Lapho onjiniyela becacisa a steelcasting Foundry factory, abagcini ngoku-oda insimbi kuphela—bazibophezela ekuzinzeni kobukhulu ngaphansi kwebha engu-300, ubuqotho besakhiwo esincane ngemva kokuhamba ngebhayisikili elishisayo, kanye nokungabekezeleli nhlobo ukuqina ezindaweni ezigqoke kakhulu. Sibone amaphrojekthi amaningi ebambezelekile ngoba abahlinzeki bempahla baphatha insimbi “njengenye nje ingxubevange.” Akuyona. Izinsimbi ze-low-alloy ziqhekeka ngaphansi kokucisha ngokushesha. Amabanga angenasici njenge-CF8M ahlukanisa uma amazinga okupholisa isikhunta ekhukhuleka ngo-±5°C. Futhi izingxenye zephampu ezisekelwe ku-cobalt—ikakhulukazi i-AMS 5387 noma i-T800—zidinga ukuqhubeka kwe-metallurgical kukho konke ukushisa, hhayi nje ukuthobela ishidi elithile.
Kungani Ukusakazwa Kwensimbi Kwehluleka Ngaphambi Kokwenza Umshini Ngisho Nokuqala
Ukwehluleka okuningi kubuyela emuva ezikhaleni ezintathu ezigwemekayo: ukuthola izinto ezibonakalayo ngaphandle kwesitifiketi sezinga lenqwaba, idizayini yesikhunta sesihlabathi esishaya indiva ukuqina okuqondile ezindlini eziwugqinsi, namashejuli okwelashwa okushisa ahlukaniswe nengxenye yangempela yejometri. Esikhungweni sethu se-Qingdao, sihlola amabhilidi angu-316L angenayo ukuze sithole okuqukethwe kwe-ferrite *ngaphambi* kokuthela—hhayi ngemva kwalokho. Senza imephu ama-thermal gradients ekubunjweni kwesihlabathi sisebenzisa ama-thermocouples ashumekiwe ngesikhathi sokuthululwa kwesivivinyo. Futhi asilokothi sisebenzise umjikelezo wentukuthelo ofanayo endaweni yephampu yepiston engu-45-kg kanye nomzimba wevalvu we-pressure engu-2.3-kg. Usayizi owodwa awulingani lutho ekubunjweni kwensimbi okunembayo.
Yingakho sihlanganisa ukuhlelwa kwenqubo yokusakaza ngokuqondile ekubuyekezweni kwe-GD&T. Uma ikhasimende lithumela umdwebo wezindlu zesilinda sensimbi engagqwali onokubekezelelana okungu-±0.05 mm kumabhore akhwezayo ayisithupha, asicaphuni nje ukwenza imishini. Siyabuza: Isango lingena kuphi? Imaphi amaphrinti abalulekile azoshintsha ngesikhathi sokushaqeka? Kungakanani ukuhlanekezela kwangemuva kokusakazwa okwenzeka ku-650°C? Lena akuyona imibuzo yetiyetha. Ziyalinganiswa—ekulingisini kwangempela, nedatha ye-CMM efakwe ngokuqhathaniswa nezindawo zangempela ze-CAD.
Ukuhlanganisa Okuqondile Okulawula Izinguquko Empeleni
Ukukhipha izinsiza, bese kwenziwa imishini, bese ukuqeda kudala ama-handoffs amathathu—kanye namathuba amathathu ephutha elinqwabelene. Eyethu steelcasting Foundry factory iqhuba utshalomali kanye nokusakazwa kwesihlabathi *esakhiweni esifanayo esiqinisekiswe i-ISO* lapho kusebenza khona izikhungo ze-CNC. Ipulaki ye-cobalt-nickel esakazwa ku-1,420°C ihamba ngokuqondile ekunciphiseni ukucindezeleka, bese ifinyelela kuma-axis amahlanu—konke kungakapheli amahora angu-48. Azikho ezokuthutha phakathi kwezindawo. Akukho ukulungisa kabusha. Azikho izithenjwa zedatha elahlekile.
Lokhu akulula-ukulawula okuqhutshwa yi-physics. Umehluko wokunwebeka okushisayo phakathi kwesihlabathi sesikhunta, insimbi encibilikisiwe, namapuleti afakwe ngomshini uyancishiswa uma zonke izinyathelo zenzeka ngaphansi kophahla olulodwa ngokuqapha okwabelwana ngakho kwemvelo. Silandelela umswakama we-ambient nezinga lokushisa le-ambient njalo ngehora—hhayi ngoba “umkhuba omuhle,” kodwa ngenxa yokuthi silinganisele ukuthi ukushwibeka okungu-3% kwe-RH kusishintsha kanjani isikhathi sokumisa sesikhunta esanele ukuze siguqule ubulukhuni bobuso ebusweni obubucayi bokuvalwa.
