Ⅰ Core daim ntawv thov thaj chaw ntawm cam khwb cia txhuas alloys
Casting aluminium alloy tau dhau los ua cov khoom tseem ceeb hauv kev lag luam niaj hnub vim nws lub zog qis, muaj lub zog tshwj xeeb, thiab corrosion tsis kam. Nws daim ntawv thov teb tuaj yeem muab sau ua tsib nqe lus hauv qab no:
1. Kev thauj mus los: cov tub ntxhais thauj khoom ntawm lub teeb yuag kiv puag ncig
Automotive kev lag luam: Raws li qhov loj tshaj plaws downstream lag luam rau cam khwb cia txhuas alloys (sau tshaj 60%), nws yog dav siv nyob rau hauv lub cav lub tog raj kheej blocks, kis vaj tse, log hubs, thiab chassis structural Cheebtsam. Noj ADC12 alloy ua piv txwv, qhov nkag mus ntawm nws qhov tuag-casting qhov chaw nyob rau hauv lub zog tshiab lub tsheb roj teeb pob plhaub, lub kaus mom kawg, thiab lwm yam khoom siv txuas ntxiv mus ntxiv, thawb cov txhuas noj ib lub tsheb mus rau lub hom phiaj ntawm 220kg.
Aerospace: Hauv cov khoom siv dav hlau (xws li tis kab teeb, tsaws iav brackets) thiab lub cav qhov chaw (xws li turbine blades, casings), muaj zog aluminium alloys (xws li ZL205A) ua tiav qhov sib npaug ntawm qhov kub thiab txias tsis kam ntawm 400 ℃ thiab qaug zog tiv thaiv los ntawm T7 cov txheej txheem kho cua sov, ua kom cov roj efficiency zoo dua.
Txoj kev tsheb ciav hlau: Cov khoom tseem ceeb xws li kev kub ceev tsheb ciav hlau bogies thiab gearboxes yog ua los ntawm ZL1101A alloy, ua tiav qhov hnyav ntawm ntau dua 30% thaum ua kom muaj zog.
2. Hluav taws xob thiab hluav taws xob teb: kev txhawb nqa kev tsim khoom precision
3C cov khoom siv hluav taws xob: Qhov nruab nrab ntawm cov xov tooj smartphones thiab lub plhaub ntawm lub laptop yog ua los ntawm ultra-nyias aluminium alloy tuag-casting qhov chaw, thiab ZL402 alloy yog precision tsim nrog phab ntsa thickness ntawm 0.5mm los ntawm semi-khoom tsim technology, thaum ua tau raws li qhov yuav tsum tau ntawm electromagnetic shielding thiab tshav kub dissipation.
Cov cuab yeej siv hluav taws xob: ZL303 alloy yog siv rau lub plhaub ntawm high-voltage switchgear thiab transformer heat sink, uas nthuav tawm cov txiaj ntsig tshwj xeeb hauv kev tsim kho cov chaw nres tsheb hauv ntug dej vim nws cov dej hiav txwv corrosion kuj.
3. Mechanical khoom teb: ib qho kev ua qauv ntawm hnav thiab corrosion kuj
Cov neeg hlau muaj: Cov vaj tsev sib koom ua ke yog ua los ntawm eutectic Al Si alloy (xws li ZL117), thiab cov tshuab silicon theem spheroidization txhim kho hnav tsis kam los ntawm 40%, ncua kev pab cuam lub neej ntawm cov khoom siv.
Kev tsim kho tshuab: ZL104 alloy raug xaiv rau hydraulic twj tso kua mis lub cev, valve kob puag thiab lwm yam khoom, thiab ua tiav nrog T6 kev kho cua sov kom ua tiav σ b ≥ 350MPa, haum rau cov khoom siv siab.
