Xa usiva 'i-Inconel 625 yotyalo-mali olulahlwayo', ingcinga ekhawulezileyo ihlala imalunga ne-spec-ukumelana nokubola, ukomelela okuphezulu, zonke ezo zinto zilungileyo. Kodwa ibali lokwenyani liqala xa uzama ukwenza into entsonkothileyo, enodonga olucekethekileyo ngayo. Umsantsa phakathi kwedatha yealloyi kunye nomgangatho wesiseko kulapho uninzi lweengqikelelo zisilela khona.
Ubume beAlloy kunye neNgxaki yePatheni yeWax
I-Inconel 625 ayisiyonto nje enye i-nickel-base superalloy oyiphosayo kwinkqubo. I-nickel ephezulu kunye nomxholo we-chromium, kunye ne-molybdenum kunye ne-niobium boost, inika ukusebenza okuqhelekileyo, kodwa kunye nobuntu ekubunjeni. Umqobo wokuqala awuyontsimbi; yiwax. Kwi-aerospace eyinkimbinkimbi okanye izixhobo zaselwandle, ipateni kufuneka iphelele. Nasiphi na isiphene esincinci siba sikhulu emva kokwakhiwa kweqokobhe kunye nobushushu obugqithisileyo. Ndibone iiprojekthi ezininzi kakhulu apho isigaba sokuqala sokutofa i-wax sakhawuleziswa, sikhokelela ekusebenzeni kwakhona okunexabiso elikhulu kamva. Uzinzo lwe-dimensional yepateni ye-wax ye-625 ibaluleke kakhulu kunokuba, yithi, inxalenye ye-316 engenasici.
Emva koko kuza iqokobhe. Awukwazi ukusebenzisa nayiphi na i-ceramic. Ukungahambelani kokwandiswa kwe-thermal phakathi kwe-silica-based prime coat kunye ne-Inconel 625 ngexesha le-dewaxing kunye nobushushu bangaphambili kunokubangela ukuqhekeka kwe-micro, i-launchpad efanelekileyo yokungena kwesinyithi. Sitshintshele kwi-silica edityanisiweyo okanye i-zircon-based based slurry system, evakala ilula, kodwa ukudayela kwi-viscosity kunye nexesha lokumisa lokufuma kwethu apha yayilulingo olude lweenyanga. Isiseko seqabane, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye namashumi amathathu eminyaka abo utyalo mali kunye nomsebenzi wokungunda weqokobhe, ubethelele oku. Baye babonisa ukuba iphothifoliyo ye-alloys esekelwe kwi-nickel, ukuqulunqwa kwegobolondo ye-625 kaninzi idinga i-tweak xa kuthelekiswa nokugijima kwabo okusekelwe kwi-cobalt, ngokukodwa kwiindawo ezinokuguqulwa kwecandelo ngokukhawuleza.
Ngolu lungelelwaniso lufihlakeleyo olwahlula isakhelo esisebenzisekayo kwisilahlwa. Inqanaba lokuphoswa kwangaphambili le-625 lifuna ukuhlonitshwa kweenkcukacha ezinqamle kwi-obsessive. Anisakhi nje ukubumba; uyinjineli yojongano olushushu kunye nekhemikhali.
Ukugalela: Apho ithiyori idibana neCrucible
Ukunyibilika kunye nokuthulula i-Inconel 625 kulapho irabha idibana khona nendlela. Utyekelo lwealloyi ekwenzeni izigaba zesibini ukuba iqondo lokugalela kunye nesantya sokupholisa azikho sync ngumgibe oqhelekileyo. Akunjalo nje malunga nokubetha i-°C. Kuya kufuneka uqwalasele indlela isinyithi ehamba ngayo kula macandelo amancinci eqokobhe leceramic. Ipholile kakhulu, kwaye ubeka umngcipheko wokungahambi kakuhle okanye ukuvalwa okubandayo; kushushu kakhulu, kwaye wenza mandundu ukusabela ngeqokobhe, okunokuchaphazela ingqibelelo yomphezulu.
