Paunonzwa 'Inconel 625 kuisa mari pakudyara', iyo pfungwa yekukurumidza kazhinji ndeyekureva kwayo-kupokana kwekupokana, simba rakakura, zvese izvo zvakanaka zvinhu. Asi iyo chaiyo nyaya inotanga kana iwe uchiedza kugadzira yakaoma, yakatetepa-yakakomberedzwa chikamu nayo. Mukaha uripo pakati peiyo alloy's datasheet uye iyo yekutanga pasi ndipo panowanikwa fungidziro zhinji.
Hunhu hweAlloy uye Dilemma yeWakisi Patani
Inconel 625 haisi imwe nickel-base superalloy yaunokanda mukuita. Yayo yakakwira nickel uye chromium yemukati, ine iyo molybdenum uye niobium inosimudzira, inoipa iyo ine mukurumbira kuita, asiwo hunhu muforoma. Chimhingamupinyi chekutanga hachisi kunyange simbi; ndiyo wakisi. Kune yakaoma aerospace kana marine fittings, iyo pateni inoda kuve yakakwana. Chero kukanganisa kudiki kunokwidziridzwa mushure mekuvaka goko uye nekupisa kwakanyanya. Ndakaona mapurojekiti akawandisa uko chikamu chekutanga jekiseni rewakisi chakamhanyiswa, zvichitungamira kukugadzirisa zvakare kunodhura gare gare. Kudzikama kwe dimensional ye wakisi patani ye 625 yakakosha pane, toti, 316 chikamu chisina tsvina.
Ipapo kunouya goko. Iwe haugone kushandisa chero ceramic. Iyo yekupisa yekuwedzera kusawirirana pakati peyakajairwa silica-yakavakirwa prime jasi uye Inconel 625 panguva yekudonha uye pre-kupisa kunogona kukonzera micro-kutsemuka, yekuvhura yakakwana yekupinza simbi. Isu takachinjira kune yakasanganiswa silica kana zircon-yakavakirwa primary slurry system, iyo inonzwika nyore, asi kufona mune viscosity uye kuomesa nguva yekunyorova kwedu apa yaive yemwedzi-yeedzo. Imwe shamwari yekugadzira, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore avo Investment casting uye shell mold work, yakadzokorora izvi. Vakataura kuti kune yavo nickel-based alloys portfolio, iyo shell kuumbwa kwe625 inowanzoda tweak kana ichienzaniswa neyavo cobalt-based runs, kunyanya kune zvikamu zvine kamwe kamwe chikamu shanduko.
Ndidzo idzi dzigadziriso dzisina kujeka dzinopatsanura chinoshandiswa kukanda kubva kune chakaraswa. Iyo pre-cast chikamu che625 inoda ruremekedzo rwezveruzivo rwunogumira pane obsessive. Hausi kungovaka chiumbwa; iwe uri engineering yekupisa uye makemikari interface.
Kudurura: Ipo Dzidziso Inosangana neCrucible
Kunyunguduka nekudira Inconel 625 ndipo panosangana nerabha mugwagwa. Iyo alloy maitiro ekuumba yechipiri nhanho kana tembiricha yekudira uye yekutonhodza mwero isiri mukuwirirana igomba rekare. Haisi yekurova °C chete. Iwe unofanirwa kufunga nezvekuti simbi inoyerera sei kuburikidza neaya matete zvikamu zveceramic shell. Kunyanya kutonhorera, uye unoisa panjodzi yekukanganisa kana kuvhara kutonhora; kupisa zvakanyanya, uye iwe unowedzera kuita negoko, zvingangokanganisa kunaka kwepasi.
Takadzidza izvi nenzira yakaoma pachirongwa chekutanga che turbine seal ring. Iyo geometry yaive neboka rakakora rematanho madiki ekutonhodza. Madiro mashoma ekutanga aitaridzika zvakanaka pakuona, asi kuongororwa kweradiographic kwakaratidza nzvimbo dziri kure dzekunyungudika kwekutanga uye micro-porosity pamatanho echiteshi. Nyaya yacho? Huremu hwekupisa hweceramic hwakatenderedza iwo akaomarara maficha aive achichinja iyo yenzvimbo yekusimbisa chimiro nenzira yedu yakajairwa paramita yaisazvidavirira. Kugadzirisa kwaisanganisira kwete kungogadzirisa kupisa kwakanyanya, asi zvakare kugadzirisa gating system kuti ikurudzire kusimba kwakasimba kune inosimuka, musimboti wakakoshera wakarebeswa mukutsvaga kwekuwedzera goho.
Degassing chimwe chinhu chinyararire. Hydrogen pickup inogona kuva inotyisa. A rigorous degassing practice mu induction furnace is not-negotiable. Ini ndinorangarira batch apo ma mechanic zvivakwa, kunyanya kukanganisa kuoma, zvaisaenderana pazasi spec. Mushure mekutonga kunze chemistry, muparidzi akazove misiyano midiki yekunyorova mumhepo yemuchitoro inokanganisa kunyungudika. Chiyeuchidzo chinozvininipisa kuti nezvinhu zvakaita seizvi, nharaunda pachayo inova shanduko yemaitiro.
