the sae the content of glass phase is reduced,therefore,the erosion resisting of fused cast AZS brick 36# is further strengthened, so, it is suitable for the area where melting glass flows faster and the temperature is higher.
