Preface: Tam sim no, hauv kev lag luam tsheb hauv cov ntsiab lus ntawm kev siv hluav taws xob, kev txawj ntse thiab cov khoom siv tsheb hloov khoom dua tshiab, cov kev xav tau ntawm cov nres nres tau maj mam nce, thiab carbon ceramic nres discs muaj qhov zoo dua, tsab xov xwm no yuav tham txog carbon ceramic nres disc. kev lag luam.
I. Txheej xwm Background
Tsis ntev los no, Azera tau tshaj tawm nws thawj zaug loj tsib-lub rooj SUV, ES7, uas siv ib qho kev sib xyaw ua ke tag nrho-aluminium rear thav duab, qhov thib ob lub sij hawm Azera siv cov tshuab tuag-casting hauv nws cov khoom.Nrog rau txoj kev loj hlob ntawm lub teeb yuag thiab hluav taws xob, kev sib koom ua ke tuag-casting thev naus laus zis tau nrhiav tom qab los ntawm cov tuam txhab tsheb tshiab thiab cov tuam txhab tsheb tsoos, thiab lub teeb yuag ntawm cov qauv tsheb tau tsis ntseeg los ua ib feem tseem ceeb ntawm kev tsim kho tsheb niaj hnub no.Daim ntawv thov ntawm cov pa roj carbon ceramic nres discs yuav txhawb nqa cov txheej txheem ntawm kev siv tsheb sib tsoo, cov hauv qab no yog tham txog kev lag luam no.
Ob, nkag siab carbon ceramic nres discs
Tam sim no, cov khoom siv nres tau siv dav hauv cov tsheb ciav hlau ceev, tsheb thiab dav hlau yog cov hmoov hlau metallurgy thiab cov khoom siv carbon-carbon.Txawm li cas los xij, hmoov metallurgy nres cov ntaub ntawv muaj qhov tsis zoo xws li kev kub siab yooj yim kev sib txuas, kev sib txhuam kev ua haujlwm yooj yim poob qis, kub kub lub zog poob qis, tsis zoo thermal poob siab, kev pab lub neej luv, thiab lwm yam.thaum cov pa roj carbon nres cov ntaub ntawv muaj qhov tsis zoo li qub thiab ntub lub xeev kev sib txhuam coefficient, loj ntim ntawm cov cua sov cia, ntev ntau lawm voj voog thiab cov nqi ntau lawm, uas txwv tsis pub nws ntxiv kev txhim kho thiab daim ntawv thov.
Carbon ceramic nres discs muab cov khoom siv lub cev ntawm ob qho tib si carbon fiber thiab polycrystalline silicon carbide.Meanwhile, lub teeb yuag, zoo hardness, stability nyob rau hauv lub siab thiab kub, thermal poob siab kuj thiab shear puas tus yam ntxwv ntawm tib lub toughness tsis tsuas yog ncua lub neej kev pab cuam ntawm lub nres disc, tab sis kuj zam tag nrho cov teeb meem tshwm sim los ntawm lub load.
Thib peb, qhov xwm txheej tam sim no ntawm kev lag luam
1. Cov pa roj carbon ceramic nres disc kev ua tau zoo yog qhov zoo dua li qub grey cam khwb cia hlau nres disc, tab sis tus nqi yog nws qhov tsis txaus.
Tam sim no, cov khoom siv nres disc siv dav siv feem ntau yog cov hlau cam khwb cia hlau, cov hlau tsis tshua muaj hlau, cov hlau cam khwb cia hlau, tshwj xeeb alloy cam khwb cia hlau, qis alloy forged steel thiab cam khwb cia hlau cam khwb cia hlau (forged steel) cov ntaub ntawv sib xyaw, cam khwb cia hlau. cov ntaub ntawv yog siv dav dua.Cov ntaub ntawv hlau cam khwb cia muaj lub voj voog tsim khoom ntev, tsis zoo thermal conductivity thiab yooj yim los tsim thermal tawg thiab lwm yam tsis zoo, yog li cov khoom siv carbon thiab carbon ceramic sib xyaw rau kev tsim cov khoom siv nres.
