Xa umntu esithi 'isiseko se-nickel', isiqingatha segumbi sicinga ngeenjini zejethi, esinye isiqingatha sicinga ngexabiso, imathiriyeli eyingxaki eyingxaki ngaphezu kokuba ifanelekile. Inyaniso, njengesiqhelo, ibambeke ndaweni ithile kumbindi ombi. Asiyobhulethi yomlingo, kodwa ukuyichitha nje 'njengexabiso elingabizi kakhulu' yindlela ekhawulezayo yokugqiba ngecandelo elingaphumeleliyo. Owona mngeni awukho nje ekuwucaciseni umzobo; kukwiwaka lezigqibo ezincinci ukusuka kwivenkile enyibilikayo ukuya kwipasile yokugqibela yomatshini.
Uluvo olungeyiyo olungundoqo: Konke malunga nobushushu
Uninzi lwamaphepha athile akhokelela ekusebenzeni kobushushu obuphezulu, kwaye akukho nto iphosakeleyo. Kodwa ukugxila kuphela kuloo 1200 ° F amandla okuqina kulapho iiprojekthi ziqala khona ukukhukuliseka. Ndibone uyilo olubethelwe kwi- isiseko se-nickel I-alloy efana ne-Inconel 718 ngenxa yokuba i-temp esebenzayo yayiphezulu, kuphela ukusilela kwi-chloride-induced stress corrosion cracking kumjikelo osezantsi wobushushu obungalindelekanga. I-alloy 'yayifaneleka ngokugqithisileyo' ubushushu kodwa yayingafanelanga ukuseyona ndawo ingqonge imichiza. Sifunda ntoni? Iprofayile ye-thermal sisahluko sokuqala nje. Udinga yonke i-corrosion kunye nebali lomatshini.
Ke kukho intsomi ye weldability. Buza umenzi wemveliso ukuba bayakwazi ukuyitshisa, baya kuthi ewe. Kodwa ngaba banokuyidibanisa kwaye babe nendawo echatshazelwe bubushushu igcine iipropathi ozenzileyo? Yincoko eyahlukileyo leyo. Unyango lwe-post-weld ubushushu kwezi alloys ayilocebiso; kudla ngokuba ngumahluko phakathi kwendibano yesandi kunye nokuqhekeka kwendawo elindele ukwenzeka. Sifunde oku ngendlela enzima kwiprojekthi ephindaphindiweyo kwiminyaka eyadlulayo, sicinga ukuba umgangatho we-PWHT womthengisi unokwanela. Ayizange ibe njalo. Umjikelo we-thermal uphelile, kwaye saphela nge-oxidation engaphambi kwexesha lokutya okuziinkozo.
Apha kulapho iqabane Foundry kunye namava machining iba non-negotiable. Ayikokuthenga i-casting; imalunga nokuthenga inkqubo elawulwayo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka kwiqokobhe kunye nokuphosa utyalo-mali, ufumana oku. Xa sele ugalela isiseko se-nickel ialloys ukuba ixesha elide, uye wakha ithala leembali thermal, uyilo gating, kunye neqhinga ukondla ezikhethekileyo kwezi mathiriyeli finicky. Ungazifumana apha https://www.tsingtaocnc.com. Ipotfoliyo yabo ayiloluhlu lwezinto nje kuphela; yirekhodi yeengxaki ezisonjululweyo kwi-cobalt kunye ne-nickel alloys.
Ukusuka Melt ukuya Machining: The Real cost Abaqhubi
Masithethe ngoomatshini, kuba kulapho uhlahlo lwabiwo-mali luthe cwaka. Abantu bajonga ixabiso lempahla ekrwada ngekhilogram kunye nokuphefumla. Emva koko bafumana isicatshulwa sokuqala somatshini kwaye bakhefuzele ngokwenene. Isiseko se-nickel ii-alloys ezifana ne-Hastelloy X okanye i-Waspaloy zisebenza nzima njengenye into. Isixhobo esibuthuntu okanye isantya sokutya esineentloni asikuthobi nje; idala ulusu oluqinileyo olwenza ukudlula okulandelayo kube nzima, okunokonakalisa inxalenye.
Ubuqhetseba bubundlongondlongo, obuvakala buphikisana. Udinga i-carbide ebukhali, i-premium-grade, ubulukhuni obuphezulu ekusetheni kwakho, kwaye kufuneka ungene phantsi komgangatho womsebenzi onzima ngexesha elinye. Ukukhanya, ukusika amanxeba lutshaba. Sakhe sazama ukonga kwisixhobo sebhetshi ye-Alloy 625 izibiyeli, sisebenzisa i-reground install. Ixesha lomjikelo liphindwe kabini, sitshise ngokuphindwe kathathu ukufakwa okuninzi, kwaye ukugqitywa komphezulu kwakungamkelekanga. 'Ukonga' kusidle kakhulu ngexesha lomatshini kunye nokusebenza kwakhona.
Yingakho iivenkile ezidibeneyo zinomphetho. Ukuba kwa eli qumrhu likhupha inxalenye likwayimatshini kwii-CNCs zabo, sele lisilungisile isibonelelo sokuqala sesitokhwe. Bayayazi imeko echanekileyo yomgangatho weendawo zabo zokuphosa. Akukho kwalatha ngomnwe phakathi kwe-Foundry kunye nevenkile yomatshini xa isixhobo siqhuma. Kwi-QSY, ukuphosa kwabo okudibeneyo kunye CNC Machining ukukwazi kuthetha ukuba bacinga ngokusikwa kokugqibela ngexesha lesigaba soyilo lokungunda. Olo lungelelwaniso luxabisekile ekulawuleni inxalenye yokugqibela yeendleko.
