Lapho onjiniyela becacisa ukwakhiwa kwesikhunta segobolondo sezingxenye zensimbi ezinembayo, abagcini nje ngokukhetha inqubo—bakhetha indlela eya ekuzinzeni kohlangothi, ukwethembeka kwendawo, kanye nesakhiwo esincane esiphindaphindwayo ezingxenyeni ezisebenza ngaphansi kwengcindezi enkulu, izinga lokushisa, noma ukuguga. A igobolondo isikhunta casting ifektri kumele ngenze okungaphezu kokuthela insimbi encibilikisiwe egobolondweni lesihlabathi eliboshwe nge-resin. Kumelwe ihlanganise isilawuli se-metallurgical ngokulungela komshini—ikakhulukazi uma ingxenye iyindlu yephampu ye-cobalt-alloy elinganiselwe ngamabha angu-350 noma umzimba wamavalvu we-AMS 5387 odinga ukuthobela ±0.02 mm GD&T.
Kungani I-Shell Mold Casting Iletha Lapho Ezinye Izinqubo Zizabalaza
Ukubumba amagobolondo kuhlezi phakathi kokusakazwa kwesihlabathi nokutshala imali: kushesha kune-wax elahlekile, ukubekezelela okuqinile kunesihlabathi esiluhlaza, futhi kuyingozi kakhulu kunegobolondo le-ceramic lokugijima kwezimboni zevolumu emaphakathi. Amandla aso alele egobolondweni elincanyana, eliqinile—imvamisa engu-6–10 mm ukujiya—okwakhiwa ngokumboza iphethini yensimbi eshisayo (180–250°C) ngesanti ye-phenolic resin-coated silica. Umphumela? Ukuphela komhlaba kwe-Ra 2.5–6.3 μm, ukubekezelela komugqa kufika ku-±0.3 mm ezicini ezingaphansi kuka-300 mm, kanye nemfuneko encane yokusalungiswa (0.5°–1.5°). Kodwa lezo zinombolo zisho okuncane ngaphandle kwesiyalo senqubo.
Sibone amakhasimende eshintsha ukusuka ekubunjweni kwesihlabathi ukuya ekubumbeni amagobolondo kuphela ukuze abhekane ne-warpage ezindlini ezinkulu zamasilinda-kwaze kwaba yilapho ebona ukuthi imbangela kwakungesona isikhunta, kodwa ukuqondanisa okuyisisekelo okungahambisani phakathi nokuhlanganiswa kwegobolondo. Esikhungweni sethu e-Qingdao, isethi ngayinye yegobolondo iqinisekiswa ngokuqondaniswa kwe-optical ngaphambi kokuvala. Yonke inqwaba yesihlabathi esimbozwe nge-resin ihlolelwa ukugeleza, amandla aqinile, nezinsalela zokutubeka. Futhi konke ukuphonsa okuthululwayo kuyaphola ngaphansi kokugeleza komoya okulawulwayo—hhayi ukucisha ngenkani—ukuze kunqandwe ukunqwabelana kwengcindezi okusele ezigabeni ezinengxubevange ephezulu.
Ukuhlanganisa Okuqondile Akuxoxiswana Ngezingxenye Ezibalulekile Ezibalulekile
Ukubumba igobolondo kukodwa akuqinisekisi i-valve yokucindezela esebenzayo. Okubalulekile ukuthi kwenzekani ngaphambi nangemuva: ukulandeleka kwezinto, ukuvumelanisa ukwelashwa kokushisa, kanye nencazelo yedatha elungele i-CNC. Yingakho iqiniso igobolondo isikhunta casting ifektri kufanele ibe ngumnikazi—noma ibuse ngokuqinile—iketango eligcwele.
- I-Pre-cast: I-T800 eqinisekisiwe ye-cobalt-based alloy ingots, eqinisekiswe nge-PMI ne-OES; usayizi wokusanhlamvu olawulwa nge-ladle metallurgy kanye nokuqapha izinga lokushisa elithelayo (±5°C ukubekezelelana)
- Ngesikhathi sokulingisa: Isithombe sesikhathi sangempela esishisayo sendawo yesikhunta ukuze kutholwe izindawo ezishisayo zendawo ezibangela ukuncipha okuncane ezingxenyeni zodonga oluncane
- I-post-cast: Ukunciphisa ingcindezi ezithandweni ezilawulwa emoyeni, kulandelwa ukuhlolwa kwe-CMM ye-3-eksisi *ngaphambi* komshini—kusetshenziswa idatha ye-as-cast ukuze kuqinisekiswe ukuhlanekezela
Lokhu kuhlanganisa kuqeda ukukhishwa kwesandla lapho ukukhukhuleka kobukhulu bunqwabelana khona. Lapho ikhasimende lisithumelela umdwebo wezindlu we-piston pump cylinder one-bores ezibucayi ezingu-12 kanye nokubekezelela isikhundla esingu-0.015 mm, sibambe ukuphazamiseka phakathi kwemvume yokuncipha nesitoko sokugcina somshini ngesikhathi sokubuyekezwa konjiniyela—hhayi ngemva kokuhlolwa kwesihloko sokuqala.
