Iyo ba injeniyeri bagaragaje Inconel 718, ntabwo bahitamo gusa ibikoresho-biyemeje gutuza kurwego rwa 650 ° C, kurwanya ihungabana-ruswa ryangirika mubidukikije bya gaze, hamwe nubuzima bwumunaniro munsi yubushyuhe bwumuriro. Ariko ibikoresho fatizo bisobanuye bike udafite umufatanyabikorwa uzi imyitwarire mu iduka. Aho niho an Uruganda rwa Inconel 718 yinjiza uburemere bwayo - ntabwo ari mu gatabo, ahubwo isubirwamo mu bice 200, mu kubahiriza GD&T ku bijyanye no kwihanganira 0.005-mm, no gutungurwa na zeru mu gihe cyo kugenzura ingingo ya mbere.
Kuki "Uruganda" rufite agaciro kuruta "Utanga" kuri Inconel 718
Twabonye imishinga myinshi ihagaze kubera ko isosiyete yubucuruzi yakuye ububiko bwa Inconel 718 mu ruganda rumwe, ikavura ubushyuhe ku itanura ry’abandi bantu, hanyuma ikohereza mu iduka rya CNC ridafite ubugenzuzi bw’ibyuma. Igisubizo? Microstructure variable hagati yubushyuhe. Ubuso bwa decarburisation kuri flanges zahindutse. Urupapuro rusigaye ruterwa nintambara nyuma yo gutunganywa bwa nyuma - byagaragaye gusa mugihe cyo gupima hydraulic. Nukuri Uruganda rwa Inconel 718 Afite urunigi: ibyemezo byibanze byemewe, murugo igisubizo annealing hamwe nubusaza, hamwe nibikoresho byo gutunganya byemewe kuri Inconel 718 nyirizina - ntabwo ari nikel-alloy presets.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri kintu cyose cya Inconel 718 gitangirana na fagitire yemewe na AMS 5662, igenzurwa binyuze muri PMI na OES mbere yo kwinjira mu bicuruzwa. Ntabwo dushyira hanze kuvura ubushyuhe. Itanura ryacu rya vacuum rikurikiza neza AMS 2750E ya pyrometer ya kalibrasi ya kalibrasi - kandi tugumana amateka yuzuye yubushyuhe kuri buri kintu. Ibi ntabwo biri hejuru. Nuburyo dufata ± 0.01 mm kuri 320-mm-ya diametre ya piston pompe ya silinderi mugihe dukomeza Ra 0.4 µm kurangiza kubutaka bwimbere.
Aho Imashini zisanzwe zananiranye-kandi niki gikora
Amaduka amwe afata Inconel 718 nkicyuma gikomeye. Ntabwo babikora. Igipimo cyacyo cyo gukomera ni 3 × hejuru ya 316SS. Ibiciro byo kugaburira bigabanuka 40% nyuma yambere yambere. Igikoresho cyubuzima kiragabanuka niba umuvuduko ukonje uguye munsi ya 70 bar. Twabimenye uburyo bukomeye bwo gutunganya AMS 5387 cobalt-nikel nozzles ya hydraulic ya hydraulic yumuvuduko ukabije - kugeza igihe twahindukiye kumuvuduko mwinshi binyuze muri spindle coolant, ceramic-carbide yinjizwamo karbide hamwe na geometrike nziza, hamwe n'inzira zidahwitse zigabanya igihe cyo gutura.
Ikigo cyacu cyujuje ISO gikora ibigo 5-byo gutunganya ibikoresho byo gusya byimbitse-gusya byimbitse-nkibice bitemba byimbere byimbere byumuvuduko ukabije kugeza kuri 420. Duhuza uburyo bwo kuvura ubushyuhe * hagati y * ibikorwa iyo bikenewe: imashini itoroshye → igisubizo anneal → guhangayikisha → kurangiza imashini → imyaka ikomera. Kureka urwo rutonde bishobora kugoreka cyangwa imbaraga zumusaruro zidahuye. Abakiriya basibye isuzuma ryubwubatsi bakunze kubaza bati: "Kuki icyiciro cyacu cya mbere cyatsinze CMM ariko bikananirana guturika?" Igisubizo ni gake gushushanya-ni inzira yubushyuhe-bwa mashini.
