Xa usiva 'iplagi yeStellite', ingcinga ekhawulezileyo ihlala iqinile, indawo engagugiyo yevalve okanye impompo. Akulunganga oko, kodwa kukwenza lula oku kunokukhokelela kwiimpazamo ezichaziweyo. Ngokwenyani, libakala elithile, ingqibelelo yokuphosa, kunye nomatshini wasemva kokuchaza ngokwenene ukusebenza kwawo kwiindawo ezohlwayayo. Ndibone ukungaphumeleli okuninzi okulandelwa emva ekuphatheni zonke iinxalenye ze-alloy esekwe kwi-cobalt njengempahla etshintshayo.
I-Nuance yezinto eziphathekayo emva kweGama
IStellite asiyonto enye; lusapho lwecobalt-chromium alloys. Ukhetho phakathi, yithi, iStellite 6 kunye ne-Stellite 12 yeplagi ayinamkhethe. I-Stellite 6 ibonelela ngokugqwesileyo kokunxiba jikelele kunye nokumelana ne-cavitation, eyenze ukuba ibe yinto yethu yokusilela kwizicelo ezininzi zempompo ezinodaka. Nangona kunjalo, sasikhe saba nenkqubo yevalve yokubeka yodwa yobushushu obuphezulu apho umxhasi wanyanzelisa iStellite 6 ngokusekwe kusetyenziso 'jikelele' lwangaphambili. Isebenza ngaphantsi kokudinwa kwe-thermal. Ukutshintshela kwibakala eliphezulu lekhabhoni elifana ne-Stellite 12, elilinganisa ukuxhathisa ukunxiba kunye neempawu ezingcono ze-thermal, isombulule umba. Isifundo yayikukujonga ngaphaya kwegama le-brand kwindawo yokwenyani yenkonzo-ukhukuliseko, ubushushu, imidiya ye-corrosion, kunye nomthwalo wempembelelo zonke zizinto ezithatha isigqibo.
Kulapho ukusebenza kunye ne-Foundry eqonda i-metallurgy yinto engaxoxiswana. Awunakuvele uthumele umzobo kunye ne-callout yezinto eziphathekayo. Ingxoxo kufuneka igubungele umjikelo opheleleyo womsebenzi. Ndikhumbula iprojekthi kunye Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) apho besiphuhlisa iplagi yevalvu enkulu yomthengi wepetrochemical. I-spec yabiza i-alloy esekelwe kwi-nickel ekuqaleni, kodwa emva kokuqhawula idatha yenkonzo-ebandakanya iikhompawundi zesulfure kunye ne-cyclic shock shocks-iqela labo lobunjineli licebise ukuhluka kwe-alloy esekelwe kwi-cobalt ababenamava kuyo kwiimeko ezifanayo. Elo cebiso, elivela kumashumi amathathu eminyaka abo besenza ialloyi ezikhethekileyo, mhlawumbi lithintele ukusilela kwangaphambi kwexesha. Luhlobo lokuchazwa kwentsebenziswano olongeza ixabiso lokwenyani.
Inkqubo yokuphosa ngokwayo ibalulekile kwezi ngxubevange. Uyilo olulambathayo okanye uyilo lwesikhuphukeli lunokwazisa i-shrinkage porosity kanye kwindawo ebalulekileyo yokutywina okanye ukunxiba. Ndinqumle iiplagi ezivulekileyo ezaliwe kwaye ndafumana i-voids engabonakaliyo kumphezulu. Yiyo loo nto ulawulo lwenkqubo ye-Foundry, ngakumbi iqokobhe okanye utyalo-mali olufakwa kwezi alloys ezibizayo, kubaluleke kakhulu. Ayikokunyibilika nokugalela nje; imalunga nolawulo lokuqinisa.
Ukuchaneka koMatshini: Apho uYilo ludibana neNyaniso
I-As-cast Stellite inzima ngenkohlakalo kwaye iyaboyisa kumatshini. Ukufumana ukunyamezela kokugqibela kunye nokugqitywa komphezulu a Iplagi yeStellite kulapho iiprojekthi ezininzi zikhubeka. Awunakuwenza umatshini njengentsimbi. Ijiyometri yesixhobo esingalunganga, isantya, okanye isantya sokutya siya kutshisa nje izinto ezifakiweyo okanye, okubi ngakumbi, zenza iintanda ezincinci kumaleko womphezulu, zidale iindawo zokuqalisa ngokusilela.
