Uma uzwa i-N08825, noma i-Alloy 825, umcabango osheshayo uvame ukuthi 'ingxube ye-nickel-iron-chromium engagqwali'. Leyo yincwadi yokufunda. Kodwa emhlabeni we-Foundry kanye nemishini, lelo lebula alikaze lizinwaye. Indaba yangempela ayikho eshidini elicacisiwe kuphela; kusekuthelweni, ekusikeni, ekuphatheni ukushisa, kanye nezinqumo ezincane ezingenakubalwa ezihlukanisa ingxenye ephumelelayo nenqwaba yezilahleko ezibizayo. Ngibone amaphrojekthi amaningi kakhulu ekhubeka ngokuyiphatha njengenye nje engenabala. Akunjalo.
I-Foundry Floor Reality ene-825
Ukusakaza i-N08825 yilapho ithiyori ihlangana khona nomlilo, ngokoqobo. Okuqukethwe kwe-nickel ephezulu kukunikeza lokho kumelana okumangalisayo ekwehliseni ama-acids kanye nokuqhekeka kokugqwala kwengcindezi, kodwa futhi kuyenza ibe yisilo segobolondo noma ukutshala imali. Iphethini yokuqinisa i... finicky. Awukwazi ukusebenzisa i-gating efanayo kanye nesistimu yokukhuphuka ongayisebenzisa engxenyeni engenasici engu-316 futhi unethemba lokungcono kakhulu. I-shrinkage ihlukile, i-fluidity izizwa ihlukile. Ekuqaleni, sasinenqwaba yezinye imizimba yama-valve ehlala ibonisa i-micro-porosity ezingxenyeni eziwugqinsi. I-chemistry yayiphelele ngokwe-cert, kodwa isakhiwo sasingazwakala.
Inkinga ilandelelwe emuva ekuthululeni izinga lokushisa kanye nokushisa kwangaphambili kwesikhunta. Besiyiqhuba ipholile kakhulu, sizama ukunciphisa ukulahleka kwensimbi kanye ne-oxidation, kodwa ngo-825, lokho kubamba amagesi futhi kudala izinkinga zokuncipha. Udinga ukushisa okuphezulu ngokwanele ukuze uyigcine izacile, kodwa ingabi phezulu kakhulu ushisa izakhi zengxubevange noma uhlasele igobolondo le-ceramic kabuhlungu. Iwindi elincane. Uzakwethu onjengaye I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), ngeminyaka yabo engamashumi amathathu kugobolondo nokufaka utshalomali, uthola lokhu. Cishe babone umdanso ofanayo. Okuhlangenwe nakho kwabo kuwo wonke ama-alloys akhethekile kusho ukuthi kungenzeka basungule imigomo yejika lokuthulula kanye ne-mold prep eqondene nalawa mabanga asekelwe ku-nickel, okuyingxenye yempi enqotshiwe.
Ukwelashwa kokushisa kwangemuva akuxoxiswana. I-As-cast 825 inama-carbides nama-intermetallics aphihliza izakhiwo zayo zokugqwala. Udinga leso sixazululo sokuvala cishe ku-°F kulandelwe ukucisha okusheshayo ukuze ubuyisele yonke into kusixazululo esiqinile. Yeqe noma ungcolise izinga lokucisha, futhi ingxenye ingase idlule isheke lobukhulu kodwa izohluleka ensimini, ngokwesibonelo, endaweni egcwele i-chloride. Kuyisinyathelo esibalulekile esengeza izindleko nesikhathi, futhi awukwazi ukunqamula amakhona.
Imishini: Lapho Ithuluzi Lizofa Khona (Uma unganakile)
Uma ukuyisakaza kuwubuqili, ukwenza i-N08825 yilapho uzuza khona imivimbo yakho. Ukuyibiza ngokuthi 'gummy' kuwukubukela phansi. Ayikhiphi; kwakha lezi zinsalela ezinde, ezinezintambo, eziqinile ezingagoqa yonke into futhi zidale umonakalo. Izinga lokuqina lomsebenzi liyamangalisa. Ukufakwa okubuthuntu kancane noma ukusika okukhanyayo kakhulu kuzovele kucwebezelise phezulu, kukwenze lukhuni futhi kwenze iphasi elandelayo ibe nzima nakakhulu, okuholela ekungasebenzini ngokushesha kwamathuluzi kanye nomonakalo ongaba khona ngaphansi komhlaba engxenyeni.