Shira + Imashini = Imikorere-Isi Yukuri Urashobora gupima
Inconel 718 ntabwo ari impimbano cyangwa yakozwe gusa. Kubice binini, byubatswe muburyo bukomeye - urufatiro rwa pompe, imashini ya shitingi ya shitingi, imibiri ya valve yo hanze - gushora imari bitanga ishusho-hafi ya net hamwe n’ingano nziza. Ariko gukina wenyine ntibihagije. As-cast isura ibura umunaniro ukenewe mubice bizunguruka. Niyo mpamvu ibyacu Uruganda rwa Inconel 718 ikomatanya gushora imari hamwe na CNC irangiza neza: guta kuri ± 0.3 mm, hanyuma imashini ifunga imashini, ifite ibinyamakuru, hamwe nudupapuro kugeza kuri ± 0.008 mm hamwe na GD&T yuzuye.
Turakomeza guhuza tekinike hamwe nabatanga ibikoresho kubigenzura ingano (ASTM E112), igipimo cyo gushyiramo (ASTM E45), nibirimo delta-ferrite. Buri casting yakira igenzura rya radiografiya (ASTM E94) hamwe no gupima amazi yinjira (ASTM E165). Nta na kimwe kidasanzwe - ndetse no kuri prototypes. Kuberako mubikomoka kuri peteroli & gazi cyangwa munsi yinyanja, cluster imwe ya porosity kuri riser risa ntabwo ari "gutandukana kworoheje." Nukunanirwa kumurima utegereje kubaho.
Guhitamo Inconel yawe 718 Umufatanyabikorwa: Batatu badashyikirana
Mbere yo gushyira umukono kuri PO, baza ibibazo-usabe ibimenyetso:
- Urashobora kunyereka ibiti byawe bitatu bya nyuma Inconel 718? Ntabwo ari ubushyuhe gusa - ahubwo ni itanura ryikirere, igipimo cyinshi, igihe cyo gushiramo, nigipimo cyo gukonja kuri AMS 2750E.
- Ukora nyuma yubushyuhe-buvura microstructure verisiyo? Dukora SEM / EDS kumirongo yambukiranya kugirango twemeze γ ′ imvura igabanuka no kubura δ -cyiciro kumupaka wingano.
- Nibihe bihe bibi cyane byo kuyobora mugihe cyibice 15 byamazu ya silinderi ya mm-220 ya diametre-hamwe nibikoresho byuzuye, raporo za CMM, hamwe na NDT? Igisubizo cyacu ni iminsi 28. Ntabwo ari “ibyumweru 4-6.” Ntabwo “biterwa.” Turabikurikirana mugihe nyacyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ntabwo yihagararaho nka "Inconel 718 uruganda" rwo kwamamaza. Turi umwe - kubera ko burimunsi, abakanishi bacu bahindura ibiryo bashingiye kumyambarire yigihe nyacyo cyo kwambara, abanya metallurgiste bacu basuzumisha ibyasomwe bisomwa nibisubizo byikizamini, kandi itsinda ryacu rya QA ryasinyiye gusa nyuma yikizamini cyimikorere gihuye nabakozi bashinzwe. Ngiyo itandukaniro riri hagati yo gushakisha no gukemura.
Niba umushinga wawe utaha usaba ibice bya Inconel 718 bikomeza amasaha 10,000 kuri 600 ° C, funga neza kuri 400 bar, cyangwa kuzunguruka udatezutse kuri 1.800 rpm - tangira hamwe numufatanyabikorwa wizewe uba mumatanura yabo, ntabwo ari kurubuga rwabo. Uburenganzira Uruganda rwa Inconel 718 ntabwo isezeranya gutungana. Itanga ibizagerwaho - kimwe cyavuwe nubushyuhe, cyakozwe neza, igice cyakurikiranwa icyarimwe.
