Fused zirconia corundum low-seepage brick production method
The invention relates to a fused zirconia corundum low-seepage brick production method which can effectively reduce seepage amount of a fused zirconia corundum brick glass phase. According to the technical scheme of the fused zirconia corundum low-seepage brick production method, a raw material is prepared by evenly mixing, by weight, 20-30% of clinker and 70-80% of raw meal, wherein the clinker is prepared by evenly mixing, by weight, 1.3-1.6% of sodium oxide (Na2O), 32-33% of zirconium oxide (ZrO2), 14-16% of silicon dioxide (SiO2) and 50-52.5% of aluminum oxide (Al2O3); the raw meal is prepared by evenly mixing, by weight, 15-30% of zircon sand, 50-77% of forged alumina powder, 7-18% of desilicated zirconia and 1-2% of sodium carbonate (Na2CO3). According to a produced fused zirconia corundum low-seepage brick, the seepage amount of the glass phase under the condition of 1500 DEG C*4 h is reduced to 1.2%, and accordingly chemical replacement between the brick and high-temperature glass melt in use is reduced, erosive damage to a material is reduced, and the service life of the fused zirconia corundum brick is greatly prolonged.