- Ukusakazwa kwensimbi komshini we-CNC: ≤0.015 mm ifomu lokuchezuka kuzibambi ezingu-300 mm
- Insimbi ye-sand-cast carbon (WCB): ukuhlukahluka kwamandla okuqinile < ±8 MPa ekushiseni okungu-10 okulandelanayo
- Investment-cast Stainless (CF3M): Ra ≤1.6 µm as-cast ezindaweni ezigelezayo—akukho ukugaya kwesibili okudingekayo
- Ingxubevange ye-cobalt ye-AMS 5387: ukulandeleka okugcwele kokushisa kuya ekushiseni, okuhlanganisa ilogi encibilikayo, ukuhlaziywa kwe-spectrographic, nokuqinisekiswa kosayizi wokusanhlamvu nge-ASTM E112 ngayinye.
Ukusebenza Komhlaba Wangempela, Hhayi Ukuthobela Amaphepha Kuphela
Abanye abahlinzeki bathumela izinsimbi zensimbi “ezinesitifiketi se-ISO 9001” esigxivizwe ohlwini lokupakisha—kodwa abakwazi ukukhiqiza umbiko wokuhlola owodwa oqinisekisiwe obonisa amaphrofayili okuqina kusisekelo sephampu esiwugqinsi ongu-120 mm. Senza njalo. Konke ukuthunyelwa kufaka phakathi umbiko wokuhlolwa kwezinto (MTR) onamanani aqinile, esivuno, amade, kanye nomthelela—akalwa kusikwa ikhuphoni *kusuka ekulingiseni okufanayo*, hhayi kubha yokuhlola ehlukile.
Siphinde siqinisekise ukusebenza kokusebenza ngaphambi kokuthunyelwa. I-winch center shaft roller ayihlolisiswa nje ububanzi. Izungeza ngo-1,200 rpm ku-load-dynamometer rig yethu kuyilapho ama-strain gauge eqapha ukuchezuka ezindaweni ezintathu zama-radial. Izindlu ze-valve yokucindezela azidluli ukuhlolwa kwe-hydrostatic ku-1.5 × ingcindezi yokusebenza. Ijikeleza izikhathi ezingu-5,000 ngokushaqeka okulingisa okushisayo—200°C kuya ku-25°C ngaphansi kwemizuzwana engu-90—bese ihlolwa ngokungena kodayi. Uma iqhekeka, siklama kabusha isistimu yesikhuphukeli—hhayi inqubo ye-NDT.
Ongakudinga Kuzakwethu Wokusakaza Ngensimbi
Ungakhathazeki ngokuthi "siphonsa insimbi." Buza esikhundleni salokho:
- Ungakwazi ukungibonisa amalogi okushisa amathathu okugcina okunikezwayo kwakho kwe-ASTM A216 Yebanga le-WCB—futhi uqinisekise ukuthi wonke athathwe emshinini ofanayo wokugaya?
- Ingabe ulingisa ukuqina ku-MAGMAsoft noma okufanayo ngaphambi kokugunyaza ukwakheka kwesikhunta?
- Ingabe ukuhlola kwakho kokugcina kwenziwa ku-CMM elinganiselwe—noma ngama-micrometer aphethwe ngesandla kanye namageji e-go/no-go?
- Uma ukusakaza kwehluleka ukuhlola okubonakalayo, ingabe uyakukhipha—noma wenze ukuhlaziya okuyimbangela ohlotsheni lokufakwayo, ukusatshalaliswa kwe-gas porosity, kanye nesikhala sezingalo se-dendrite?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uphendula ngoyebo bobane. Hhayi njengezimangalo zokumaketha—kodwa njengezinyathelo ezibhalwe phansi zokuhamba komsebenzi, ezibonakala kumarekhodi ethu okukhiqiza futhi eziqinisekiswa phakathi nokuhlolwa kwamakhasimende. Sakha izinsimbi zensimbi zamasistimu asebenza ngogesi asebenza amahora angu-18,000 ngaphandle kokushintshwa kophawu. Okwamaphampu asendaweni kawoyela abamba uketshezi olugcwele i-H₂S ku-120°C. Kumawintshi emoto yobunjiniyela aphakamisa imithwalo engamathani angu-8.5 ngaphansi kwezimo ezingaphansi kweqanda. Ukwethembeka akuyona inhloso. Kungumphumela wezinqubo ezilawulwayo-kukalwa, kuphindwe, kufakazelwe.
Uma i-oda lakho elilandelayo lokulingisa insimbi lidinga okungaphezu kokuvumelana kwe-dimensional—uma lidinga ukubikezelwa kwesakhiwo, ukungaguquguquki kwensimbi, nokuqinisekiswa kokusebenza—qala ngokubonakala kwenqubo. Hhayi izincwajana. Akuzona izitifiketi zodwa. Kodwa ukufinyelela kwesikhathi sangempela kumalogi okusakaza, amashadi okwelapha ukushisa, nemibiko ye-CMM. Kanjalo a steelcasting Foundry factory ithola indawo yayo kumaketango okunikezwayo okubalulekile.