Oku sakufunda kabuhlungu kwasekuqaleni. Ibhetshi yeeplagi ibifuna ukugqiba okuhle kakhulu kumphezulu otywiniweyo wokutywina. Iiparamitha zethu ezisemgangathweni ze-CNC zezinto ezinzima zikhokelela kwincoko kunye ne-subpar surface. Kwafuneka sivavanye amabakala akhethekileyo, abukhali abukhali kwaye sihlengahlengise kakhulu isantya kunye nokutya kwethu. Isisombululo sisoloko sibandakanya ukucotha, ukusikwa kwangabom kunye nokupholisa koxinzelelo oluphezulu ukulawula ubushushu. Obu buchule bokwenza oomatshini kungoko sihlala sisebenzisana nababoneleli abadibeneyo abanje nge-QSY, abaphatha zombini ukuphosa kunye CNC Machining endlwini. Iphelisa umdlalo onetyala phakathi kwe-caster kunye ne-machinist xa inxalenye ingaphumeleli-ingabanini bayo yonke inkqubo ukusuka kwintsimbi etyhidiweyo ukuya kwinxalenye egqityiweyo. Ukujonga uluhlu lwabo lwesakhono kwi https://www.tsingtaocnc.com ibonisa oludibaniso oluthe nkqo yinxalenye engundoqo yomnikelo wabo.
Omnye umngeni womatshini kukubamba indawo yokuphosa. Ngenxa yokuba ijometri yokugqibela ihlala intsonkothile, ukuyila izilungiso ezikhusela ukuphosa okungaqhelekanga ngaphandle kokuyigqwetha ngexesha lokusika ngokukrakra bubugcisa obufihlakeleyo. Yenye yezo nkcukacha zisebenzayo ozixabisayo kuphela emva kokulahla izinto ezimbalwa ezibiza imali eninzi.
Uhlalutyo lokungaphumeleli: Ziziphi iiplagi ezaphukileyo ezikufundisayo
Ukuhlola iindawo ezingaphumelelanga yeyona mfundo igqwesileyo. Omnye umxholo ophindaphindwayo ayikokusilela kwezinto, kodwa ukusilela koyilo. Umzekelo weklasikhi uchaza iplagi yeStellite epheleleyo kwinkqubo apho isihlalo sokukhwelana siyinto ethambileyo. Iplagi inokusinda kakuhle, kodwa iya kuba nenyongo kwaye itshabalalise isihlalo, ibangele ukuvuza. Ngamanye amaxesha, isisombululo esichanekileyo sisigqubuthelo seStellite okanye ufake kuphela kumhlaba obalulekileyo wokutywina, hayi yonke into.
Ndikhumbula imeko kwisixokelelwano samanzi somzi-mveliso wamandla. Iiplagi zazinxibe ngokulinganayo kodwa zisilele ekuhloleni ngokukhawuleza. Oyena nobangela ibingekokuxhathisa kweplagi; yayikukuba i-fine particulate emanzini yayizinziswa kwisitulo esithambileyo kancinane, ngokusijika sibe yintlama yokusila. Ukulungiswa kubandakanye ukuphonononga kwakhona yonke iperi yezinto eziphathekayo, kungekhona nje iplagi. Itshintshe incoko isuka kutshintsho olulula lwecandelo ukuya kuphononongo lokukhetha izinto ezikumgangatho wenkqubo.
Ukunxiba okuncediswa kukuhlwa ngomnye umbulali othuleyo. Iialloys ze-Stellite zinokuxhathisa okulungileyo kokutya, kodwa azingomlingo. Kwiimeko ezinciphisa kakhulu ezineasidi okanye iimeko ezinekloridi kumaqondo obushushu aphakamileyo, umaleko wechromium oxide ongenziwayo unokubekwa esichengeni. Ireyithi yokunxiba ke ikhawuleza kakhulu. Iplagi ehlala iminyaka kwinkonzo enye inokuhlala iinyanga kuphela kwenye ukuba ikhemistri yokubola ingahoywa.
