Electrofusion-recombined corundum bricks

The invention provides electrofusion-recombined corundum bricks. According to the electrofusion-recombined corundum bricks, AZS fused blocks or electro-fused AZS crushed bricks serve as a raw material, and a small amount of kaolin or alumina is added as a binder. When the temperature of the raw material is heated to a certain temperature, electro-fused AZS aggregates seep a glass phase, the glassphase forms mullite with the binder, brick bodies can be burnt, and the burnt temperature is 1,600 DEG C to 1,700 DEG C. Chemical composition fluctuation ranges of the recombined product provided by the invention are as follows: 50%w/w to 60%w/w of Al2O3, 20%w/w to 30%w/w of ZrO2 and 14%w/w to 20%w/w of SiO2. Compared with electrofusion products, the electrofusion-recombined corundum bricks have the advantages that the seepage of the glass phase is alleviated greatly, the seepage temperature is increased, high-temperature mechanical properties are relatively high, and particularly, the creep resistance and glass erosi
