Mafakitale a Stellite 12 amafunikira zambiri kuposa kuponyera kapena kupanga makina - amafunikira kuwongolera zitsulo, kutsimikizika kwapang'onopang'ono, komanso magwiridwe antchito otsimikizika. Pamene ma hydraulic pump nozzles amalephera pa bar 300, nyumba za pistoni zimavala pambuyo pa maola 8,000 ogwirira ntchito, kapena mipando ya valve ikaphwanyidwa pansi pa slurry slurry, chifukwa chake sichimapangidwa kawirikawiri - ndi kusasinthasintha kwa zinthu, kuwongolera madera okhudzidwa ndi kutentha, ndi kukhulupirika kwa microstructural. Apa ndipamene fakitale yowona ya Stellite 12 imadzilekanitsa yokha kuchokera kuzinthu zoyambira.
Chifukwa chiyani Stellite 12 Sikuti Ndi "Hard Alloy"
Stellite 12 (AMS 5387) sinasankhidwe kuuma kokha. Mtengo wake umakhala mu synergy ya cobalt-chromium-carbon matrix, ophatikizidwa ndi tungsten carbide particles, ndi mawonekedwe oyendetsedwa a eutectic-amapereka kukana kwa galling, kukokoloka kwa cavitation, ndi kutentha kwambiri kwa okosijeni mpaka 500 ° C. Koma magwiridwe antchitowo amangotuluka ngati kuchuluka kwamphamvu, kugawikana kwa interdendritic, ndi mbiri yakutentha kwapambuyo kumayendetsedwa mwamphamvu. Tawonapo magawo akukanidwa osati chifukwa cha kupatuka kwa mankhwala - koma chifukwa kuziziritsa kwanuko kudapanga madera okhala ndi chromium pafupi ndi makoma a nkhungu. Ichi ndichifukwa chake fakitale yathu ya Stellite 12 imayendetsa mizere ya ng'anjo yodzipatulira yokhala ndi nkhungu za ceramic zotenthetsera kale, magawo enieni a thermocouple m'magawo ofunikira, komanso mamapu ofunikira ang'onoang'ono pamagawo am'mbali-osati kungowerenga pamwamba.
Kuchokera Kutsanulira mpaka Kulondola: Ubwino Wophatikizira Woyimira
Otsatsa ambiri amatulutsa kunja mwina kuponyera kapena kupanga makina. Fakitale ya Stellite 12 yopangira zida zofunika kwambiri sichita chilichonse. Pamalo athu a Qingdao, ma aloyi a cobalt amalowa khomo limodzi - ndikumaliza mapulagi a AMS 5387, mipando ya ma valve opanikizika, kapena zodzigudubuza za winch center shaft kutuluka kwina. Izi zimachotsa mipata ya mawonekedwe: palibe kulumikizana molakwika pamazenera ochizira kutentha, palibe kutsetsereka kwapakati pakati pa malo opangira makina ndi makina, palibe kusweka kwapakati pakati pa batch yosungunuka ndi lipoti lomaliza la CMM. Mwachindunji, timakhala ndi ulamuliro pa magawo atatu omwe sitingakambirane:
- Kuponyedwa kwa Solidification Kuwongolera: Zopangira ndalama zophikidwa kale mpaka 1,100 ° C; kuthira kutentha komwe kumachitika mkati mwa ± 5 ° C; Kukhazikika kokhazikika kumayendetsedwa ndi mbale zoziziritsa kukhosi pansi pa malo ovala kwambiri
- Makina Ochepetsa Kupsinjika: Mabala onse aukali achitika musanatseke njira yothetsera; mapeto amadutsa pokhapokha atapumula kupsinjika pa 950 ° C / 4hr / argon atmosphere
- Functional Surface Integrity: Palibe "monga-makina" zomwe zimatsirizika pamalo osindikizira - timayika molunjika ku Ra ≤0.2 μm ndikutsimikizira mawonekedwe olumikizirana ndi utoto wabuluu wokhazikika potengera katundu
Izi sizongoyerekeza. Chida chimodzi chakumalo opangira mafuta ku North America OEM idachepetsa mavavu osakonzekera ndi 63% atasintha kuchoka pagulu lazinthu zambiri kupita ku fakitale yathu ya Stellite 12.
Zimene Makasitomala Amafunsa—Ndi Zomwe Sanena Mokweza
"Kodi mungafanane ndi gawo lathu lomwe lilipo?" Inde, ngati zojambula zanu zikuphatikiza ma callout a GD&T, osati milingo chabe. Koma zomwe akutanthauza ndi: *Kodi izi zikwanira popanda kukonzanso nyumbayo? Kodi idzasindikiza pa kukakamiza koyambira? Kodi idzapulumuka kwa miyezi 12 ikugwira ntchito ya gasi wowawasa?* Mafunso amenewo amayankhidwa kale kwambiri asanadule koyamba. Mainjiniya athu nthawi zambiri amawonetsa zoopsa zomwe zingapangidwe msanga: kulolerana kwa 0.05 mm pampando wa 120 mm m'mimba mwake wa Stellite 12 sikutheka - ndi yosakhazikika pokhapokha titatchula makulidwe ochepera a khoma, kuletsa kuchuluka kwa kusintha kwa gawo, ndi kulamula pambuyo popanga makina owunika akupanga. Sitigulitsa magawo. Timapereka kukonzekera kogwira ntchito.
Ena angatsutse kuti ma alloys a cobalt a pashelufu amapereka nthawi zotsogola mwachangu. Komabe, zenera lopapatiza la Stellite 12 limatanthauza "mwachangu" nthawi zambiri limafanana ndi "kukonzanso." Tatsata 41% zokolola zopambana koyamba pazithunzi zovuta kwambiri makasitomala akamatigwirizanitsa panthawi yachisanu - osati potengera kugula.
Kutsatiridwa komwe Mungathe Kutsimikizira-Osati Kungonena
Chigawo chilichonse cha Stellite 12 chimakhala ndi cholembera cha QR chomwe chimalumikizana ndi mapasa ake adijito: chipika chosungunuka (nambala ya kutentha, kusanthula kwazithunzi), lipoti loponyera (ID ya nkhungu, chithunzithunzi chozizira), mbiri yamakina (mtundu wa pulogalamu ya CNC, zowerengera za zida), ndi data yomaliza yoyendera (mitambo ya CMM, kuuma kozungulira). Palibe chidule. Palibe ma avareji. Manambala aiwisi-chifukwa kukana kwa dzimbiri kumadalira zomwe zili ndi chromium pamwamba, osati muzambiri zambiri. Timasunga kutsata kwathunthu kwa zaka 15, pa API Q1 ndi ISO 9001: 2015 zofunika. Ngati kasitomala anena kuti wavala msanga, timakoka zenizeni, kutengera zomwe zidalephera muzitsulo zathu zoyeserera, ndikuwunikira zomwe zidayambitsa - osati zifukwa.
Kuyang'ana m'tsogolo, fakitale yathu ya Stellite 12 ikukulitsa luso lopangira makina osakanizidwa a AMS 5387/T800 panjira zophatikizika zamadzimadzi-kuchotsa zolumikizira zowotcherera m'malo opanikizika kwambiri. Osati chifukwa ndi zachilendo, koma chifukwa deta yam'munda ikuwonetsa 78% ya kutayikira kumachokera pamawonekedwe azitsulo. Ndiko kusiyana pakati pa kupanga magawo a Stellite 12-ndi kuthetsa mavuto a Stellite 12.