ISigaba sokuHlanganisa kunye noVavanyo
Nokuba iplagi ephoswe ngoomatshini kunye nomatshini inokusilela kufakelo. Ukulingana nesitulo yiyo yonke into. Ngoku sinyanzelisa ukubopha iplagi kunye nesihlalo kunye njengeseti ehambelanayo yezicelo ezibalulekileyo. Le nto ayisoloko ikwi-spec, kodwa yi-inshurensi etshiphu. Inkqubo yokuqengqeleka idala ipateni yokutywina egqibeleleyo ebonwa ngumatshini we-CNC eyedwa ihlala ingenakufikelelwa.
Uvavanyo loxinzelelo yenye indawo yokwenyani. Iimvavanyo zokwamkelwa kwefektri (FAT) ngamanzi acocekileyo kwiqondo lobushushu le-ambient ziluncedo kodwa azimelanga ngokupheleleyo. Abayi kutyhila iingxaki ezinxulumene nokwandiswa kobushushu phakathi kweplagi kunye nomzimba wevalvu. Kwiinkonzo zobushushu obuphezulu, sityhala, okanye silinganisa, iimvavanyo zokusebenza ezishushu. Izikhewu zokucoca ezibalwe kwiqondo lokushisa kwegumbi zinokuvala okanye zivuleke phantsi kobushushu obusebenzayo, okukhokelela ekubopheni okanye ekuvuzeni.
Amaxwebhu avela kwi-Foundry yinxalenye yesi sigaba. Isatifikethi semathiriyeli esifanelekileyo (MTC) esilanda ubushushu bengxubevange, kunye neengxelo zokuhlolwa komgangatho kunye novavanyo olungonakalisi (njengokungena kwedayi kwiziphene zomphezulu), kunyanzelekile. Yipaspoti yecandelo. Ababoneleli abathembekileyo babonelela oku njengomgangatho. Yakha ukulandeleka kunye nokuzithemba.
Iingqwalasela zoQoqosho kunye noBonelelo
Masithethe inyani: Izinto zeStellite ziyabiza. Umxholo we-cobalt kunye ne-chromium ubonana neemarike zemveliso yehlabathi. Ithuku kukukhangela ibhidi ephantsi. Kodwa ngala macandelo, ixabiso lilonke lobunini kuphela kwemetric ebalulekileyo. Iplagi enexabiso eliphantsi esilela kwisiqingatha sexesha ixabisa ngaphezulu kakhulu ngexesha lokuphumla kunye nomsebenzi wokutshintsha kunentlawulo eyenziwe ngokuchanekileyo.
Apha kulapho ubudlelwane bexesha elide kunye nabanikezeli abanobuchule bobugcisa buhlawula khona. Baye baba lulwandiso lweqela lakho lobunjineli. Umzekelo, xa amatyathanga obonelelo lwehlabathi aqinisiwe kwiminyaka embalwa emva, ukuba netshaneli esekiweyo enomvelisi onobuchule onje ngeQSY, enengcambu zawo ezinzulu iqokobhe ngundo ukuphosa kwaye utyalo mali yee-alloys ezikhethekileyo, ukuqhubeka okuqinisekisiweyo. Banokucebisa ngamanye amabakala eemathiriyeli anentsebenzo efanayo kwisitokhwe esikhoyo ukugcina iprojekthi yolondolozo ebalulekileyo kwishedyuli.
Ekugqibeleni, ungalibali ixesha lokuhamba. Ukunyaniseka okuphezulu Iplagi yeStellite asiyonto ephuma kwishelufu. Phakathi komsebenzi wepateni, ukuphosa, unyango lobushushu, kunye nomatshini ochanekileyo, ishedyuli eyinyani ziiveki, hayi iintsuku. Ukungxamela nawaphi na kula manyathelo kukuthomalalisa ngokuthe ngqo umgangatho. Ukucwangcisa uluhlu lwakho lweempahla okanye iishedyuli zolondolozo malunga nale nyaniso yinxalenye yoqeqesho lobuchwephesha kunye nala macandelo awodwa.
