Refractory Brick

1. High alumina brick: the content of Al2O3 is more than 75, the refractoriness is higher than that of clay brick, the corrosion resistance is good, and it is suitable for the burned zone of cement kiln for use Refractory brick.Refractory brick Long life but high price2. Dolomite brick: it has good performance of hanging kiln skin and good resistance to erosion. However, some of the bricks contain f-cao, which is easy to be hydrated and difficult to transport and keep3. Magnesite-chrome brick: it is good to hang the shell of the kiln, and is mostly used in the sintering belt. Its disadvantages are poor thermal shock resistance and high toxicity of Cr4. Spinel brick: it is mainly used for excessive belt, with good seismic performance and reducing resistance, but slightly less refractoriness
