Mukuwona Stellite 6 ikubwera papepala, ndipo lingaliro laposachedwa ndilolimba kwa ma valve ndi mipando. Kumeneko sikulakwa, koma kuli ngati kuyitana mpeni wa Asilikali a ku Switzerland kuti ndi mpeni. M'zaka zanga zozungulira zoyambira ndi masitolo ogulitsa makina, kuphweka kumeneku kwadzetsa zolakwika zingapo komanso kukanda mutu pambuyo poyika. Chowonadi ndi chakuti, Stellite 6 ndi aloyi ya cobalt-chromium-tungsten yomwe machitidwe ake amalumikizidwa kwambiri ndi momwe amapangidwira, kuponyedwa, kuwotcherera, kupangidwa ndi makina - komanso zomwe amaphatikizidwa. Si fumbi lamatsenga lomwe mumawaza pagawo kuti musagonjetsedwe nthawi yomweyo.
The Casting Conundrum: Fluidity vs. Integrity
Kuponya Stellite 6 ndipamene gawo loyamba la nuance likuwonekera. Mbiri yake ya castability yabwino imapezedwa, makamaka chifukwa cha madzimadzi abwinowo akasungunuka. Takhala tikugwira nawo ntchito zambiri zopangira zipolopolo komanso zopangira ndalama pamalo athu. Koma zabwino sizitanthauza kukhululuka. Makhalidwe akukula kwa kutentha ndi... makamaka. Ngati simusamala za kamangidwe ka zitseko zanu ndi kuziziritsa kuziziritsa, mukuitana misozi yotentha, makamaka muzojambula zamitundu yopyapyala. Si vuto la aloyi; ndi sayansi chabe yofuna ulemu.
Ndikukumbukira gulu la zopopera zomwe tidachita zaka zapitazo. Kusindikiza kunafuna Stellite 6 kuponyera masamba pa chitsulo chosapanga dzimbiri. Kuthamanga koyambirira kunali ndi chiwopsezo chokana pafupi ndi 30% chifukwa cha kung'ung'udza pang'ono pamphambano. Vuto silinali chemistry ya aloyi koma kuchepa kwa kusiyana pakukhazikika. Kukonzekera kunali kukonzanso dongosolo la chakudya cha nkhungu ndi tweak ku kutentha kusanayambe kutentha kwa chipolopolo cha ceramic. Zinawonjezera mtengo ndi nthawi, koma inali njira yokhayo yopezera kukhulupirika kwadongosolo. Ndiwo ntchito zobisika ndi ma aloyi apadera awa.
Apa ndi pamene zokumana nazo za foundry zimatiuza. Sitolo yomwe idangothiridwapo chitsulo chotuwa kapena chitsulo cha kaboni imatha kukhala bwino, koma kumveka kwamkati kumatha kusokonezedwa. Ku QSY, ndi zaka makumi atatu mu chipolopolo ndi kupanga ndalama, mumayamba kumva zinthu izi-kusakanikirana kwa deta kuchokera m'mbuyomu komanso kusintha kwachibadwa kwa magawo a ndondomeko pamtundu uliwonse watsopano. Sizimangotsanulira chitsulo A mu nkhungu B.
Machining: Choonadi Chokhumudwitsa
Ngati kuyiyika kumafuna finesse, kuikonza kumafuna kuleza mtima ndi zida zoyenera. Kuitana Stellite 6 zovuta makina ndi understatement. Sizovuta mofanana ndi chida cholimba chachitsulo; ndizovuta komanso zolimba ngati zopenga. Tengani chodulira chopepuka ndi choyikapo chosawoneka bwino, ndipo mwangopanga pamwamba molimba kuposa chodulira, kutsimikizira kulephera kwa chida pakadutsa lotsatira.
Taphunzira izi movutirapo pa ntchito yokonza makina a CNC pazigawo zina za ma valve. Zolembazo zidafuna kulolerana kolimba pankhope zokhalapo. Njira yathu yoyamba idagwiritsa ntchito magiredi wamba a carbide. Zinali zomvetsa chisoni—kuvala zida mopitirira muyeso, kusamalidwa bwino kwa pamwamba, ndi kugwedezeka. Njira yothetsera vutoli sinali nkhanza. Tinasinthira ku giredi yodzipatulira ya carbide yokhala ndi kukonzekera kwakuthwa m'mphepete komanso kuyika zida zolimba kwambiri. Ngakhale panthawiyo, kuthamanga ndi zakudya zinali zosasintha, ndipo tinavomereza kuti moyo wa zida udzakhala waufupi. Chofunikira ndikuwongolera kutentha ndikusunga mosasinthasintha, mwamadulidwe wokwanira kuti mulowe pansi pa gawo lolimba la ntchito.
Ichi ndi chowonadi chomwe sichimafika papepala la data. The chidwi chipinda-kutentha kuuma ndi kuvala kukana Stellite 6 kumasulira mwachindunji ku mtengo wokwera makina. Sitolo iliyonse yomwe imagwira ntchito iyenera kuganizira kugwiritsa ntchito zida komanso nthawi yocheperako. Ndi kusinthanitsa: ntchito yodabwitsa muntchito motsutsana ndi zopanga zodula kwambiri.
Dansi Yowotcherera: Kulowetsa Kutentha Ndi Chilichonse
Mwinamwake ntchito yofala kwambiri imakhala ngati nsonga za weld. Ndipo apa pali msampha waukulu kwambiri: kuchichita ngati chitsulo china chodzaza. Kuthekera kwa Stellite 6 kusweka ngati wowotcherera molakwika ndi nthano. Netiweki ya carbide yomwe imapatsa mawonekedwe ake kuvala imatha kukhala vuto ngati mutaya kutentha kwambiri muzitsulo zoyambira.
