Iyo wunvise 'Inconel 625 ishoramari', igitekerezo cyahise kijyanye nibisobanuro byayo - kurwanya ruswa, imbaraga nyinshi, nibintu byiza byose. Ariko inkuru nyayo itangira iyo ugerageje gukora mubyukuri ibintu bigoye, bikikijwe nurukuta. Ikinyuranyo hagati ya datasheet ya alloy na etage ya fondasiyo niho ibitekerezo byinshi binanirwa.
Imiterere ya Alloy hamwe na Wax Pattern Dilemma
Inconel 625 ntabwo arikindi nikel-base superalloy uta mubikorwa. Nikel nyinshi hamwe na chromium yibirimo, hamwe na molybdenum na niobium byongera imbaraga, biha iyo mikorere yimigani, ariko kandi numuntu muburyo. Inzitizi ya mbere ntabwo ari icyuma; ni ibishashara. Ku kirere gikomeye cyangwa mu nyanja, icyitegererezo kigomba kuba cyuzuye. Inenge iyo ari yo yose iba minini nyuma yo kubaka igikonje n'ubushyuhe bukabije. Nabonye imishinga myinshi aho icyiciro cya mbere cyo gutera ibishashara cyihuta, biganisha ku gukora bihenze nyuma. Ihagarikwa ryimiterere yibishashara kuri 625 irakomeye kuruta kuri, tuvuge, igice 316 kitagira umwanda.
Hanyuma haza igikonoshwa. Ntushobora gukoresha ububumbyi ubwo aribwo bwose. Kwiyongera k'ubushyuhe budahuye hagati ya silika isanzwe ishingiye kuri silika na Inconel 625 mugihe cyo kwangiza no kubushyuhe burashobora gutera micro-gucika, icyuma cyiza cyo kwinjira mubyuma. Twimukiye kuri silika yahujwe cyangwa sisitemu ya primaire ya zircon, isa nkiyoroshye, ariko guhamagara mugihe cyizuba nigihe cyo kumisha kubushuhe bwacu hano byari ikigeragezo cyamezi. Umufatanyabikorwa, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu muri gushora imari Igikonoshwa cyibikorwa, byagarutsweho ibi. Bagaragaje ko kubijyanye na nikel ishingiye kuri alloys portfolio, igishishwa cya 625 gikenera guhinduka ugereranije nibikorwa byabo bishingiye kuri cobalt, cyane cyane kubice bifite impinduka zitunguranye.
Nibintu byoroshye byahinduwe bitandukanya gukina gukoreshwa nibisigazwa. Icyiciro cyabanjirije icyiciro cya 625 gisaba kubaha ibisobanuro birambuye bihana imbibi. Ntabwo wubaka gusa; urimo gukora injeniyeri yubushyuhe nubumashini.
Isuka: Aho Igitekerezo gihurira na Crucible
Gushonga no gusuka Inconel 625 niho reberi ihurira n'umuhanda. Amavuta ya alloy yo gukora icyiciro cya kabiri niba isuka ya temp hamwe nigipimo cyo gukonjesha bitari murwego rumwe ni umutego wa kera. Ntabwo ari ugukubita ° C. Ugomba gusuzuma uburyo ibyuma bitembera muri ibyo bice bito bya ceramic shell. Birakonje cyane, kandi ushobora guhura nabi cyangwa gufunga imbeho; birashyushye cyane, kandi wongera reaction hamwe nigikonoshwa, birashobora kugira ingaruka kubusugire.
Ibi twabyize inzira igoye kumushinga hakiri kare impeta ya kashe ya turbine. Geometrie yari ifite ihuriro ryinshi ryimiyoboro ikonje. Amasuka ya mbere yasaga neza neza, ariko ibizamini bya radiografi byagaragaje uduce twitaruye two gushonga bidahwitse hamwe na micro-porosity ku masangano y'umuyoboro. Ikibazo? Ubushuhe bwubushyuhe bwa ceramic hafi yibyo bintu bigoye byahinduye umwirondoro wibanze muburyo ibipimo bisanzwe bitabazwe. Gukosora ntabwo byari uguhindura ubushyuhe bukabije gusa, ahubwo byanashushanyijeho uburyo bwo kwinjiza amarembo kugirango habeho gushimangira icyerekezo cyerekeza kuri risers, ihame ryibanze ryirengagijwe mugushakisha umusaruro mwinshi.
Gutesha agaciro ni ikindi kintu cyicecekeye. Imodoka ya hydrogen irashobora kuba inzozi mbi. Imyitozo ikaze itesha agaciro mu itanura rya induction ntabwo iganirwaho. Ndibuka icyiciro aho imiterere yubukanishi, cyane cyane ingaruka zikomeye, zari zidahuye munsi ya spec. Nyuma yo kwanga chimie, nyirabayazana yaje kuba itandukaniro rito ry'ubushyuhe mu kirere cy’amaduka bigira ingaruka ku gushonga. Nukwicisha bugufi kwibutsa ko hamwe nibikoresho nkibi, ibidukikije ubwabyo bihinduka inzira ihinduka.
