| Abstract: |
| The anode copper casting mold repairing material was prepared by using waste magnesia chrome brick, alumina, silicon carbide and dihydrogen aluminum phosphate as raw materials. The mechanical properties and microscopic analysis of the anode copper casting mold repairing material were analyzed by mechanical testing machine, SEM, TG-DTG and XRD. Morphology, heat resistance and crystal form change. The results show that the surface morphology of the anode copper casting mold repairing material is better than that of 30% magnesia chrome brick, 30% alumina, 40% silicon carbide, and aluminum dihydrogen phosphate with a liquid-solid ratio of 0.6:1. There is no obvious bubble generation, the compressive strength is 7.62MP, the tensile strength is 0.403MP, there is no crystal water after 140°C, and the die life is increased by 39.89%. |
