Raws li kev lag luam thoob ntiaj teb kev lag luam tsheb nrawm nrawm rau kev tsim qauv hnyav thiab kev ua haujlwm siab dua, aluminium casting tau dhau los ua cov txheej txheem tsim khoom tseem ceeb. Ntawm cov ntaub ntawv txhawb kev hloov pauv no,Aluminium titanate ceramic (Al₂TiO₅)ua lub luag haujlwm tseem ceeb ntxiv - tshwj xeeb hauvTsis tshua muaj siab tuag casting (LPDC)tshuab.
Los ntawm cov hlab riser mus rau cov khoom siv tiv thaiv thermocouple, aluminium titanate tau lees paub dav rau nws qhov tshwj xeeb thermal stability hauv kev xav tau qhov chaw casting.
Vim li cas Automotive Casting Yuav Tsum TauAdvanced Ceramics
Niaj hnub nimno automotive casting yuav tsum ua raws li cov cai nruj:
Lub teeb aluminium qauv
Nyias-phab ntsa geometry
Siab qhov tseeb
Tsawg porosity tus nqi
ruaj khov ntau lawm
Hauv LPDC thiab lwm cov txheej txheem tuag casting, molten aluminium yog thauj los ntawm aceramic riser tubeua ntej nkag mus rau hauv pwm. Cov khoom no yuav tsum zam:
Nruam raug rau molten hlau
Kev hloov pauv ceev ceev
Siab cycling
Ntev ntau lawm khiav
Ib txwm cam khwb cia hlau raj feem ntau raug kev txom nyem los ntawm oxidation thiab thermal qaug zog. Advancedtechnical cov ntaub ntawv ceramicxws li aluminium titanate muab kev ruaj khov dua.
Dab tsi ua Aluminium Titanate haum rau LPDC?
Tsawg heev Thermal Expansion
Ib qho tseem ceeb tshaj plaws ntawm txhuas titanate cov khoom yog nws nyob ze -zero thermal expansion cwj pwm.
Qhov no tso cai rau ib tugaluminium titanate riser rajkom tiv taus cua sov thiab cua txias kom tsis txhob tawg. Hauv tsheb LPDC cov kab ntau lawm - qhov twg thermal fluctuation yog tas li - cov cuab yeej no txhim kho kev ua haujlwm ruaj khov.
Zoo Tshaj Thermal Shock Resistance
Automotive casting feem ntau muaj feem ntau pib- nres cycles. Cov khoom uas tsis zoo thermal shock kuj tuaj yeem tawg nyob rau hauv qhov kub hloov pauv sai.
Al₂TiO₅ ceramic tuav cov txheej txheem kev ncaj ncees txawm tias nyob rau hauv qhov kev hloov pauv ntawm qhov kub thiab txias, ua rau nws muaj kev txhim khu kev qha rau:
Aluminium titanate riser raj
Ceramic stalk tubes
Thermocouple tiv thaiv tubes
Zoo Corrosion Resistance rau Molten Aluminium
Txawm hais tias silicon nitride ceramic muab superior corrosion kuj, aluminium titanate ceramic tseem ua tau zoo nyob rau hauv molten aluminium ib puag ncig.
Rau ntau qhov nruab nrab - mus rau siab - ntim automotive casting nroj tsuag, aluminium titanate muaj kev sib npaug ntawm kev ua haujlwm thiab tus nqi.
Daim ntawv thov ntawm Aluminium Titanate hauv Automotive Foundries
Nyob rau hauv automotive casting chaw, txhuas titanate Cheebtsam yog feem ntau siv nyob rau hauv:
Tsawg siab tuag casting riser raj tshuab
Aluminium log casting ntau lawm kab
Aluminium qhov chaw casting
Rauv kub tiv thaiv systems
Kev ruaj ntseg ntawm cov raj ceramic ncaj qha cuam tshuam rau:
Melt kev huv
Flow sib xws
Casting tawm los
Cov khoom siv downtime
Los ntawm kev kho dua tshiab rau aluminium titanate riser hlab, ntau cov foundries qhia txog kev txhim kho cov txheej txheem kev ntseeg siab thiab txo qis txij nkawm.
Aluminium Titanate vs Lwm Cov Khoom Siv Ceramic
Thaum xaiv cov khoom siv ceramic rau LPDC, cov chaw tsim khoom feem ntau sib piv:
Silicon nitride riser raj
Aluminium titanate riser raj
Nitride-bonded silicon carbide raj
Txhua yam khoom muaj nws qhov chaw engineering:
Silicon nitride ceramic- lub zog siab tshaj plaws thiab lub neej ua haujlwm ntev tshaj plaws
Aluminium titanate ceramic- qhov zoo tshaj plaws thermal shock kuj
NSI Ceramic - tus nqi- kev ua haujlwm sib npaug
Rau kev ua haujlwm hauv tsheb ua haujlwm uas ua kom muaj kev ruaj ntseg thermal thiab kev tswj hwm tus nqi, aluminium titanate tseem yog qhov kev xaiv zoo heev.
Kev Lag Luam Txhim Kho Kev Lag Luam Hauv Automotive Casting
Raws li EV ntau lawm nthuav dav thiab lub teeb yuag automotive Cheebtsam tau dhau los ua tus qauv, cov kev xav tau zoo yuav tsum tau nce ntxiv.
Automotive manufacturers tam sim no xav tau:
Tsawg tus nqi suav nrog
Cov qauv kev ntseeg siab dua
ruaj khov LPDC kev ua tau zoo
Predictable txij nkawm cycles
Raws li cov xwm txheej no, cov kav dej ceramic siab siab - suav nrog txhuas titanate - tau hloov cov tshuaj hlau ib txwm siv thoob plaws ntiaj teb cov chaw tsim khoom.
Cov khoom siv kho dua tshiab no tsis yog xaiv tau lawm; nws yog ib feem ntawm qhov dav dua modernization ntawm tuag casting tshuab.
Xaus
Aluminium titanate ceramic tau dhau los ua cov khoom tseem ceeb hauv kev siv tsheb niaj hnub no.
Nws qhov tshwj xeeb ua ke ntawm cov thermal expansion, muaj zog thermal poob siab, thiab kev ua haujlwm ruaj khov hauv molten aluminium ib puag ncig ua rau nws tsim tshwj xeeb rau LPDC riser raj tshuab.
Raws li kev lag luam tsheb txuas ntxiv hloov mus rau cov khoom siv hluav taws xob sib sib zog nqus, aluminium titanate yuav nyob twj ywm ib qho tseem ceeb ntawm cov ceramics txhawb kev ua haujlwm zoo, ruaj khov, thiab ntev - tswj cov nqi.
