Abstract

The invention relates to an aluminum spinel corrosion-resistant brick and a preparation method thereof. The aluminum spinel corrosion-resistant brick comprises a brick body. A noise reduction and shock absorption layer is fixedly installed outside the brick body, an original brick layer is fixedly installed outside the noise reduction and shock absorption layer, and a waterproof layer is fixedly installed outside the original brick layer. According to the aluminum spinel anti-erosion brick and the preparation method thereof, aluminum-magnesium spinel has high temperature resistance; the hardness of high-aluminum corundum particles is only lower than that of diamond; and the high-temperature mechanical strength, the slag resistance and the volume stability of high-purity magnesium sand are combined, so that the brick body and the original brick layer have higher refractoriness and high-temperature breaking strength, the exterior of the original brick layer is prevented from being peeled off, the high-purity magnesium sand and the sintered aluminum-magnesium spinel are adopted as main raw materials, the introduction mode of the material spinel is changed, after high-temperature sintering, the product has high-temperature resistance, erosion resistance, thermal shock resistance and low heat conductivity coefficients, can be used for a long time, and can be effectively cooled.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to an aluminum spinel anti-invasion brick and a preparation method thereof. Background technique [0002] Aluminum-magnesium spinel bricks are based on magnesia-alumina spinel, and their thermal shock resistance is better than that of magnesia bricks. The advantage of stone bricks is that they have good thermal stability. During use, they will react with clinker, and then form a thin layer of calcium aluminate protective layer on the surface of the bricks, making it difficult for liquid to penetrate, and its anti-stripping performance is better than that of direct bricks. It is better to combine magnesia chrome bricks. [0003] As the aluminum-magnesium spinel bricks are widely used, it is found that compared with the magnesium-chrome bricks, the fire resistance and shock resistance of the aluminum-magnesium spinel bricks are still difficult to achieve the effect of th...
