Microporous corundum brick is applied to blast furnace ceramic cup masonry. It is produced by adopting all technologies, processes and microporous technology. The product has high high high temperature strength, toughness, alkali metal resistance, slag resistance and hot metal corrosion resistance. The average pore diameter of the product is small, the percentage of pore volume < 1um is high, and it is almost airtight brick
The main raw material of microporous corundum brick is fused corundum with special additives, resin as binder, special microporous production process, molding, high-temperature firing, and fine grinding and pre assembly by machine tool to ensure the requirements of masonry brick joint. The three technical indexes of alkali resistance, slag erosion resistance and micropore of the product are better than those of French brown corundum castable
The average pore diameter of microporous corundum brick is ≤ 0.5um, and the pore volume less than 1um is ≥ 70%