Taziwona pa ntchito zokonza zomangira za extruder. Sitolo imayesa kupanga ndege yomwe yawonongeka ndi Stellite 6 pogwiritsa ntchito njira yapamwamba kwambiri, yodutsa imodzi. Zotsatira zake nthawi zambiri zimakhala ming'alu yomwe imafalikira kuchokera kudera lomwe lakhudzidwa ndi kutentha kupita kumalo omwewo mkati mwa masabata a ntchito. Njira yolondola ndiyovuta kwambiri: kulowetsa kutentha pang'ono, nthawi zambiri kugwiritsa ntchito njira ngati Plasma Transferred Arc (PTA) kuwongolera bwino, zigawo zoonda zingapo, ndikuwongolera kutentha kwapakati. Nthawi zina, mungafunike wosanjikiza wopaka utoto wa nickel alloy musanagwiritse ntchito Stellite.
Ndi kuvina pakati pa dilution ndi diffusion. Mukufuna kuphatikizika kokwanira kuti mugwirizane, koma osati mochuluka kuti zinthu zachitsulo zoyambira zimachepetsera zokutira ndikuwononga katundu wake. Kukonza izi mosadukiza ndizomwe zimalekanitsa ntchito yoyenera ndi bomba lanthawi yanthawi. Si luso lomwe mumapeza usiku wonse.
Kuphatikizika Kwazinthu ndi Zochitika Padziko Lonse
Stellite 6 simagwira ntchito yokha. Kachitidwe kake ndi kogwirizana ndi zomwe zimatsutsana. Kukaniza kwake kolimba komanso zomatira kumapangitsa kuti ikhale yabwino kusankha kusindikiza nkhope mu mavavu - ganizirani mpando wa Stellite 6 motsutsana ndi pulagi ya Stellite 6. Koma m'malo abrasive slurry, monga kuchapa malasha kapena mapampu amigodi, ntchito yake imatha kukhala yodabwitsa modabwitsa.
Ndimakumbukira nkhani ina yokhudzana ndi mbale zovala zapampu zamatope. Wogula poyamba adatchula zonse Stellite 6 zokutira kutengera mavalidwe ake wamba. Muutumiki, zidayenda bwino, koma osati mochititsa chidwi, ndipo mtengo wake unali wokwera. The kulephera mode anali makamaka otsika-stress abrasion kuchokera zabwino, particles zolimba. Pambuyo pake tidapanga malingaliro ndikuyesa njira yophatikizika: yolimba kwambiri, yosamva kuphulika kwa ceramic masanjidwe ophatikizika a malo olowera mwachindunji, ndi Stellite 6 yogwiritsidwa ntchito mwanzeru m'malo omwe amakonda kukokoloka kwa cavitation ndi dzimbiri. Moyo wautumiki udayenda bwino kwambiri. Phunziro linali lakuti kuvala ndi banja la njira zolephera, ndipo palibe chinthu chimodzi, ngakhale Stellite, ndi mfumu ya zonse.
Izi zimafika pamtima pa uinjiniya wothandiza. Simungosankha zinthu kuchokera patebulo. Mukuyang'ana makina ovala, kutentha kwa ntchito, kukhalapo kwa dzimbiri, kupanikizika kwa dongosolo, ndi mtengo wa nthawi yopuma. Nthawi zina, Stellite 6 ndiye chisankho chabwino kwambiri. Nthawi zina, zimachulukirachulukira, kapena zofooka zake (monga kukana mphamvu) zimapangitsa kuti zikhale zosayenera. Wothandizira amene amamvetsetsa izi, monga QSY, yomwe imagwira ntchito pazitsulo zotayidwa, zitsulo, ndi ma aloyi apaderawa, akhoza kukhala ofunikira poyendetsa zisankhozi, osati kungosindikiza.
Pambuyo pa Hype: Chida chomwe chili mu Bokosi
Ndiye, chotengerako ndi chiyani mutawona zinthuzi m'njira zosiyanasiyana - monga zoponyedwa kuchokera munjira yathu yogulitsira, zomakina zamakina, zokutira zomata pamiyendo ikuluikulu? Stellite 6 ndi zida zaukadaulo zamtengo wapatali, koma si yankho lachilengedwe chonse. Phindu lake limatsegulidwa kokha ndi kuwongolera kolondola kwa njira komanso kumvetsetsa mozama za ma idiosyncrasies ake.
Makampani nthawi zina amagwera mumsampha wongotchula dzina lokha, ngati chithumwa kuti chikhale cholimba. Ndiyo njira yachidule yowopsa. Zofunikira zenizeni ziyenera kuphatikizapo malo ogwirira ntchito ndi njira yopangira. Aloyi ya Stellite 6 yopangidwa mwaluso imatha kukhala yocheperako chifukwa chosachita bwino poponya, makina ankhanza omwe amapangitsa kupsinjika kwapansi pamadzi, kapena kuwotcherera mosasamala komwe kumapangitsa malo oyambitsa ming'alu.
Pomaliza, zipangizo monga Stellite 6 kukukumbutsani kuti kupanga ndi sayansi yogwiritsidwa ntchito, osati buku lophika. Mapepala a deta kuchokera kwa opanga alloy amakupatsani mwayi. Ndizomwe zidasonkhanitsidwa, nthawi zina zovuta zopezako zoyambira ndi makina opangira makina - mtundu womwe unamangidwa zaka 30 pamalo ngati Qingdao Qiangsenyuan Technology - zomwe zimatanthawuza kuthekera kwake kukhala chinthu chodalirika, chochita bwino kwambiri chokhala mu mpope kapena valavu penapake, ikugwira ntchito yake mwakachetechete kwa zaka zambiri. Kumasulira kumeneko ndi luso lenileni.