Oku sikufunde kabuhlungu kwiprojekthi yokuqala yeringi yokutywina yeinjini yomoya. Ijometri yayineqela elishinyeneyo lamatshaneli amancinci okupholisa. Ukugalela okumbalwa kokuqala kujongeka kukuhle ngokubonakalayo, kodwa uvavanyo lweradiyographic luveze iindawo ezikwanti zokunyibilika kwe-incipient kunye ne-micro-porosity kwiindibano zesiteshi. Ingxaki? Ubunzima be-thermal ye-ceramic ejikeleze ezo mpawu zintsonkothileyo zaziguqula iprofayile yoqiniswa yasekhaya ngendlela iparameters zethu ezisemgangathweni ezingakhange ziphendule ngayo. Ulungiso alubandakanyi nje ukulungelelanisa ukushisa okuphezulu, kodwa kunye nokuyila ngokutsha inkqubo yokungena ukukhuthaza ukuqina okuthe chatha kwicala lokunyuka, umgaqo osisiseko owathi watyeshelwa kumzamo wokwandisa isivuno.
I-Degassing yenye into engathethiyo. Ukuthatha i-hydrogen kunokuba liphupha elibi. Isenzo esingqongqo sokususa igassing kwisithando somlilo sokungeniswa asikwazi kuthethathethwana. Ndikhumbula ibhetshi apho iipropathi zoomatshini, ngakumbi ukuqina kwempembelelo, bezingahambelani ngezantsi kwe-spec. Emva kokulawula ikhemistri, umenzi wobubi uye wajika waba kukwahluka kokufuma okuncinci kumoya wevenkile ochaphazela ukunyibilika. Sisikhumbuzo esithobekileyo sokuba ngemathiriyeli efana nale, imo engqongileyo ngokwayo iba yinkqubo eguquguqukayo.
Inyani ye-Post-Cast: Unyango lobushushu kunye ne-Machining Grind
I-As-cast Inconel 625 inesakhiwo se-dendritic esine-cored esifuna ukuba i-homogenized. Isisombululo esisemgangathweni esijikeleze i-1150 ° C silandelwa kukucinywa ngokukhawuleza yincwadi yokufunda. Kodwa icandelo 'lokucima ngokukhawuleza' liyakhohlisa kwi-heavy-section castings. Ukuba awulifumani inqanaba lokucima ngokufanelekileyo, ungaphela sele unemvula egqithisileyo ye-carbide kwimida yeenkozo, ethi ibe sisiqalo somhlwa okanye ukuqhekeka kwinkonzo. Lulungelelwano phakathi kokuphumeza ukupheliswa okufunekayo kwezigaba zesibini kunye nokuphepha ukugqwetheka okanye ukucima ukuqhekeka.
Emva koko kuza CNC Machining. Nabani na ocinga ukuba i-machining cast 625 ifana ne-machining bar stock ukothuka. Umaleko womphezulu otyhidiweyo, uhlala unobulukhuni obahluke kancinane kunye ne-alpha-chromium precipitates enokwenzeka, unokudlala inkathazo ngemiphetho yesixhobo. Siye samkela indlela yogcino, yoxinzelelo oluphezulu yokupholisa ngeendlela eziqinileyo zesixhobo, siphatha iipasi zokuqala ezirhabaxa phantse njengomsebenzi owahlukileyo. Iinkampani ezidibanisa ukuphosa kunye nomatshini, njenge QSY (Ungayibona indlela yabo apha https://www.tsingtaocnc.com), yiba neadvanteji apha. Oomatshini babo baqhelene nemeko ethile 'njenge-cast' yemveliso yabo ye-625, evumela ukondla okulungiselelwe ngakumbi kunye nezantya ukusuka ekuqaleni, ukunciphisa ukunxitywa kwesixhobo kunye nokuphucula ukugqitywa komgangatho wokugqibela kubuso obubalulekileyo bokutywinwa.
