High-purity compact calcium hexaluminate series refractory material and preparation method thereof
The invention belongs to the technical field of refractory materials, and discloses a high-purity compact calcium hexaluminate series refractory material, a preparation method thereof and a working lining using the high-purity compact calcium hexaluminate series refractory material. The mixing proportion of a CaO-containing raw material, an Al2O3-containing raw material and a ZrO2-containing raw material is adjusted according to the chemical components of a final product; the ratio of the chemical components Al2O3, CaO and ZrO2 is (45.5-95.5%): (2.0-8.4%): (0-50%) according to the mixing ratio, the raw materials are put into a high-temperature furnace and a mold to be subjected to hot press molding sintering, hot press is performed while heating is performed, the highest temperature is 1550-1800 DEG C, and the hot press strength is 0.5-30 MPa. Under the condition of not adding a sintering agent, the high-purity compact calcium hexaluminate series refractory material is obtained by adopting a hot pressing sintering process according to the proportion, and the refractory material has excellent molten steel erosion resistance and thermal shock resistance and can be widely applied to industries such as metallurgy, building materials and petrochemical engineering. The preparation method is scientific and reasonable, the product purity is high, and the prepared refractory material product can prolong the equipment operation cycle, reduce the production cost and achieve the effects of energy conservation and emission reduction.
