Mafotokozedwe Akatundu
Investment Casting, yomwe imadziwikanso kuti Lost Wax Casting, ndi njira yoponyera yolondola yomwe imapereka kusinthika kwapangidwe komanso phindu lalikulu lamtengo.
Njira ya Investment Casting imaphatikizapo kuthira zitsulo zosungunuka mu nkhungu yomwe yapangidwa pogwiritsa ntchito chitsanzo cha sera.Chikombolechi chikapangidwa, phula lakelo limasungunuka ndi kutha.Ma hollow cores amatha kuchitidwa pogwiritsa ntchito pachimake choteteza kutentha chomwe chimalepheretsa chitsulo chosungunuka kuti zisadzaze nkhungu.
Investment Casting nthawi zambiri imagwiritsidwa ntchito popanga zing'onozing'ono, koma imatha kugwiritsidwa ntchito kupanga zida zazikulu.
Kulekerera kwapang'onopang'ono kwa ± 0.003 in./in.zimatheka mosavuta.Ziwalo zofewa zokhala ndi makoma owonda ngati 0.025 in. zitha kupezedwa ndikuponya ndalama.
Common Material Maphunziro aKuponya Kwazitsulo Zosapanga dzimbiri
Chithunzi cha SS304:Chitsulo chogwiritsidwa ntchito kwambiri cha austenite, chikhoza kutchedwa A2 chosapanga dzimbiri.
Chithunzi cha SS316:Chitsulo chachiwiri chodziwika bwino cha austenite, chomwe chimatchedwanso A4 chosapanga dzimbiri.SS316 imagwiritsidwa ntchito makamaka pakuwonjezeka kwake kukana dzimbiri.
SS304L ndi SS316L(superaustenitic zitsulo zosapanga dzimbiri): The [L” zikutanthauza kuti mpweya wa aloyi ndi pansi pa 0.03%, zomwe zimachepetsa mphamvu yodziwitsidwa chifukwa cha kutentha kwakukulu komwe kumakhudzidwa ndi kuwotcherera.Yerekezerani ndi mndandanda wa 300, zikuwonetsa kukana bwino kupsinjika-kudzimbirira kusweka.
17-4 PH:Nthawi zambiri mvula imaumitsa chitsulo chosapanga dzimbiri cha martensitic, chomwe chimagwiritsa ntchito pafupifupi 17% chromium ndi 4% faifi tambala.
Pamwamba Mankhwala aKuponya Kwazitsulo Zosapanga dzimbiris
Kuwombera Kuwombera: Amagwiritsidwa ntchito pochotsa khungu lakuda la oxide pambuyo poponya zinthu zachitsulo chosapanga dzimbiri.
Pickling & Passivation Chithandizo: Pickling ndi mankhwala njira yothetsera zinyalala pamwamba monga oxide khungu, dzimbiri, mawanga kuwotcherera, etc.Ndipo passivation ndi njira yomwe imapanga chosanjikiza chatsopano cha chromium choteteza, motero kumapangitsa kuti ma anti-oxidation azitha zitsulo zosapanga dzimbiri.
Electropolishing: Amagwiritsidwa ntchito pochotsa tinthu tating'onoting'ono tating'ono ndikuwongolera kuwala kwazitsulo zosapanga dzimbiri.
Kupukuta pagalasi: Mtundu wa njira yopukuta pamwamba yomwe imatha kukwaniritsa malo osalala komanso owala ngati galasi lomaliza.
Kugwiritsa ntchito Stainless Steel Castings
Pazinthu zapadera zachitsulo chosapanga dzimbiri, zitsulo zosapanga dzimbiri zimaperekedwa kwa mafakitale osiyanasiyana, makamaka omwe ali m'malo ovuta.M'munsimu muli ntchito zazikulu zoponya zitsulo zosapanga dzimbiri