Iindleko zenxalenye echithiweyo emva kweeyure zomsebenzi zikhulu kakhulu kunomnye olahliweyo emva kokuphosa. Esi sigaba sasemva kokuphoswa sihlala simisela ukwenzeka kweprojekthi iyonke.
Inqaku leMyelelo: Izindlu zeValve kunye neMfazwe yoMda
Umzekelo obambekayo yayiyindlu enkulu, entsonkothileyo yevalvu yenkonzo ye-offshore. Ushicilelo lubize i-ASME SB-366 Grade CW6MC (i-casting elingana ne-Inconel 625) ngokuthotyelwa kwe-NACE MR0175 ngokupheleleyo ngenkonzo emuncu. Ucelomngeni yayingelovavanyo lomhlwa; yayibambe i-0.2mm yokunyamezela kwi-bore yangaphakathi enkulu, engaqhelekanga emva konyango lobushushu.
Ukugalelwa kunye nokuphathwa kobushushu kubangele utshintsho oluqikelelwayo kodwa olungelulo ufanayo. Indlela yethu yokuqala yokongeza isibonelelo somatshini wegeneric asiphumelelanga. Kuye kwafuneka siphumeze inkqubo 'yenqaku lokuqala': ukuphosa, ukunyanga ubushushu, emva koko ukuskena kwe-3D. Idatha yokuskena isetyenziselwe ukwenza inkqubo ye-CNC ehlawulwayo ukwenzela umatshini wokugqibela. Yongeza inyathelo, kodwa yayikuphela kwendlela yokubetha i-spec ngokuthembekileyo. Olu hlobo lokuhamba kwenkqubo yokulungelelanisa lubalulekile kwixabiso eliphezulu Inconel 625 utyalo mali.
Ikwaqaqambisa ukuba kutheni intsebenziswano esondeleyo phakathi kwe-Foundry kunye nevenkile yoomatshini ibalulekile. Xa bephantsi kophahla olunye, okanye banentsebenziswano eqinileyo, iilophu zempendulo ziba mfutshane. Imiba efana neepateni zoxinzelelo olushiyekileyo oluvela ekusalweni olubonakala ngexesha lomatshini inokufunyaniswa kwaye iqwalaselwe kwinqanaba loyilo lwenkqubo yokubaleka okulandelayo.
Ukujonga Ngasemva kwaye Ukuqhubela Phambili
Ngoko ke, yintoni i-takeway? Iphumelele utyalo mali ye-Inconel 625 yingxaki yobunjineli beenkqubo. Asiyonkqubo yorhwebo. Ifuna ukuqonda okunzulu, phantse okucacileyo malunga nokuba inyathelo ngalinye-ukusuka kwi-wax ukuya ekuhlolweni kokugqibela-lichaphazela njani elilandelayo. Ingxubevange ayizixoleli iindlela ezimfutshane.
Ishishini liqhubela phambili ekufaniseni ngakumbi, okuncedayo. Ukulinganisa ukuqina kunye noxinzelelo kunokufaka iflegi yeendawo ezishushu ezinokubakho. Kodwa ukulinganisa kulungile kuphela njengedatha yepropathi yezinto kunye neemeko zomda oyazondla ngazo, ezihlala zivela kulingo lwakudala kunye nempazamo.
Kwiinjineli ezikhangela la malungu, undoqo kukujonga ngaphaya kwencwadana yokuthengisa. Buza malunga neenkqubo ezithile zeqokobhe ezisetyenziselwa u-625. Buza malunga nobuchule babo bokwenza umsebenzi wangaphakathi wezinto eziphathekayo. Ubungcali bomthengisi onje QSY, kunye nokugxila kwexesha elide kwii-alloys ezikhethekileyo kunye nokudibanisa CNC Machining, ngokuqhelekileyo kulele kolu lwazi luqokelelweyo, olusebenzayo-uhlobo olujika i-alloy specifikationer enzima ibe yinto ethembekileyo, esebenzayo. Elona xabiso lokwenyani kule ndawo.
