| titleOfInvention | Composite multilayer crucible for beryllium-aluminum alloy induction smelting and preparation method thereof |
| abstract | The invention discloses a composite multilayer crucible for beryllium-aluminum alloy induction melting and a preparation method thereof, and solves the problem that no crucible suitable for beryllium-aluminum alloy induction melting exists in the prior art. The composite multilayer crucible comprises an inner layer crucible, a middle layer crucible and an outer layer crucible which are fixedly connected in sequence from inside to outside; the inner-layer crucible is made of 92.5-97.5 parts of beryllium oxide, 1.0-2.0 parts of calcium oxide, 0.5-2.0 parts of yttrium oxide and 1.0-3.5 parts of silicon carbide; the middle layer crucible is made of graphite; the outer crucible is made of 90-95 parts of calcium oxide, 1-3 parts of magnesium oxide, 2-4 parts of yttrium oxide, 1-1.5 parts of zirconium oxide and 0.5-1.5 parts of clay. The composite multilayer crucible structure has higher structural strength and can shield a considerable part of induction magnetic field. The chemical property is stable, the melt does not splash in the smelting process, the oxygenation degree is low, part of single-layer structures can be replaced and reused, and the service life is long. |