4. Kev xyaum tshiab ntawm kev tsim kho ntsuab nyob rau hauv daim teb ntawm lub tsev Templates
Aluminium alloy formwork: Qhov feem ntawm6061-T6 alloyformwork siv nyob rau hauv cov tsev prefabricated nce mus txog 35%, thiab nws cov yam ntxwv ntawm reusable rau ntau tshaj 200 lub sij hawm txo cov kev tsim kho pov tseg los ntawm 90% piv rau cov ntoo formwork, uas ua tau raws li qhov yuav tsum tau ntawm "dual carbon" lub tswv yim.
5. Kev Tiv Thaiv Hauv Tebchaws thiab Kev Lag Luam Tub Rog: Kev Ua Haujlwm Zoo Tshaj Plaws hauv Ib puag ncig
Missile compartment: ZL205A alloy yog raug rau T77 kev kho cua sov kom muaj kev ruaj ntseg nyob rau hauv qhov kub ntawm -54 ℃ to 150 ℃, thiab yog siv rau cov txheej txheem ntawm lub cev missile lub cev.
Cov khoom siv nkoj: ZL305 alloy propellers muaj kev tiv thaiv corrosion tsawg dua 0.03mm / xyoo nyob rau hauv seawater immersion ib puag ncig, ncua lawv lub neej kev pab cuam peb zaug piv rau cov tsoos tooj liab alloys.
Ⅱ Kev ntsuas qhov ntev thiab cov cim tseem ceeb ntawm cam khwb cia txhuas alloys
Material Performance Evaluation System
Casting kev ua tau zoo: Nrog flowability (kav ntev ntev ≥ 500mm) thiab linear shrinkage tus nqi (≤ 1.2%) raws li cov ntsiab lus qhia, Al Si alloy tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tuag casting vim nws cov eutectic muaj pes tsawg leeg kom zoo dua.
Cov khoom siv kho tshuab: Lub zog tensile (σ b) thiab elongation (δ) yuav tsum tau ua kom haum rau daim ntawv thov scenario, xws li automotive kev ruaj ntseg Cheebtsam xav tau σ b ≥ 250MPa thiab δ ≥ 3%.
Kev kho cua sov teb: T6 lub xeev muaj 15% -20% nce lub zog piv rau T5 xeev, tab sis kev pheej hmoo ntawm kev ua hauj lwm hardening yuav tsum sib npaug.
Supply thiab xav tau tsom xam ntawm industrial chain
Cov khoom siv raw: Cov khoom seem ntawm cov khoom siv txhuas yog 59%, tab sis tseem muaj kev cuam tshuam kev lag luam (Malaysia thiab Thaib teb yog lub teb chaws tseem ceeb), thiab yuav tsum tau them nyiaj rau kev hloov pauv hauv 760200090 tariff txoj cai.
Kev tsim khoom kawg: Kev siv tus nqi ntawm cov khoom siv txhuas rov ua dua tshiab yog tsawg dua 55%, thiab kev lag luam concentration tus nqi CR10 tsuas yog 45%. Lub peev xwm tsim tawm tshiab tshiab hauv Anhui, Guangdong thiab lwm qhov chaw yuav raug tso tawm kom muaj zog (xav tias yuav ntxiv 2.66 lab tons hauv 2025).
Cov neeg siv khoom sab nrauv: Qhov kev loj hlob ntawm kev xav tau hauv kev lag luam tsheb muaj kev cuam tshuam nrog kev tsim cov tsheb tshiab lub zog (nrog rau kev sib raug zoo ntawm 0.82), thaum kev tsim kho kev lag luam cuam tshuam loj heev los ntawm txoj cai ntawm kev xa khoom.
Evolution Path of Process Technology
Melt purification technology: Txoj kev txhaj tshuaj rotary (RGI) ua tiav cov ntsiab lus hydrogen ntawm ≤ 0.15ml / 100gAl, uas yog 60% ntau dua li cov txheej txheem npuas.
Additive Manufacturing: Selective Laser Melting (SLM) thev naus laus zis ua rau ib lub sij hawm molding ntawm complex channel structural Cheebtsam, nce cov khoom siv mus txog 85%.
