Lub sijhawm tshiab muab sijhawm rau kev txhim kho ntawm txhuas thiab txhuas alloys
Raws li lub sijhawm txhim kho, tib neeg muaj kev xav tau ntau dua rau kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev nyab xeeb. Kev loj hlob ntawm kev lag luam aluminium ua lub luag haujlwm hloov tsis tau hauv kev txhim kho peb yam.
1. Aluminium yog cov khoom siv txuas ntxiv. Cov khoom siv txhuas hauv lub ntiaj teb crust yog nplua nuj heev, thiab cov khoom siv txhuas tuaj yeem rov ua dua thiab siv dua. Nws txuag lub zog thiab txo cov pa phem. Aluminium zoo li tau dhau los ua cov khoom siv uas tsis muaj peev xwm siv tau los ntawm tib neeg lub sijhawm ntev tsawg kawg.
2. Aluminium coil yog cov khoom siv tseem ceeb rau kev sib sib zog nqus thiab kev qhia hauv aerospace thiab kev thauj mus los niaj hnub.
3. Daim ntawv thov dav ntawm aluminium coil hauv kev tsim kho tuaj yeem txo qhov hnyav tag nrho ntawm lub tsev, tso cai rau ntau yam khoom siv los tsim lub teeb yuag, txo cov khoom pov tseg, thiab rau qee qhov, nws kuj yog kev txuag.
4. Lub neej kev pab cuam ntawm aluminium coil thiab aluminium alloys ntev dua li cov khoom siv hlau zoo tib yam. Vim qee yam ntawm nws tus kheej cov yam ntxwv, txhuas tuaj yeem tsim cov oxide txheej thaum siv, yog li txo cov xeb.
Nws tuaj yeem pom tau tias aluminium coil thiab cov ntaub ntawv txhuas tuaj yeem ua lub luag haujlwm hauv kev txhim kho ib puag ncig, txuag cov peev txheej, thiab txuag hluav taws xob.
Aluminium coil thiab aluminium cov ntaub ntawv yuav ua lub luag haujlwm tseem ceeb hauv cov ntaub ntawv yooj yim.
Txoj kev loj hlob sai thiab dav siv ntawm txhuas thiab txhuas alloy cov ntaub ntawv muaj, rau ib qho twg, hloov steel raws li cov khoom siv yooj yim rau tag nrho cov kev lag luam thiab tib neeg tag nrho.
Nrog rau kev nce qib txuas ntxiv ntawm txoj cai dual-carbon, rov qab muaj peev xwm tsim tau raug tshem tawm thiab cov chaw tsim khoom uas twb muaj lawm tau raug txhim kho kom ua tiav kev txuag hluav taws xob thiab txo qis emission.
Kev tiv thaiv corrosion siab, zoo heev zog-rau-qhov hnyav piv thiab zoo formability ua txhuas ib tug loj industrial hlau nyob rau hauv kev tsim kho, tsheb thauj mus los, ntim thiab machinery thiab khoom. Qhov nce hauv qhov nkag mus ntawm lub zog tshiab hauv kev ua lag luam tsheb thiab kev txhim kho ntawm lub cev lub cev hnyav tau tsav qhov kev loj hlob sai ntawm kev thov aluminium. Raws li keeb kwm yav dhau los ntawm kev loj hlob ruaj khov, kev tsim hluav taws xob tshiab tseem xav kom tsim kho. Kev tsim kho ntawm photovoltaics thiab cov phiajcim hluav taws xob tau txhawb nqa ntau qhov kev faib ua feem ntawm txhuas siv hauv cov khoom siv hluav taws xob thiab hluav taws xob.
