| titleOfInvention | A kind of Al2OC-AlN solid solution combined corundum refractory for blast furnace ceramic cup and preparation method |
| abstract | An Al 2 OC-AlN solid solution combined corundum refractory material for a blast furnace ceramic cup and a preparation method thereof belong to the field of refractory materials. The raw material composition is 57% corundum particles with a particle size of 1-3mm, 13% corundum particles with a particle size of 550-600μm, 6-26% corundum fine powder with a particle size of 38-45μm, 3-18% metal with a particle size of 38-45μm Aluminum powder, 1-6% silicon nitride powder with a particle size of 38-45 μm, plus 2-6% of the total weight of the above raw materials, a binder phenolic resin, and the metal aluminum content is 3 times the silicon nitride content. During preparation, various raw materials are weighed according to the formula, mixed evenly and kneaded to obtain mud, which is then pressed into shape, first dried at 200 ° C for more than 12 hours, and then heated to 550-650 ° C under nitrogen atmosphere for 6-10 hours, and then Sinter at 1500‑1700℃ for 3‑6h. The obtained product has an apparent porosity of 9-14%, a bulk density of 2.90-3.10 g/cm 3 , and a compressive strength at room temperature of 260-340 MPa. The method has high chemical stability of raw materials, does not contain carbon and easily hydratable AlN and Al 4 C 3 , and has low equipment requirements. The Al 2 OC-AlN solid solution combined corundum refractory material is successfully prepared, which can be produced on a large scale. |
