Uma uzwa 'i-ductile iron casting foundry', izingqondo eziningi zigxumela ngqo ensimbi ngokwayo—i-nodular graphite, izici zamandla aqinile. Leyo yinkulumo yempahla. Indaba yangempela, leyo enquma ukuthi ingxenye ithatha iminyaka engamashumi amabili noma yehluleke kabili, yenzeka ezindaweni ezimpunga: ukwakheka kwesistimu yokungena, isikhathi sokujova, indlela osingatha ngayo isikhunta ngemva kokunyakaziswa. Akukhona nje ukwenza ukulingisa; imayelana nobunjiniyela ingxenye eziphatha ngokubikezela ngaphansi kwengcindezi. Abathengi abaningi kakhulu, imbala onjiniyela, bayalungiswa embikweni wekhemistri futhi bageje yonke into eyenzekayo phakathi kwesithando somlilo nendawo ewumshini oqediwe.
I-Foundry Floor I-Chemistry Lab, Kodwa Hhayi Ngendlela Ocabanga Ngayo
Impela, sisebenzisa ama-spectrometer. Ukuhlaziywa kwe-ladle kokujwayelekile i-ductile iron Ibanga elifana ne-65-45-12 liqondile. Shaya ububanzi bakho bekhabhoni, i-silicon, i-magnesium. Amaphepha ahlanzekile. I-chemistry yangempela, noma kunjalo, iyasebenza futhi ingcolile. Kuwukuphela kwe-magnesium post-inoculation. Unefasitela—ngezinye izikhathi imizuzu nje—ukufaka leyo nsimbi egayiwe esikhunjeni ngaphambi kokuba umphumela wokwenza iziqhumane uwohloke. Ngike ngabona ukuthululwa lapho yonke into yayihamba kahle ephepheni, kodwa ukubambezeleka kulayini kubangele ukwehla kwezinga lokushisa nokugcwalisa okuvilaphayo. Umphumela? I-Marginal graphite morphology ezingxenyeni eziwugqinsi. Ingxenye ingase idlule ekuhlolweni okuvamile, kodwa impilo yayo yokukhathala isengozini. Lolo ulwazi olungakhulunywa emsebenzini i-ductile iron casting foundry.
Kulapho amashumi eminyaka okusebenza, njengase-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ehumushela inani. Ngaphezu kweminyaka engama-30 ekulingiseni nasekukhiqizeni imishini, kungenzeka ukuthi bathulule, babona, yonke into. Leyo nkumbulo yesikhungo ibalulekile. Kusho ukuthi abalawuli benqubo yabo abalandeli nje imanuwali; bayakubona ukubukeka kwensimbi, umsindo wensimbi eshaya i-cope, izimpawu ezicashile okungenzeka ukuthi isistimu ezenzakalelayo igeje. Ngoba i-ductile iron, lokhu kuhlolwa kwezinzwa kuyisipele ku-instrumentation, isango lokugcina, lekhwalithi yomuntu.
Futhi akukhona nje mayelana nokuthela insimbi. Ake sikhulume isikhunta. Ekubunjweni kwegobolondo, i-QSY ibala njengokukhethekile, i-sand resin chemistry kanye nokuphulukiswa kuthambile ngendlela efanayo. Ukuchezuka okuncane esilinganisweni se-catalyst kungenza igobolondo libe brittle kakhulu noma lithambe kakhulu. Igobolondo eliqinile lingaqhekeka ngesikhathi liphathwa, libangele amaphiko kanye nemithambo ekubumbeni. Igobolondo elithambile lingahlanekezela ngaphansi kokushisa nesisindo sensimbi, okuholela ekukhukhuleni kobukhulu. Ufunda lokhu kuhlobana kuphela ngokusebenzisa izinkulungwane zesikhunta, ukulandelela ukuchezuka, nokukuhlobanisa nokulimala kokugcina kokulingisa. I-loop yempendulo eqhubekayo, engcolile.
