The invention discloses a fused cast zirconia-corundum refractory brick with zero glass phase seepage. The fused cast zirconia-corundum refractory brick comprises the following components in percentage by weight: 59.6%-65.9% of Al2O3, 15.1%-17.7% of ZrO2, 16.4%-17.2% of SiO2, 2.2%-2.5% of Na2O and 0.2% of Fe2O3 and TiO2 in total. A preparation method comprises the following steps during preparation: S1, preparing the following raw materials in percentage by weight: 60-64% of aluminum oxide, 23-27% of zircon sand, 7-9% of refined quartz and 4-4.6% of sodium carbonate; S2, uniformly mixing and stirring the raw materials in the step S1 to obtain a mixture; S3, adding the mixture into a corundum electric arc furnace for melting; and S4, casting and annealing the molten feed liquid to obtain the fused cast fused zirconia-corundum refractory brick. The refractory brick can realize zero glass phase seepage, has excellent performance, and ensures the upper structure of a glass kiln; the manufacturing process is easy to implement and suitable for popularization and application.
本发明公开一种零玻璃相渗出的熔铸锆刚玉耐火砖，按重量百分比包含以下组分：Al2O3占59.6～65.9%、ZrO2占15.1～17.7%、SiO2占16.4～17.2%、Na2O占2.2～2.5%、Fe2O3与TiO2合计占0.2%；在制备时按照以下步骤进行：S1、按以下重量百分比准备原料：60～64%的氧化铝、23～27%的锆英砂、7～9%的精石英以及4～4.6%的纯碱；S2、将步骤S1的原料混合搅拌均匀得到混合料；S3、将混合料加入刚玉电弧炉内进行熔化；S4、熔化后的料液经过浇铸与退火得到所述熔铸锆刚玉耐火砖；本发明耐火砖能够实现零玻璃相渗出，性能优异，保证玻璃窑炉上部结构；同时制造工艺易于实现，适于推广应用。