Simulation thev naus laus zis: ProCAST software simulates qhov kev xav ntawm qhov ntsws thiab xoob, coj qhov kev ua kom zoo ntawm cov nyiaj tsis zoo ntxiv, thiab txo cov seem seem los ntawm 2.3 feem pua cov ntsiab lus.
Kev lag luam tus nqi tsav tsheb
Tus nqi muaj pes tsawg leeg: Cov khoom seem txhuas nyiaj rau 90%, thiab qhov hloov pauv ntawm cov nqi hluav taws xob electrolytic yog kis los ntawm A00 txhuas tus nqi x luv nqi. Tus nqi ua tam sim no tseem nyob hauv thaj tsam ntawm 800-1200 yuan / tuj.
Nqe arbitrage: Qhov nruab nrab regression yam ntxwv ntawm tus nqi sib txawv ntawm ADC12 thiab A00 txhuas yog qhov tseem ceeb. Thaum tus nqi sib txawv tshaj 2500 yuan / tuj, qhov hloov pauv ntawm cov khoom pov tseg ua kom pom tseeb.
Cov khoom lag luam voj voog: Qhov piv ntawm cov khoom lag luam sib raug zoo rau cov khoom muag hauv tsev (15700 tons / 79000 tons) yog qhov keeb kwm qis, thiab peb yuav tsum tau ceeb toom rau cov mem tes xws li cuam tshuam ntawm kev ua lag luam ntxiv ntawm tus nqi.
Ⅲ Outlook ntawm Kev Txhim Kho Kev Lag Luam Kev Lag Luam
Txhim kho cov qauv kev thov: Qhov kev thov rau lub zog tshiab lub tsheb tuag-casting qhov chaw yuav nce 24% CAGR, tsav lub lag luam sib koom ntawm cov khoom siv hluav taws xob uas tsis muaj cua sov (xws li CNC-F) kom tshaj 30%.
Kev sib xyaw thev naus laus zis acceleration: Daim ntawv thov ntawm digital ntxaib thev naus laus zis hauv cov txheej txheem smelting tau ua tiav kev tswj hwm qhov tseeb ntawm ± 0.05% thiab cov txiaj ntsig ntawm 92%.
Txhim kho txoj cai cuam tshuam: Tom qab kev ua tiav tag nrho ntawm "rov qab them nqi" txoj cai, cov nqi se ntawm cov lag luam rov ua dua tshiab yuav tsum txo qis los ntawm 1.2 feem pua cov ntsiab lus, txhawb kev tso tawm ntawm cov peev txheej tsim tawm.
Qhov kev ntsuam xyuas no qhia tau hais tias kev lag luam casting aluminium alloy yog hloov los ntawm kev tsim khoom ib txwm mus rau peb-seem innovation ntawm "cov ntaub ntawv txheej txheem". Cov lag luam yuav tsum tsim kom muaj "kev ua tau zoo tus nqi xa khoom" hlau daim duab peb sab kev sib tw los tiv thaiv kev hloov pauv ntawm ob lub zog hloov pauv tshiab thiab kev tsim khoom ntse.
Yog li ntawd, qhov kev tso tawm ntawm tus nqi benchmark rau casting aluminium alloy yav tom ntej kev cog lus los ntawm Shanghai yav tom ntej traders rau lub rau hli ntuj 9th yog ib tug inevitable tshwm sim, uas tsis tsuas yog qhia txoj kev loj hlob ntawm lub domestic yav tom ntej kev lag luam pab rau kev lag luam tiag, tab sis kuj qhia Tuam Tshoj lub suab nrov nyob rau hauv lub ntiaj teb no txhuas pricing system. Nrog rau kev koom tes sib sib zog nqus ntawm cov neeg siv khoom lag luam, qhov ntau yam no xav kom dhau los ua qhov taw qhia tseem ceeb rau kev ntsuas cov khoom siv hluav taws xob tshiab.
