Description

technical field [0001] The invention relates to the technical field of alloy melting and casting, in particular to an integrated device and method for melting and casting of iron-chromium-aluminum alloys. Background technique [0002] Fe-Cr-Al superalloy has relatively low thermal expansion coefficient, strong high-temperature oxidation resistance, and relatively low production cost. Considering comprehensive considerations such as processing performance and economic value, it is the best material for the carrier of internal combustion engine exhaust gas purifier. At present, the typical composition of superalloys for metal carriers of internal combustion engine exhaust purifiers at home and abroad is C≤0.05%, Si≤0.40%, Al: 3.50~6.00%, Cr: 17.0~20.0%, RE: 0.02~0.12%, and the balance is Fe . [0003] However, due to the high Al content in the alloy and the application of rare earths, Fe-Cr-Al alloys are easily oxidized during the casting process, resulting in nodules at the ...
