Izici ze-Inconel X-750
I-Inconel X-750 alloy ngokuyinhloko iyi-superalloy esekwe ku-nickel eqiniswa ngeminyaka ngesigaba esingu-γ[Ni3(Al, Ti, Nb)].Inokumelana nokugqwala okuhle nokumelana ne-oxidation ngaphansi kuka-980 ℃, futhi ngaphansi kuka-800 ℃ Inokumelana nokugqwala okuphezulu.Inokumelana okuhle nokuphumula okungaphansi kuka-540°C, kanye nokwakheka okuhle nokushisela.Le ngxubevange isetshenziselwa ikakhulukazi ukwakhiwa kwezinjini zezindiza ezisebenza ngaphansi kuka-800°C futhi ezidinga amandla aphezulu..Iziphethu zingasetshenziswa futhi ukwenza ama-steam turbine blades nezinye izingxenye, njengamapuleti, imicu, imigoqo, ama-forging, izindandatho, izintambo, amapayipi, njll.
I-Inconel X-750 Inqubo Yokwelapha Ukushisa
Isixazululo sesistimu yokwelapha ukushisa kwamapuleti, amapheshana kanye namapayipi esimweni sokuhlinzekwa ngu-980℃±15℃, ukupholisa komoya.Ngohlelo lokwelapha ukushisa okuphakathi kwezinto kanye nezingxenye, izinqubo ezilandelayo zingakhethwa ukwelashwa kokushisa.
I-Anealing: 955℃1010℃, ukupholisa amanzi.
Ukufakwa kwezingxenye ezishiselwe ngaphambi kokushisela: 980℃, 1h.
Ukunciphisa ingcindezi kwezingxenye ezishiselwe: 900℃, ukuswakama amahora angu-2.
Ukunciphisa ingcindezi: 885℃±15℃, 24h, ukupholisa komoya.
I-Inconel X-750 Izinhlobo Ezitholakalayo Nezicaciso
Amabha, ama-forging, amaringi, amashidi agoqelwe ashisayo, amashidi agoqwe abandayo, imicu, amashubhu nezintambo kungahlinzekwa ngosayizi abahlukahlukene.
Amapuleti namapheshana ngokuvamile ahlinzekwa ngemva kokugoqwa okushisayo noma okubandayo, ukugoqa noma isixazululo, ukucotshwa nokupholishwa.
Amabha, ama-forging kanye namasongo anganikezwa esimweni esigoqiwe noma esishisayo;zingabuye zinikezwe ekwelashweni kwesixazululo ngemuva kokubumba;imigoqo ingahlinzekwa ngemuva kwesixazululo futhi ipholishwe noma iguqulwe, futhi inganikezwa kubanda lapho i-oda lidinga isimo se-Pull endaweni.
Ucingo lunganikezwa esimweni sesixazululo esiqinile;ocingweni olunobubanzi obujwayelekile noma ukujiya obungaphansi kuka-6.35mm, lungaba yisixazululo esiqinile futhi lunikezwe ukuguqulwa komdwebo obandayo okungama-50% kuya ku-65%;ububanzi obujwayelekile noma ubude bohlangothi bukhulu kuno-6.35mm.I-wire, ngemva kokwelashwa kwesisombululo, ihlinzekwa nge-deformation yomdwebo obandayo ongekho ngaphansi kuka-30%.Ezintanjeni ezinobubanzi obujwayelekile noma ubude obuseceleni obungekho ngaphezu kuka-0.65mm, zingahlinzekwa ngokuguqulwa komdwebo obandayo ongekho ngaphansi kuka-15% ngemva kokwelashwa kwesixazululo njengoba kudingeka.
I-Inconel X-750 Izindawo Zokufaka Isicelo
Ingxubevange isetshenziselwa ikakhulukazi ukwakhiwa kweziphethu zamaqabunga neziphethu zamakhoyili ezinezidingo zamandla aphezulu kanye nokumelana nokuxegiselwa kwezinjini ezisebenza ngaphansi kuka-800°C.Ingasetshenziswa futhi ukwenza izingxenye ezifana nama-turbine blades.Izinhlobo ezitholakalayo yishidi, i-strip, ibha, i-forging, iringi, intambo kanye neshubhu.