Lapho Ukusakaza Kuphela Futhi Nomshini Uqala (Noma, Umthungo Okungafanele Ube Khona)
Lesi yisilwane esifuywayo esikhulu. I-Foundry esebenza endaweni engenalutho evela kumashini iyisikweletu. Idizayini yephethini yokulingisa kufanele ilindele izidingo zohlelo lwe-CNC. Izosungulwa kuphi i-datum yokuqala? Ingabe ikhona indawo ehlanzekile, efana ne-cast of primary clamping? Ingabe indawo yomugqa wokuhlukanisa idala ifleshi eliphazamisa ukulungisa? Ngithole ukulingisa okuvela kwabasunguli abahloniphekile abebengenakulinganiswa ngaphandle kokuklama i-Frankenstein, konke ngoba unjiniyela womsunguli akakaze akhulume nomakhinikhi.
Ukusebenza okudidiyelwe okufana nama-QSY, okunikeza kokubili ukulingisa kanye nemishini ye-CNC ngaphansi kophahla olulodwa, kuxazulula lokhu ngokwemvelo. Isitolo sabo sephethini cishe sisengxoxweni eqhubekayo nabahleli besikhungo sabo somshini. Lapho beklama umgijimi kanye nesistimu yesikhuphukeli se- i-ductile iron cast, bacabanga nokuthi bazoyibeka kuphi ukuze ikhishwe kahle emshinini wokugaywa, kusale indawo esebenzayo. Bangakwazi ukuhlela ukwenza izibonelelo zesitoko ezingokoqobo, hhayi izinombolo zezincwadi zokufunda kuphela. Lokhu kusebenzisana kulapho wonga khona imali yangempela nesikhathi, ugwema ama-imeyili angena emuva naphambili phakathi kwabathengisi abahlukene besolana ngengxenye engaphandle kwencazelo.
Isibonelo esisebenzayo: i-hydraulic valve body esisebenze kuyo. Amavesi angaphakathi ayeyinkimbinkimbi, edinga ukunemba ukubunjwa kwegobolondo ukubamba ijometri. Ubuso bophawu olubucayi budinga ukuqedwa kwe-Ra 0.8. I-Foundry eyayiphonsa kuphela ishiye isitokwe esinzima ebusweni, okwathi ngesikhathi somshini kubangele ukuguga okuqinile nokungalingani kwamathuluzi ngenxa yongqimba lwangaphezulu oluqinile ngenxa yokupholisa ngokushesha. I-foundry-machinist edidiyelwe, nokho, ingalungisa inqubo yokupholisa (mhlawumbe isebenzisa imikhono evikelayo kulezo zikhuphukeli) ukuze kuqinisekiswe ukujula kokuqina okufanayo, bese ikumshinisa ngendlela yamathuluzi efanisiwe bese ifaka ibanga. Umphumela waba isiphetho esingcono, ukuphila kwamathuluzi okude, nengxenye ethembekile. Lokhu akuwona umlingo; ukuxhumana kufakwe ohlelweni.
Umbuzo Wengxubevange: Lapho I-Ductile Iron Inganele
I-Ductile iron iyihhashi lokusebenza, kodwa ishidi le-specpe aliyitsheli yonke indaba ngaso sonke isikhathi. Ukulimala? I-500 Brinell ene-ductile iron eqinile ingase isebenze. Kodwa engeza umthelela? Lowo ngumdlalo ohlukile. Kwesinye isikhathi udinga ukungena kulawo ma-alloys akhethekile akhulunywa nge-QSY—ama-alloys asuselwa ku-nickel noma asekelwe ku-cobalt ukuze aguge kakhulu futhi agle. Ikhono le-Foundry lapha liyasitshela. Ukuncibilika nokuthulula lawa ma-alloys kudinga ama-linings ahlukene, izilawuli eziqinile zomkhathi, kanye nezindlela zokuthela ezihluke ngokuphelele. I-Foundry enethezeke ngalezi zinto ezisetshenziswayo ivamise ukuba nokuqeqeshwa okuqinile okuphuma igazi kubuyele ezingeni lazo i-ductile iron umsebenzi. Izinqubo zabo zokulawula ukungcola zizoqina, ukuqapha kwazo okushisayo kucace kakhudlwana.