Ingxubevange Ngaphakathi kwengxubevange: Trace Elements Matter
Ukuchaza i-Inconel 718 sisiqalo nje. Ngaba yi-AMS 5662? I-AMS 5663 Umahluko kukuluhlu oluvumelekileyo lwe-aluminiyam, i-titanium, kunye ne-niobium. Ezo zishumi ezimbalwa zeepesenti ziyalela impendulo yokuguga kunye namandla okugqibela. Kwisicelo esiphezulu semfezeko, awuthengi igeneric 718; uthenga ikhemistri enyibilikayo ethile kunye nengxelo yonyango lobushushu eqinisekisiweyo.
Ndikhumbula enye indawo yomthengisi eyaphantse yabangela ukuvalwa. Inxalenye yaqinisekiswa njenge-718, kodwa yayikunyibilika kancinane kwe-spec elungiselelwe ukunyibilika, hayi ukuzinza kobushushu obuphezulu esibudingayo. Yadlula i-room-temp mechanicals, kodwa phantsi komthwalo kwi-1000 ° F, izinga lokunyuka lalingaphandle kwe-spec. Uhlalutyo lokungaphumeleli luyilandelele kwi-Al / Ti ratio. Ngoku, sihlala sicacisa eyona AMS okanye ikhowudi yokunyibilika yobunikazi kwaye ifuna iicerts zemill ezibonisa eyona chemistry, hayi nje ukuba 'ngaphakathi kwe-spec'.
Eli nqanaba lokulandelelwa lisisiseko sawo nawuphi na umboneleli onzulu. Licala elikruqulayo, elinzima lephepha lokusebenza nalo isiseko se-nickel i-alloys eyahlula amalungu asebenzayo kulawo angaphumeleli ngokuzolileyo. Inkqubo esemgangathweni ye-Foundry ayilophawu lolawulo; sisixhobo sokuvelisa.
Iza Kuyisebenzisa nini (Kwaye xa Uhamba nini)
Eyona ilungileyo isiseko se-nickel isicelo endakha ndasebenza kuso yayiseti yeethermowells zeyunithi ye-catalytic reformer. Imekobume yayiyihydrogen sulfide, ihydrogen yoxinzelelo oluphezulu, kunye neqondo lobushushu lebhayisikile ukuya kuma-950°F. Intsimbi engenastainless yayiza kugqwala okanye iqhume kwiinyanga. Amaqula angama-600 eInconel ahlala iminyaka. Iimeko zihambelana ngokugqibeleleyo nobuchule obuphambili be-alloy: i-corrosion enzima kunye ne-high temp.
Olona lubi kakhulu yayisisibiyeli solwakhiwo kwindawo engcolisekileyo, iqondo lobushushu elipholileyo. Umxhasi wayene-'nickel alloy' kumgangatho wabo weendawo ezibalulekileyo kwaye wala ukushukuma. Sasebenzisa i-Alloy 276. Yasebenza ngokungenasiphako, kodwa ixabiso lalingenangqondo. I-super duplex steel stainless ibiya kwenza umsebenzi kwisithathu sexabiso. Musa ukuvumela ingcaciso ethile ibe yinkolo. Vavanya eyona ndawo yenkonzo kuqala.
Esi sisigwebo esisebenzayo esiza ngokubona ezi nxalenye enkonzweni. Akukhona nje malunga nento enokuyenza i-alloy; imalunga nokuba amandla ayo awodwa ayimfuneko emsebenzini. Ngamanye amaxesha, eyona ntshukumo yengcali kukucebisa ngexabiso eliphantsi, imathiriyeli efanelekileyo.
Ikamva Ayiyonto Nje Ingxubevange Entsha
Kukho i-buzz eninzi malunga nomgubo omtsha we-metallurgy isiseko se-nickel ii-superalloys, kwaye ziyamangalisa. Kodwa kwizicelo ezininzi zemizi-mveliso, iinzuzo ezinkulu zikukuthembeka kwenkqubo kunye noyilo lokwenziwa kokwenziwa. Ngaba singakwazi ukuyila ijelo lokupholisa elintsonkothileyo libe yindawo yokuphosa ukunqanda indibano yebrazed? Ngaba singakwazi ukulungelelanisa i-radius ye-fillet ukuphelisa inyathelo lomatshini kunye nomxininiso woxinzelelo?
Intsebenziswano phakathi koyilo kunye nemveliso kufuneka iqine. Ukuthumela umzobo ogqityiweyo, ongenakwenzeka-ukuphosa kwisiseko kunye nokucela isicatshulwa sisiqalo esibi. Ukubandakanya iqabane lobuchwephesha elifana ne-QSY kwangethuba, xa uyilo lusemanzi, lubavumela ukuba bacebise uhlengahlengiso lwesandi kunye nobuchule. Amava abo ngaphaya intsimbi, intsimbi, kwaye ialloys ezikhethekileyo ibanika imbono ebanzi malunga nokuba yintoni ecela umngeni ngokukodwa malunga nomsebenzi wesiseko se-nickel.
Ekugqibeleni, ukusebenza ngempumelelo ngezi zixhobo kumalunga nokuhlonipha ukuntsonkotha kwazo ngaphandle kokoyika. Ngumxube wenzululwazi engqongqo-ukukhangela ezo ziqinisekiso zokusila, ukuqiniswa komfuziselo-kwaye phantse ubugcisa bomgangatho wevenkile uziva, njengokwazi isandi esichanekileyo ekufuneka sisenziwa sisixhobo xa sisika i-Inconel ekunene. Loo mxube yinto ejika into enzima ibe sisisombululo esithembekileyo.
