Thaum cov neeg feem coob hnov 'kev nqis peev casting alloy', lawv tam sim ntawd xav txog cov khoom siv-316 stainless, tej zaum 17-4PH. Qhov ntawd yog thawj qhov yuam kev. Lub alloy tsis yog cov khoom koj xaj; nws yog tag nrho tus cwj pwm profile los ntawm yaj mus rau tag. Kuv tau pom ntau cov duab kos qhia txog qib tus qauv yam tsis xav txog kev nthuav dav thermal thaum lub plhaub hlawv lossis yuav ua li cas ib qho nickel-based superalloy yuav ua rau lub zos ceramic slurry. Nws tsis yog kev yuav khoom. Nws yog kev sib tham ntawm chemistry, txheej txheem, thiab kev ua haujlwm kawg.
Cov Ntsiab Lus Tsis Txaus Siab: Nws Muaj Ntau Tshaj li Daim Ntawv Chemistry
Cia peb tau tshwj xeeb. Ib tus neeg siv khoom ib zaug tau hais kom siv qhov kev ua haujlwm siab peev casting alloy rau ib tug turbine hniav qauv, ib tug proprietary nickel-chromium mix. Daim ntawv qhia tshwj xeeb tau cog lus zoo kawg nkaus tawm lub zog ntawm 800 ° C. Qhov nws tsis tau hais tias nws tsis zam txim rau thaum lub sij hawm dewaxing. Peb siv cov txheej txheem chav autoclave voj voog. Qhov tshwm sim? Micro-cracks nyob rau hauv lub plhaub, yuav luag tsis pom, uas tsuas yog tshwm sim raws li qhov chaw tsis xws luag tom qab kawg kev kho cua sov. Cov hlau tsis yog qhov phem - peb cov txheej txheem tsis haum rau nws qhov tshwj xeeb solidification shrinkage thiab thermal shock resistance. Qhov ntawd yog zaj lus qhia: cov ntaub ntawv alloy yog tshooj ib. Tshooj ob yog sau rau hauv koj qhov chaw tsim khoom.
Qhov no yog qhov twg xyoo caum ntawm khw hauv pem teb kev paub trump phau ntawv kev paub. Tuam txhab uas muag kawg, xws li Qingdao Qiangsenyuan Technology (QSY), tsis yog muag castings; lawv muag qhov kev pab txhais lus no. Koj tuaj yeem pom nws ntawm lawv qhov chaw ntawm https://www.tsingtaocnc.com. Nrog ntau tshaj 30 xyoo hauv plhaub thiab peev casting, lawv tus nqi tsis yog nyob rau hauv pouring hlau; Nws yog nyob rau hauv kev paub tias cov cobalt-raws li alloy rau kev kho mob cog yuav tsum muaj qhov sib txawv ua ntej kub kub rau pwm dua li cov hlau tsis muaj steel rau cov khoom noj khoom haus.
