Anthu ambiri akamva “zotayira phula zotayika” nthawi yomweyo amaganiza za serayo. Ndilo lingaliro lolakwika loyamba. Ndondomeko ya sera ndi poyambira chabe, scaffold yanthawi yochepa. Nkhani yeniyeni ya zinthu imayamba sera itapita. Ndi za slurry, stuko, zitsulo zomwe mumatsanulira, ngakhale mpweya wa ng'anjo yanu yoyaka moto. Kupeza chimodzi mwa izi molakwika kumatanthauza kusiyana pakati pa kutulutsa mawu ndi mulu wamtengo wapatali. Ndawona ma projekiti ambiri akulephera chifukwa wina adalamula ufa wa 'standard' wosaganizira kukula kwa matenthedwe a alloy kapena geometry ya gawolo.
Maziko: Zonse Zimayamba ndi Chipolopolo Chabwino
Tiye tikambirane za nkhungu. Chigoba cha ndalama si 'pulasitala' chabe. Pazinthu zambiri zaumisiri, makamaka ndi zotayira zosungunuka kwambiri, mukuchita ndi makina opangidwa ndi silika, omwe nthawi zambiri amaphatikiza silika kapena ufa wa zircon. Chomangira ndichofunikira - ethyl silicate kapena silika ya colloidal. Zomangira za silika za colloidal ndizofala kwambiri tsopano chifukwa cha kusasinthika kwawo, koma makina a ethyl silicate amatha kukupatsirani kutha kwa pamwamba pa ma geometries ena, ngakhale ali ovuta kuwagwira. Chosankha apa chikuwonetsa ndondomeko yanu yonse yowumitsa. Kuthamanga kwambiri, ndipo mumapeza ming'alu; pang'onopang'ono kwambiri, ndipo mzere wanu wopanga ugundika mpaka kuyima.
Ndikukumbukira gulu la masamba a nickel-based superalloy turbine omwe tidachita. Kusindikizaku kunafuna makoma owonda kwambiri. Tidagwiritsa ntchito slurry yathu ya zircon primary slurry, koma stucco inali yolakwika - mchenga unali wouma kwambiri. Izo sizinatsekeredwe bwino mu slurry m'mbali zabwinozo. Chotsatira? Kulowa kwachitsulo, malo owumbika ngati oponyedwa omwe adatenga zaka kuti makina ayeretsedwe. Phunziro linali lakuti zotayira phula zotayika pakuti chipolopolocho chiyenera kufananizidwa osati ndi chitsulo chokha, koma ndi kukula kwake. Kuti mumve zambiri, mumapita bwino kwambiri ndi chovala chanu kuyambira pamalaya oyamba, ngakhale zitatanthauza kuwonjezera malaya ena kapena awiri kuti mukhale wolimba.
Apa ndipamene zokumana nazo kuchokera ku shopu yanthawi yayitali zimafunikira. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka 30 zapitazo kuponya ndalama ndi makina, adzakhala ndi ma formula awo a slurry ndi ma stucco gradations kuti aziyitanira kwa mabanja osiyanasiyana. Sikuti akungogula 'ndalama'; amayang'anira laibulale yazinthu zophatikizira zitsulo zotayidwa motsutsana ndi cobalt-based alloys, mwachitsanzo. Chidziwitso chamagulu muzokonzekera zakuthupi ndizomwe mukulipira.
Sera Payokha: Sikuti Onse Amapangidwa Mofanana
Bwererani ku sera. Zikuwoneka zophweka, koma ndi kusakanikirana kolondola kwa polima. Muli ndi sera yanu yapatani, sera yanu yothamanga, ndi sera yanu yokonza. Ali ndi malo osungunuka osiyanasiyana, ma viscosities, ndi mitengo yocheperako. Kugwiritsira ntchito sera yochepetsera kusungunuka kwachitsulo pamtunda wosungunuka kwambiri kungayambitse kusokoneza pa msonkhano kapena kumayambiriro kwa kusungunuka. Mutu waukulu kwambiri ndikukulitsa sera. Sera yanu ikakula kwambiri pa kutentha kwina, imatha kuthyola chipolopolo chobiriwira chobiriwiracho panthawi ya autoclave dewaxing. Poof, nkhungu yanu ikupita.
Tinayamba kugwiritsa ntchito sera 'yotsika mtengo' kuti tipeze zitsulo zosapanga dzimbiri. Magawo a jekeseni wa sera anali otsika pang'ono, ndipo serayo inali ndi kutsika kwakukulu kwa volumetric. Zinkawoneka bwino mpaka titayamba kusonkhanitsa maguluwo - machitidwewo anali okhotakhota pang'ono, zomwe zimapangitsa kuti mizere yosagwirizana pamasewera omaliza. Zosungidwa pa sera zidachotsedwa kakhumi ndi NDT yowonjezera komanso makina ofunikira. Tsopano, timamatira ndi zosakanikirana zotsimikiziridwa ndikuyendetsa magulu ang'onoang'ono oyesa pulojekiti iliyonse yatsopano. Sera ndi ndondomeko yeniyeni; ngati ziri zolakwika, chirichonse chakunsi kwa mtsinje ndi cholakwika.
Kudzaza kwa Zitsulo: Kumene Sayansi Yazinthu Imakhala Yeniyeni
Ili ndi gawo lodziwikiratu, koma lodzaza ndi zobisika. Tsamba la deta la 316L lopanda banga ndi chinthu chimodzi; momwe kutentha kwachitsulo kumayendera ndi chipolopolo chanu chapadera pa kutentha kwanu kwapadera ndi china. Kusungunuka, chizolowezi chong'ambika, kufota - zonse zili mwatsatanetsatane. Ndi ma alloys apadera monga mindandanda ya nickel kapena cobalt QSY, kuwongolera kumakhala kolimba. Aloyi awa nthawi zambiri zotakasika. Ngati chipolopolo chanu chili ndi chemistry yolakwika kapena sichinasinthidwe mokwanira, mutha kupeza mawonekedwe oyipa omwe ndi ovuta kuwachotsa.