Vim yog cov khoom siv carbon-carbon composite siab, feem ntau yog siv rau lub dav hlau nres, nrog rau kev loj hlob ntawm kev kub ceev tsheb ciav hlau nyob rau hauv xyoo tas los no, cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau pib tsim kev loj hlob ntawm high-speed railroads rau carbon ceramic composite kev sib txhuam. , carbon ceramic composite cov ntaub ntawv yog lub thoob ntiaj teb tsom rau txoj kev loj hlob ntawm kev sib txhuam cov ntaub ntawv, Tuam Tshoj kuj tau nyob rau hauv thawj theem, carbon ceramic nres discs nyob rau hauv lub neej yav tom ntej kom txo tau tus nqi ntawm qhov chaw yog loj, yuav tsum yog lub ntsiab kev loj hlob ntawm nres. cov khoom Nws xav tias yuav dhau los ua kev loj hlob tseem ceeb ntawm cov khoom lag luam nres.
2. Cov khoom siv ncaj qha ntawm cov pa roj carbon ceramic nres disc yog qhov tsawg, thiab muaj qhov chaw loj rau kev txo nqi ntawm kev siv tshuab thiab nplai.
Xyoo 2021, tus nqi ib tuj ntawm lub tuam txhab cov khoom lag luam kub yog 370,000 yuan / ton, nqis 20% los ntawm 460,000 yuan / ton hauv 2017, thiab tus nqi tsim khoom ib tuj yog 11.4 lab yuan hauv 2021, nqis 53.8% los ntawm 246,800 yuan hauv 2017, uas yog ib qho tseem ceeb ntawm kev txo nqi.Hauv 2021, tus nqi raw khoom tus nqi piv yog 52%.Nrog rau kev nthuav dav ntawm nplai, kev hloov kho thev naus laus zis, kev txhim kho qib automation thiab carbon fiber nqi poob, muaj qhov chaw loj heev rau cov khoom lag luam txo nqi.Tam sim no carbon ceramic nres ncoo ib daim nqi yog kwv yees li 2500-3500 yuan, rau nrog C chav kawm ntawv thiab saum toj no neeg caij tsheb lag luam, nws xav tias nyob rau hauv 2025 ib daim nqi yuav tsum poob mus txog 1000-1200 yuan, yuav poob. mus rau chav kawm B thiab siab dua cov neeg caij tsheb lag luam.
Plaub, kev lag luam zeem muag
1. Carbon ceramic nres discs muaj ntau qhov chaw rau kev hloov hauv tsev
Vim muaj qhov nyuaj ntawm cov txheej txheem, qhov nyuaj ntawm kev tsim khoom, lub voj voog ntev thiab lwm yam pib, cov lag luam hauv tsev uas tuaj yeem tsim cov pa roj carbon ceramic discs yog tsawg.Cov chaw muag khoom tseem ceeb ntawm carbon ceramic composite brake discs suav nrog Brembo (Ltalis), Surface Transforms Plc (UK), Fusionbrakes (USA), thiab lwm yam. Ob peb lub tuam txhab hauv tebchaws tau paub txog kev npaj cov tshuab ua haujlwm siab ntawm carbon / tau composite brake discs, thiab muaj. yog qhov chaw loj rau kev hloov pauv hauv tsev.
Cov neeg muas zaub tseem ceeb ntawm txawv teb chaws carbon ceramic nres disc manufacturers yog high-end kev ua si tsheb manufacturers, thiab chav tsev nqi ntawm cov khoom yog siab dua.Siv lub tuam txhab txawv teb chaws Brembo ua piv txwv, cov khoom lag luam tus nqi ntawm ib qho carbon ceramic disc yog ntau dua 100,000 RMB, thaum tus nqi ntawm ib qho khoom siv hluav taws xob hauv tsev yog li 0.8-12,000 RMB, uas muaj tus nqi siab heev.Nrog rau kev siv thev naus laus zis tsis tu ncua ntawm kev lag luam hauv teb chaws hauv daim teb no, thiab kev hloov pauv tas mus li ntawm "ntxiv, siab, ntse" tsheb tshiab lub zog, kev nkag mus ntawm carbon ceramic discs rau cov tsheb tshiab hauv tsev yuav tsum tau nce ntxiv.