Sifunde kanzima ngomsebenzi we-pump shaft. Usebenzisa amamaki e-carbide ajwayelekile ngokungenasici? Inhlekelele. Ukuphila kwamathuluzi kukalwa ngemizuzu, hhayi amahora. Indawo engaphandle yayingenhle, futhi sasilokhu silwa nokukhukhuleka ngenxa yokushisa nokucindezela. Impumelelo iqhamuke ekushintsheni emabangeni akhethekile—ama-carbide aqinile, abukhali abukhali anama-coating akhethekile, nezibambi zamathuluzi eziqinile ezine-overhang encane. Ukupholisa akukona nje okokupholisa lapha; okokugcoba nokuphula leyo chip. Ingcindezi ephezulu, into epholisayo ngethuluzi cishe iyadingeka kunoma iyiphi ivolumu ebucayi.
Lapha yilapho ukuhlanganiswa kwesitolo esisebenza ngokugcwele kubalulekile. Inkampani ephethe kokubili ukulingisa kanye ne CNC imishini endlini, njengamasevisi achazwe kuwo https://www.tsingtaocnc.com, inenzuzo ehlukile. Omashini bakhona ababoni ibhilethi eluhlaza, efakwe emanzini; basebenzelana nezabo izingcweti zabalingisi. Bayazi isimo sesikhumba esinjenge-cast, ukuhlukahluka kokuqina okungenzeka, futhi bangalungisa isu labo lomshini kusukela ekudluleni kokuqala. Lolu lwazi lwe-close-loop luvimbela okuningi kokuqagela nokubulala amathuluzi okwenzeka lapho isitolo somshini sithola 'ibhokisi elimnyama' elisakazwa emthonjeni ongaziwa.
I-Alloy Selection Trap: Lapho i-825 Ingeyona Isixazululo
Nansi igebe elivamile: icacisa i-N08825 ngoba iyingxubevange eyaziwayo 'emelana nokugqwala' ohlwini, ngaphandle kokuhlaziya indawo ezungezile ngokugcwele. Yinhle kakhulu endaweni ye-sulfuric ne-phosphoric acid, ilungele amanzi olwandle. Kodwa uma ubhekene nama-chloride ashisayo, agxilile noma izingxube ezithile ze-asidi oxidizing, kungase kube nezinketho ezingcono ezifana nama-alloys e-molybdenum aphezulu noma i-titanium. Ngikhumbula iphrojekthi yesikrufu sokucutshungulwa kwamakhemikhali lapho iklayenti laphikelela khona ku-825 ngokusekelwe ku-spec endala. Ukubuyekezwa kokusakaza kwenqubo kwangempela, okwakunezinsalela ze-ferric ne-cupric chloride, kubonise ukuthi sasidlala ngothando ngokugqwala kwe-pitting. Kwadingeka sihlehle futhi siphakamise enye indlela.
Yingakho ikhono lempahla libalulekile. Umphakeli obala ulwazi ngebanga le ama-alloys asekelwe ku-nickel futhi ama-alloys asekelwe ku-cobalt ayibonisi nje imenyu. Kusho ukuthi bona (noma ama-metallurgists abo) bake babandakanyeka kulezi zingxoxo ngaphambilini. Bangabheka okuphrintiwe futhi babuze imibuzo efanele mayelana nezinga lokushisa, i-pH, ama-ion angcolile, namazinga okucindezeleka. Leyo ndlela yokubonisana isindisa wonke umuntu ekuhlulekeni kwenkundla phansi komugqa.
Kuphinde kuthinte ukwenziwa kwezinto. Kwesinye isikhathi, ukushintshwa okuncane ekwakhiweni—irediyasi evulekile, uguquko ekujikeni kodonga—kungenza ukusakaza kanye nokwenza ama-machining okungu-825 kube lula kakhulu ngaphandle kokuphazamisa umsebenzi. Isitolo esenza izingxenye zokuphrinta kuphela ngeke sinikeze lokho. Lowo onjiniyela inqubo yokukhiqiza kusuka kokubalulekile kuya phezulu.
