Chrome corundum brick characteristics
Chrome corundum brick refers to alumina and Cr2O3 content is greater than 90%, corundum as the main crystalline phase of refractory products, with good chemical stability, acid or basic slag, metal and glass liquid have strong resistance, mainly used in the furnace bottom, furnace door and furnace cylinder and other parts, heating furnace slide brick and steel groove brick are the use of chrome corundum brick.
Due to the Al2O3-Cr2O3 binary phase diagram, it can be seen that Al2O3 and Cr2O3 can form continuous solid solutions, and no eutectic products are produced. Therefore, the addition of Cr2O3 to high-purity corundum materials, no matter how much is added, will not only reduce the fire resistance of the material, but improve the fire resistance of the material. The refractoriness and load softening temperature of chrome corundum brick are both greater than 1750℃, which are better than high purity corundum products.