Post-Cast Reality: Kupisa Kurapa uye Machining Grind
As-cast Inconel 625 ine cored dendritic chimiro chinoda kuve homogenized. Iyo yakajairwa mhinduro inotenderedza kutenderera 1150 ° C inoteverwa nekudzima nekukurumidza ibhuku rekuverenga. Asi chikamu che 'kukurumidza kudzima' chine hunyengeri kune zvinorema-chikamu castings. Kana iwe ukasawana mwero wekudzima zvakanaka, unogona kupedzisira wanyanya kunaya kwecarbide pamiganhu yezviyo, iyo inozova nzvimbo yekutanga yekuora kana kutsemuka mubasa. Iyo chiyero pakati pekuwana iyo inodiwa kuparadzwa kwechikamu chechipiri uye kudzivirira kukanganisa kana kudzima kutsemuka.
Zvino kunouya CNC machining. Chero ani anofunga machining cast 625 akafanana nemachining bar stock ari mukuvhunduka. Iyo yakakandwa pamusoro pe layer, kazhinji ine kuomarara kwakasiyana zvishoma uye inogoneka alpha-chromium precipitates, inogona kutamba nyonganyonga nemacheto emidziyo. Takatora nzira inochengetedza, yakakwira-kudzvanya inotonhorera neyakaomarara maturusi nzira, tichibata ekutanga roughing inopfuura senge oparesheni yakaparadzana. Makambani anobatanidza kukanda uye machining, senge QSY (unogona kuona maitiro avo pa https://www.tsingtaocnc.com), ita zvakanaka pano. Machinist avo vanojairana neiyo chaiyo 'se-cast' mamiriro eiyo yavo yekutanga's 625 kuburitsa, iyo inobvumira mamwe akakwenenzverwa mafidhi uye kumhanya kubva pakuenda, kuderedza maturusi ekupfeka uye kugadzirisa kwekupedzisira kwepamusoro pekupedzisira pazviso zvakakosha zvekuisa chisimbiso.
Mutengo wechikamu chakaraswa mushure memaawa ekugadzira wakakura kwazvo kupfuura yakaraswa mushure mekukanda. Iyi post-cast phase inowanzo tarisa iyo yakazara purojekiti kushanda.
Nyaya Yenyaya: Imba Yevhavha uye Dimensional War
Muenzaniso wekongiri yaive hombe, yakaoma valve imba yebasa rekunze kwemahombekombe. Kudhinda kwacho kwakadaidza ASME SB-366 Giredhi CW6MC (iyo yekukanda yakaenzana neInconel 625) ine yakazara NACE MR0175 kuteedzera kwesevhisi inovava. Dambudziko rakanga risiri bvunzo dzekuora; yakanga yakabata 0.2mm kushivirira pane yakakura, isina kujairika yemukati bhora mushure mekupisa.
Kukandira uye kupisa kupisa kwakakonzera kufanofungidzira asi kusiri-uniform dimensional shanduko. Nzira yedu yekutanga yekuwedzera generic machining stock allowance yakundikana. Isu taifanira kuita 'yekutanga chinyorwa' maitiro: kukanda, kupisa kupisa, ipapo 3D scan. Iyo scan data yakashandiswa kugadzira yakabhadharwa CNC chirongwa chekupedzisira machining. Yakawedzera nhanho, asi ndiyo chete nzira yekurova iyo spec nekuvimbika. Rudzi urwu rwekugadzirisa maitiro ekuyerera kwakakosha kune yakakwirira-kukosha Inconel 625 kuisa mari.
Inotaridzawo kuti nei kubatana kwepedyo pakati peiyo foundry uye shopu yemuchina kwakakosha. Pavanenge vari pasi pemba imwe chete, kana kuti vane mubatanidzwa wakasimba, zvishwe zvemhinduro zvipfupi. Nyaya dzakaita senge yasara yekushushikana maitiro kubva mukukanda iyo inoratidzwa panguva yekugadzira inogona kuongororwa uye kugadziriswa padanho rekugadzira danho rekumhanya kunotevera.
Kutarisa Kumashure Nekufambira Mberi
Saka, chii chekutora? Kubudirira Investment casting yeInconel 625 idambudziko reinjiniya masisitimu. Haisi nzira yezvigadzirwa. Zvinoda kunzwisisa kwakadzama, kunenge kunzwisisika kwekuti nhanho imwe neimwe-kubva pawakisi kusvika pakuongorora kwekupedzisira-inopesvedzera sei inotevera. Iyo alloy hairegereri mapfupi.
Iyo indasitiri iri kufamba ichienda kune imwe simulation, iyo inobatsira. Modeling solidification uye kushushikana kunogona mureza zvinogona kupisa nzvimbo. Asi kuenzanisa kwacho kwakangonaka senge data yemidziyo uye mamiriro emuganho aunoidyisa, ayo achiri anowanzo kubva muyedzo yechinyakare uye kukanganisa.
Kune mainjiniya ari kutsvaga zvikamu izvi, kiyi ndeyekutarisa kupfuura bhurocha rekutengesa. Bvunza nezve masheti emateko akashandiswa pa625. Kurukurai data ravo renhoroondo pamusoro pedimensional repeatability post-heat-treat yemajiometri akafanana. Bvunza nezve yavo-mumba machining kugona kwezvinhu. Inyanzvi yemutengesi se QSY, nekutarisa kwayo kwenguva refu pane yakakosha alloys uye yakabatanidzwa CNC machining, kazhinji iri muruzivo urwu rwakaunganidzwa, runoshanda-rudzi runoshandura dhizaini yakaoma kuita chinhu chakavimbika, chinoshanda. Ndiko kukosha chaiko mumunda uyu.
