Only as a personal opinion of Zhengzhou Juda Refractory Materials: The raw materials used in chrome corundum brick refractory brick products are alumina and chromium oxide in a certain proportion, α-Al2O3 is the raw material, and an appropriate amount of chromium oxide Cr2O3 is added Powder and chromium corundum clinker fine powder are shaped and fired at high temperature. It can be used as the lining of glass kilns, waste incinerators, gasifiers, etc. It can also be used as the lining of heavy metal smelting reverberatory furnaces or reaction furnaces.
Personally think: Chromium corundum bricks and carbon will not react at constant high temperatures. According to the properties of refractory materials, both materials are neutral materials. However, chromium belongs to Group VIB in the periodic table of elements. The atomic number of chromium is 24 and the atomic weight is 51.9961. It has high corrosion resistance. In the air, even if In the red hot state, oxidation is also very slow. Insoluble in water
Carbon has the element symbol C, atomic number 6, and atomic weight 12.01, belonging to group IVA. Therefore, I personally believe that these two materials do not melt when used at high temperatures to resist corrosion.