2. Cov pa roj carbon ceramic nres discs ua tau raws li qhov sib txawv ntawm lub tsheb sib tsoo
Kev sim ua pov thawj qhia tau hais tias qhov txo qis ntawm 10% ntawm lub tsheb hnyav tuaj yeem ua rau kom muaj roj ntau dua 6% -8%;rau txhua txhua 100 kg txo nyob rau hauv lub tsheb loj, roj noj yuav txo tau los ntawm 0.3 - -0.6 litres ib 100 km, yog li lub teeb yuag technology yog qhov tseem ceeb txoj kev loj hlob kev taw qhia rau yav tom ntej tsheb.
Txo cov huab hwm coj hauv qab lub kaw lus ncua nrog ib nrab ntawm kev siv zog, carbon ceramic nres disc yog qhov tseem ceeb ntawm kev txo qhov hnyav.Txhua 1kg txo qis hauv qab lub kaw lus raug ncua yog sib npaug rau 5kg txo qis dua qhov kev ncua kev kawm.Ib khub ntawm 380mm loj carbon ceramic discs yog hais txog 20kg sib dua li grey cam khwb cia hlau discs, uas yog sib npaug rau 100kg qhov hnyav txo nyob rau hauv lub ncua kev kawm ntawv ntawm lub tsheb.Tsis tas li ntawd, Toyota lub high-end kev ua si tsheb Lexus RCF tau dhau los ntawm cov khoom siv CFRP thiab carbon ceramic nres discs kom txo qhov hnyav ntawm 70kg hauv ntau yam, ntawm 22kg yog pab los ntawm carbon ceramic nres discs, yog li carbon ceramic nres discs rau lub qhov tseem ceeb ntawm lub tsheb qhov hnyav txo.
V. Chaw Ua Lag Luam
Hloov cov hmoov hlau metallurgy nres disc yog qhov tseem ceeb ntawm qhov kev lag luam no: ua ntej, tus nqi ntawm cov roj carbon fiber yuav maj mam poob qis los tsav tus nqi ncaj qha ntawm cov khoom nws tus kheej;thib ob, nrog rau qhov nce ntawm cov khoom lag luam thiab kev muag khoom, kev ua kom zoo ntawm cov txheej txheem txuas, kev lag luam ntawm nplai yuav txo qis tus nqi ntawm carbon ceramic nres disc;thib peb, kev tsav tsheb nyab xeeb yuav txhawb kev txhim kho cov khoom hauv kev lag luam tsheb.2023 yuav tsum yog thawj xyoo ntawm carbon ceramic nres disc nce qib.Thawj xyoo ntawm kev nce qib ntawm nres disc, kev lag luam hauv tsev yuav tsum ncav cuag 7.8 billion yuan hauv 2025, thiab kev lag luam hauv tsev yuav tsum tshaj 20 billion yuan hauv 2030.
Los ntawm 2025, kev lag luam loj ntawm cov tsoos hmoov metallurgy nres discs yuav yog 90 billion yuan raws li tus nqi ntawm 1000 yuan rau ib lub tsheb thiab 90 lab tsheb muag thoob ntiaj teb, thiab kev lag luam hauv tsev yuav ze li 30 billion yuan.Nrog rau kev nrawm ntawm hluav taws xob, qhov nkag mus ntawm carbon ceramic nres discs yuav zoo li peb qhov kev cia siab.Qhov no yog lub lag luam tshiab uas haum rau cov qauv dav dav ntawm kev txawj ntse hluav taws xob thiab yog qhov kev sib tw ntawm 0-1.Thiab rau kev txiav txim siab txog kev nyab xeeb ntawm tsheb, ib zaug qhov kev tawg yuav dhau los ua qhov muag rau kev nyab xeeb tsheb, kev txhim kho tus nqi yuav tsum siab tshaj qhov kev cia siab, thiab yav tom ntej tag nrho cov nyiaj tau los ntawm kev muag khoom yuav tsum mus txog 200-300 billion yuan.