Ngikhumbula isixhumi sephampu sendawo enosawoti. Umcabango wokuqala kwakuyi-austenitic ductile iron (Ni-Resist). Kuhle, kodwa ekuhlolweni kwensimu, inhlanganisela yokugqwala okubangelwa i-chloride nokuguguleka kwe-cavitation kudle ngokushesha kunalokho obekulindelwe. Isixazululo, esakhiwe nge-Foundry metallurgist, kwaba ukushintshela ekubunjweni kwensimbi engagqwali eyi-duplex. Inselele ibe ukuphakela insimbi eshwabene ngendlela ehlukile futhi ejwayele ukudabuka kakhulu. Kwadingeka siklame kabusha lonke uhlelo lokuphakela nokupholisa. Kube ukwehluleka okuholele esixazululweni esingcono, kodwa kwakudinga umsunguli ozimisele futhi okwazi ukuzungeza, ukuqhuba izivivinyo, nokucabanga ngale kwekhadi lebanga elijwayelekile. Akuzona zonke izitolo ezinalowo mkhawulokudonsa.
Lokhu ukuhlukahluka kokukhetha kwezinto ezibonakalayo. Kuhle isisekelo Uzakwethu akamane nje amukele isicaciso sakho sezinto ezibonakalayo; bayayibuza. Bangase babuze ngendawo yesevisi yangempela, imijikelezo yokulayisha, amandla okushaqeka okushisayo. Ngokusekelwe kulokho, bangase baphakamise ukushintshwa kwebanga okucashile—kusuka ku-ferritic kuya ku-pearlitic matrix ku-ductile iron, ngokwesibonelo, ukuze kuguge kangcono ngezindleko ze-ductility encane. Leyo ngxoxo inesisindo sayo ngegolide.
Isipoki Emshinini: Ukuzinza Kwe-Dimensional kanye Nokucindezeleka
Omachini bazonda izimanga. Okumangazayo okubi kakhulu ukusakaza okunyakazayo ngesikhathi somshini noma, okubi nakakhulu, ngemva kokuthunyelwa. Ingcindezi eyinsalela ku i-ductile iron cast isipoki leso. Ivela ekupholiseni okungalingani, kusukela ku-shakeout enolaka kakhulu, ekwelapheni ukushisa okungafanele. Awukwazi ukukubona njalo embikweni we-CMM kusanda kuvela ku-Foundry.
Ukulungiswa okujwayelekile ukudambisa ingcindezi yokushisa. Kodwa umjikelezo ubaluleke kakhulu. Akulona nje ibhokisi lokumaka. Ngike ngabona izitolo zisebenzisa umjikelezo wejenerikhi kuzo zonke izingxenye, okuyinto engenamsebenzi kakhulu. Umjikelezo osebenzayo udinga ukucabangela ijometri yengxenye, ukuhluka kogqinsi kwesigaba, nomlando wokupholisa wokuqala. Indlu eyinkimbinkimbi, enezintambo idinga iphrofayili ehlukile yokukhuphuka, ukucwiliswa, kanye nokupholisa kune-slug esiqinile. Ukusebenza okuhlanganisiwe kunenzuzo enkulu lapha. Bangakwazi umshini ucezu lokuhlola, balinganise ukuhlanekezela, bese bebuyela emuva futhi balungise umjikelezo wokukhulula ingcindezi, futhi balungise inqubo yokusakaza ngokwayo, ku-loop evaliwe. Babona umphumela wokugcina wezinqumo zabo zokuphonsa.
Sasinogearbox wezindlu, into eyibhokisi yangempela enogqinsi olungalingani. Yayilokhu inyakaza phakathi nomsebenzi wokugcina oyisicefe wezihlalo ezithwele. Umsunguli ugcizelele ukuthi inqubo yabo ilungile. Ukuphumelela kufike lapho senza isheke elilula kodwa elidla isikhathi: silinganise izilinganiso ezibucayi kusampula yenqwaba njengokusakazwa, ngemva kokunyakaziswa, ngemva kokuqhuma kwesibhamu, nangemuva kokukhululeka kwengcindezi. Ukunyakaza okukhulu akwenzekanga ngesikhathi sokuphumula kwengcindezi, kodwa ngesikhathi sokuqhuma kwesibhamu esinamandla. Isixazululo kwaba ukushintshela kumidiya yokuqhuma engenamthelela omncane kanye nomjikelezo omnene waleyo ngxenye ethile. I-Foundry eyabalingisi kuphela ayikutholi lokhu. I-Foundry nayo imishini ithola impendulo eqondile, ebuhlungu futhi iphoqeleke ukuyixazulula.