Inyuma ya nyuma yukuri: Kuvura ubushyuhe no gusya imashini
As-cast Inconel 625 ifite imiterere ya dendritic ikeneye guhuzwa. Igisubizo gisanzwe gifata hafi 1150 ° C gikurikirwa no kuzimya vuba ni igitabo. Ariko igice cyihuta 'kuzimya' kiragoye kubice-biremereye. Niba utabonye igipimo cyo kuzimya neza, urashobora kurangiza kugwa kwa karbide ikabije kumupaka wingano, hanyuma bigahinduka intangiriro yo kwangirika cyangwa guturika muri serivisi. Nuburinganire hagati yo kugera ku iseswa risabwa ryicyiciro cya kabiri no kwirinda kugoreka cyangwa kuzimya.
Hanyuma haza Imashini ya CNC. Umuntu wese utekereza gutunganya imashini 625 asa nogukora ibigega byabigenewe arimo gutungurwa. Igice cyo hejuru cyubutaka, akenshi hamwe nubukomere butandukanye gato kandi imvura ya alfa-chromium ishobora kugwa, irashobora gukinisha ibintu hamwe nibikoresho. Twafashe ingamba zo gukumira, umuvuduko ukabije wo gukonjesha hamwe n'inzira zikomeye zikoreshwa, dufata inzira ya mbere itoroshye nko gukora bitandukanye. Ibigo bihuza casting na mashini, nka QSY (urashobora kubona uburyo bwabo kuri https://www.tsingtaocnc.com), gira akarusho hano. Abakanishi babo bamenyereye imiterere yihariye ya 'as-cast' yimishinga yabo 625 isohoka, itanga uburyo bwiza bwo kugaburira no kwihuta kuva aho bigeze, kugabanya kwambara ibikoresho no kunoza ubuso bwanyuma kumaso akomeye.
Igiciro cyaciwe nyuma yamasaha yo gutunganya kirarenze kure kimwe cyakuweho nyuma yo guta. Icyiciro cya nyuma yicyiciro kigena muri rusange umushinga ushobora kubaho.
Ikiburanwa: Amazu ya Valve nintambara ya Dimensional
Urugero rufatika ni inzu nini, igoye ya valve ya serivisi yo hanze. Icapiro ryasabye ASME SB-366 Icyiciro CW6MC (casting ihwanye na Inconel 625) hamwe na NACE MR0175 yuzuye kugirango serivisi zisharira. Ikibazo ntabwo cyari ikizamini cya ruswa; yari ifite kwihanganira 0.2mm kumurongo munini, udasanzwe nyuma yo kuvura ubushyuhe.
Gutera no gushyushya ubushyuhe byateje guhinduka ariko bidahuje ibipimo. Uburyo bwacu bwambere bwo kongeramo amafaranga yimashini yibikoresho byananiranye. Tugomba gushyira mubikorwa 'ingingo yambere': gukina, kuvura ubushyuhe, hanyuma 3D scan. Gusikana amakuru yakoreshejwe mugukora progaramu ya CNC yishyuwe kumashini yanyuma. Yongeyeho intambwe, ariko niyo nzira yonyine yo gukubita spec yizewe. Ubu bwoko bwo guhuza n'imihindagurikire y'ikirere ni ingenzi cyane Inconel 625 gushora imari.
Irerekana kandi impamvu ubufatanye bwa hafi hagati yimishinga nububiko bwimashini ari ngombwa. Iyo bari munsi yinzu, cyangwa bafite ubufatanye bukomeye, ibitekerezo bisubirwamo ni bigufi. Ibibazo nkibisigisigi byuburyo buturuka kumukino ugaragara mugihe cyo gutunganya birashobora gusuzumwa no gukemurwa murwego rwo gushushanya icyiciro gikurikira.
Kureba Inyuma no Kujya Imbere
None, ni ubuhe buryo bwo gufata? Intsinzi gushora imari ya Inconel 625 nikibazo cya sisitemu yubuhanga. Ntabwo ari inzira y'ibicuruzwa. Irasaba gusobanukirwa byimbitse, hafi yukuntu buri ntambwe - kuva ibishashara kugeza ubugenzuzi bwa nyuma - bigira ingaruka kubikurikira. Amavuta ntababarira shortcuts.
Inganda zigenda zigana byinshi byigana, bifasha. Kwerekana gukomera no guhangayika birashobora kwerekana ibibanza bishobora gushyuha. Ariko kwigana nibyiza gusa nkibintu byumutungo wibintu hamwe nimbibi urigaburira, biracyaturuka kubigeragezo bishaje no kwibeshya.
Kuri ba injeniyeri bashakisha ibi bice, urufunguzo ni ukureba ibirenze kugurisha. Baza ibijyanye na sisitemu yihariye ikoreshwa kuri 625. Muganire ku mateka yabo ku mateka yisubiramo nyuma yubushyuhe-bwo kuvura geometrike isa. Baza ibijyanye n'ubushobozi bwabo bwo gutunganya ibikoresho. Ubuhanga bwabatanga nka QSY, hamwe nigihe kirekire cyibanda kumyanya idasanzwe kandi ihuriweho Imashini ya CNC, akenshi biri muri ubu bumenyi bwegeranijwe, bufatika-ubwoko buhindura ibintu bitoroshye bivanze muburyo bwizewe, bukora. Ngiyo agaciro nyako muriki gice.