Gating ndi kudyetsa kapangidwe ndi mbali ya zotayira phula zotayika kukambirana, nawonso. Zokwera (nthawi zambiri aloyi yemweyo) ndi nsembe yowerengeka. Kukula kwake ndi kuyika kwake ndi ntchito ya gulu lolimba la alloy. Aloyi wautali amafunikira njira yodyetsera yosiyana ndi yochepa. Ndawonapo zipolopolo zokongola zikutsanulidwa bwino, kuti ndipeze shrinkage porosity pamalo okhuthala chifukwa chokweracho chinali cholakwika kapena chaching'ono kwambiri. Chitsulocho chinali 'chofotokozera', koma mapangidwe ake sankalemekeza katundu wake.
Wosewera Wosawoneka: The Burnout Cycle
Kaŵirikaŵiri kumanyalanyazidwa mu mndandanda wa zipangizo ndi mpweya wa ng'anjo. Kutopa kumagwira ntchito ziwiri zofunika kwambiri: kumachotsa sera (popanda kung'amba chipolopolo) ndikuyika chipolopolocho kukhala nkhungu yolimba komanso yosasunthika. Miyezo ya kutentha, kagwiridwe, ndi chilengedwe (mpweya, nayitrojeni) zonse ndi gawo la 'zinthu zakuthupi'. Njira yowopsa kwambiri imatha kuwomba zipolopolo popanda kuthamanga kwa nthunzi. Kutentha kosakwanira komaliza kumapangitsa kuti chipolopolocho chikhale chofooka komanso chosavuta kulowa mkati mwachitsulo.
Kwa ma cores ovuta kapena zosefera za ceramic mkati mwa nkhungu, kuzungulira kwanthawi zonse kumakhala kofunikira kwambiri. Izi ndi zida zosiyanasiyana za ceramic zomwe zili ndi ma curve awo okulitsa. Ngati sizikugwirizana ndi kukula kwa kutentha kwa chipolopolo chachikulu, mumapeza ming'alu. Ndi dongosolo. Simungangogula chipolopolo cha 'chabwino' ndi "zabwino" zapakati; muyenera kuonetsetsa kuti akugwira ntchito limodzi panthawi yonse yotentha. Ichi ndi chipika chapamwamba mu prototyping.
Kulephera Monga Mphunzitsi: Maganizo Olakwika
Kulephera kwanga kwambiri pamaphunziro kunali chigawo chathyathyathya, chofanana ndi mbale mu chitsulo cha ductile. Tinagwiritsa ntchito chipolopolo cha silika chosakanikirana. Gawolo linatuluka litawerama, ngati chipwirikiti cha mbatata. Zinthuzo zinali zabwino, chipolopolocho chinali cholimba. Nkhaniyo inali kuzizira kosiyana. Mphepete zopyapyalazo zinalimba ndi kuphatikana poyamba, kukoka pakati pa chivundikirocho, chomwe chinalimba ndi kupsinjika maganizo. Zida za chipolopolo palokha, ngakhale zinali zokanira, zinalibe kutulutsa koyenera kapena matenthedwe olimbikitsa kuziziritsa kofanana. Tidazithetsa posinthira ku chipolopolo chokhala ndi aluminiyamu yapamwamba kwambiri pantchitoyo, zomwe zidasintha mphamvu yochotsa kutentha, komanso powonjezera nthiti zoziziritsa kukhosi mupatani ya sera yomwe. Zinandiphunzitsa kuti nkhungu imagwira nawo ntchito yolimbitsa thupi, osati chidebe chokhazikika.
Kubweretsa Zonse Pamodzi: The Shop Floor Reality
Kotero pamene mukuyesa zotayira phula zotayika, simukutenga zinthu pashelefu. Mukupanga zinthu zomwe zimagwirizana, zokhazikika. Sera iyenera kugwira ntchito ndi zida zanu ndi kusonkhanitsa. Zipangizo za chipolopolo ziyenera kugwira ntchito ndi njira yanu yochotsera sera, kutentha kwachitsulo chanu, ndi mawonekedwe ake olimba. Chitsulocho chiyenera kukhala cha kalasi ndi khalidwe logwirizana ndi zovuta zomwe gawo likuwona. Pomaliza, ndondomeko yonseyi iyenera kukhala yokhazikika kuti ibwerezedwe, batch pambuyo pa mtanda.
Ichi ndichifukwa chake kugwirizana ndi odziwa zambiri foundry sikungokhudza outsourcing sitepe. Mukulowa muzozama zawo, zomwe nthawi zambiri zimapambana movutikira, zakuthupi ndi zopangira. Olimba ngati Mtengo wa QSY sikuti kumangogulitsa zinthu zojambulidwa; akugulitsa kugwiritsa ntchito koyenera kwa zaka makumi atatu za kuyanjana kwa zinthu - podziwa kuti ndi chipolopolo chiti chomwe chimapangitsa kuti pakhale mawonekedwe osinthika. ma aloyi apadera, kapena momwe mungasinthire kutentha kwa preheat kwa gawo lachitsulo chochepa kwambiri cha khoma. Zipangizo ndi zosakaniza, koma Chinsinsi chenicheni chili m'mabuku a sitolo ndi malingaliro a akatswiri. Mutha kugula ufa womwewo ndi sera zomwe amachita, koma popanda mawuwo, mukungoyembekezera zabwino. Mu masewerawa, chiyembekezo si njira.