Ukushisela kanye Nokwenziwa: Indawo Efihlekile Yokucindezeleka
Izingxenye azivamile ukuphonswa futhi zenziwe ngomshini. Ngokuvamile badinga ukushiselwa kwezinye izingcezu, noma bashiselwe imibhobho. I-N08825 ithathwa njengeshiselwe, futhi kunjalo, kodwa 'i-weldable' akusho 'ukuthethelela'. Udinga insimbi yokugcwalisa efanayo (njenge-INCO-Weld 825 noma efanayo), kanye nokulawula okuqinile kwezinga lokushisa eliphakathi nendawo nokokufaka ukushisa. Ukushisa okukhulu kakhulu, futhi ungangenisa lawo ma-carbides endaweni ethinteke ukushisa (HAZ), udale ibhande elincane lezinto ezilahlekelwe ukumelana nokugqwala futhi libe brittle.
Sakha ithangi elikhulu kanye, futhi ngemva kokuhlolwa kwamanzi, kwavela imifantu emihle ku-HAZ eduze kwemithungo eminingi. Ukuhlolwa kwesidumbu kubonise ukuthi kwakuyinhlanganisela yekhemikhali yensimbi yokugcwalisa kancane futhi ivumela izinga lokushisa le-interpass likhuphuke. Insimbi yokushisela yona yayilungile, kodwa indawo eseceleni kwayo yayisengozini. Ukwehluleka okucashile okungabonisi kuze kube yilapho ingaphansi kwengcindezi noma isevisi. Manje, umthetho uwukufaneleka okugcwele kwenqubo futhi, ezingxenyeni ezibucayi, mhlawumbe ukwelashwa kokushisa kwangemva kokushisela ukuze kuxazululwe kabusha i-HAZ, nakuba lokho ngokuvamile kungasebenzi ekwakhiweni okukhulu.
Lena enye ingxabano yokukhiqiza okuhlanganisiwe. Uma umdayisi ofanayo owenza ukulingisa nomshini futhi ephatha ukwakhiwa, ungumnikazi wawo wonke umlando wokushisa wengxenye. Bazi kahle ukuthi impahla ikusiphi isimo ngaphambi kokuthi umshiseli ayithinte, okuwuguquko olukhulu olususwe ku-equation.
Ukuqinisekiswa Kwekhwalithi: Themba, kodwa Qinisekisa Ngokungapheli
Nge-alloy efana nalena, amaphepha (Izitifiketi Zokuhambisana) awumugqa wokuqala, hhayi umugqa wokugcina. I-melt cert ikutshela ukuthi ikhemistri yayikhona lapho. Ayikutsheli ngobuqotho bokulingisa kokugcina noma imiphumela yomshini. I-Positive Material Identification (PMI) ekutholeni, futhi engxenyeni eqediwe, umshwalense oshibhile. Ngibone ukuxutshwa lapho ibanga elibukeka ngendlela efanayo lisetshenziswe ngephutha.
Ezingxenyeni zesevisi ezibucayi, ikakhulukazi ukugqwala, ngokuvamile udinga okwengeziwe. Lokhu kungase kuhlanganise ukuhlolwa kokugqwala kwe-intergranular ngayinye ye-ASTM G28 Method A ye-HAZ yokushisela, noma ukuhlola okuqukethwe kwe-ferrite. Ukuhlolwa kwe-dayi noma ukuhlolwa kwe-radiographic kokusakazwa cishe kunikezwe. Izindleko zalezi zivivinyo zidinga ukubhakwa kusukela ekuqaleni; akuzona 'ezengeziwe'. Umphakeli ojwayele ukusebenza nalezi ama-alloys akhethekile izoba nalawa maphrothokholi okuhlola ekuhambeni kwawo okujwayelekile komsebenzi futhi ngeke iwaxake. Yabo iwebhusayithi ikhuluma ngezinto ezifana nalezi, okusho isistimu yekhwalithi eyakhelwe ukuzisingatha.
I-takeway yokugcina? I-N08825 iyinto emangalisayo uma isetshenziswe ngendlela efanele. Kodwa ukusebenza kwayo kuxhumene ngokungenakuhlukaniswa nobungcweti obusetshenziswa kuzo zonke izinyathelo-kusuka esithandweni somlilo kuya kusitembu sokugcina se-QC. Iklomelisa ubuchwepheshe futhi ijezisa izinqamuleli. Lowo umehluko wangempela phakathi kwengxenye esanda kwenziwa nge-Alloy 825 kanye nesebenza ngempela njengoba kufanele i-Alloy 825.