I-Material Mastery Ichaza Imingcele Yokusebenza
Ama-alloys e-cobalt-nickel afana ne-AMS 5387 awaziphathi njengo-316 okungenasici. Izinga labo eliphezulu lokuqina komsebenzi, ukusebenza okuphansi kwe-thermal, nezigaba ze-carbide ezibayo zidinga imingcele yokusakaza elinganiselwe *yalelo khemistri*—hhayi izilungiselelo ezijwayelekile ze-“superalloy”. Amanye ama-Foundries aphatha wonke ama-cobalt alloys ngokufanayo. Asazi.
Empeleni, lokhu kusho ukulungisa ukujiya kwegobolondo ngo-±1.5 mm kuye ngemodulus yesigaba, ukulungisa isivinini sokungena ukuze kugwenywe ukuguguleka kwemibhobho emihle, nokubamba isikhathi sokuqiniswa phakathi kwamasekhondi angu-90 kumapulaki angaphansi kobubanzi obungu-40 mm. Senze imibhobho engaphezu kuka-17,000 ye-AMS 5387 kusukela ngo-2021. Iqoqo ngalinye lihlanganisa ukulandeleka okugcwele kokushisa, imibiko yokuhlola eqinile nge-ASTM E8 ngayinye, nezithombe ze-microstructure ezibonisa ukusabalalisa okufanayo kwe-eutectic carbide—awekho amaqoqo angawodwa eduze nezingeniso zamasango.
Lelo zinga lokulawula lihlukanisa umphakeli othumela ukusakaza kusukela kulowo othumela *izingxenye zokusebenza eziqinisekisiwe*. Uma uhlelo lwakho lokusebenza lubandakanya ukulayisha okujikelezayo okungaphezu kuka-200 MPa noma ukuchayeka kuwoyela negesi anothile nge-H₂S, ukungaguquguquki kwezinto akuyona inketho—kuwumugqa wokuqala wokuvimbela ukwehluleka.
Ukukhetha Uzakwethu Olungile Kusho Ukubuza Imibuzo Elungile
A igobolondo isikhunta casting ifektri kufanele iphendule lezi—hhayi ezincwajaneni zokumaketha, kodwa ezingxoxweni zobunjiniyela:
- Ungakwazi ukungibonisa imibiko yakho yokugcina yenqwaba emithathu ye-AMS 5387—okuhlanganisa nosayizi wokusanhlamvu, ivolumu ye-carbide %, nokuhlukaniswa kwe-interdendritic?
- Ingabe uyaqinisekisa ijiyomethri ye-as-cast *ngaphambi* komshini, usebenzisa idatha yomdabu yokulingisa—hhayi nje ubukhulu bengxenye yokugcina?
- Singakanani isisindo sakho esiphezulu sesiqephu esisodwa sama-cobalt alloys abunjwe ngegobolondo—futhi ukuphatha kanjani ukuhluka kwesisindo esishisayo kulo lonke lolo bubanzi?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihlangabezana naleyo mibuzo ngezinqubo ezibhaliwe, hhayi izithembiso. Indawo yayo ethobela i-ISO isekela ukubumba igobolondo lensimbi, insimbi, insimbi, i-cobalt-nickel alloys esebenza kahle kakhulu—enemishini ye-CNC, ukwelashwa kokushisa, nokuqedwa kwendawo ngaphansi kophahla olulodwa. Isebenzela ama-OEM asebenza ngohydraulic, izihlanganisi zemishini yasolwandle, nabakhi bephampu abakhethekile kulo lonke elaseNyakatho Melika, i-Europe, naseNingizimu-mpumalanga ye-Asia—hhayi njengomthengisi, kodwa njengesandiso seqembu labo lobunjiniyela bokukhiqiza.
Uma ubheka phambili, imboni izodinga ukuhlanganiswa okuqinile kwezinqubo zokulingisa nezokwengeza, isitifiketi esinwetshiwe sezinhlelo zokusebenza ze-nuclear-grade kanye ne-API 6A, kanye nokuqinisekiswa okuphindwe kabili kwedijithali kokusakazwa kwendlela egelezayo eyinkimbinkimbi. Isizukulwane esilandelayo igobolondo isikhunta casting ifektri ngeke nje iphindaphinde i-geometry. Izobikezela ukusebenza-kuqale ngegobolondo.