Judging los ntawm cov kev loj hlob tam sim no tiam sis nyob rau hauv lub teeb yuag teb, aluminium coil alloys tej zaum yuav ua ib tug tshiab tiam ntawm cov khoom tsim nyob rau hauv lub neej yav tom ntej. Hlau muaj tus nqi qis tshaj, tab sis qhov hnyav txo qhov hnyav yog qhov tsis zoo; aluminium nqi ntau thiab qhov hnyav txo qhov ntau yog ob qho tib si hauv ntau yam zoo; titanium thiab magnesium tus nqi kuj yog siab, qhov ceev ntawm magnesium yog li ntawm 1/2 ntawm txhuas, tab sis tus nqi yog 3 npaug ntawm aluminium Times, tam sim no kev lag luam qis dua li ntawm txhuas; Cov ntaub ntawv carbon fiber ntau muaj qhov zoo tshaj plaws txo qhov hnyav, tab sis tam sim no tus nqi siab dhau lawm.
Vim muaj qhov tshwj xeeb zoo ntawm aluminium, nws tau tsim sai heev. Tam sim no, lub ntiaj teb electrolytic aluminium ntau lawm tau tshaj 68 lab tons thiab tseem loj hlob sai heev. Nws tuaj yeem pom tias kev lag luam txhuas tau dhau los ua qhov tseem ceeb hauv kev tsim khoom hauv lub tebchaws.
Destocking yuav txhim kho qhov zoo, thiab cov nqi txhuas yuav nkag mus rau lub voj voog tsim txiaj
Tam sim no, kev sib raug zoo ntawm cov khoom lag luam ntawm electrolytic aluminium hauv Suav teb tau poob qis thiab tab tom qhia txog kev destocking. Raws li SMM cov ntaub ntawv, kev sib raug zoo ntawm cov khoom lag luam ntawm electrolytic aluminium nyob rau ntau thaj tsam ntawm lub teb chaws tau nce ntxiv txij li thaum kawg ntawm lub Kaum Ob Hlis 2022, thiab nyob rau lub Peb Hlis 2, 2023, nws tau mus txog qhov siab tshiab ntawm 1.269 lab tons txij li lub Plaub Hlis 27, 2020, thiab tom qab ntawd tig downward, nrog kev poob qis. Qhib. Raws li qhov kawg ntawm lub Plaub Hlis, piv nrog cov ntsiab lus siab tshaj plaws, cov khoom muag poob los ntawm 416, 000 tons, poob ntawm 38.24%. Electrolytic aluminium yog tam sim no qhia txog kev destocking. Txij li thaum nkag mus rau lub quarter thib ob, cov khoom lag luam electrolytic aluminium tau nkag mus rau theem txo qis raws caij nyoog, thiab tag nrho cov khoom lag luam kev ua tau zoo yog txhim kho. LME + electrolytic aluminium cov khoom lag luam hauv kev sib pauv yav dhau los yog nyob rau hauv keeb kwm qis, thiab cov khoom muag qis txwv cov chav rau kev kho txuas ntxiv hauv cov nqi txhuas. Raws li ntawm 2023Q1, LME cov khoom muag yog 520,900 tons, thiab Shanghai Futures Exchange inventories yog 206,900 tons, tag nrho 727,800 tons, cov khoom muag qis tshaj plaws hauv kaum xyoo dhau los. Txij li thaum tag nrho cov khoom lag luam ntawm electrolytic aluminium poob qis dua 1 lab tons liab kab thaum Lub Ob Hlis 25, 2022, nws tau txuas ntxiv poob. Kev txiav ntau lawm ntawm ntau tus smelters tau txuas ntxiv nthuav dav kev lag luam sib txawv. Txawm hais tias txawv teb chaws tseem yuav nyob rau hauv lub voj voog ntawm cov paj laum, kev nce ntxiv ntawm cov paj laum yuav cuam tshuam rau kev siv txawv teb chaws. Raws li cov neeg Esxias kev lag luam rov qab los, Fed cov paj laum nce qeeb, thiab kev thov nce, cov khoom muag qis yuav txhawb nqa cov nqi txhuas ntxiv, thiab cov nqi txhuas yuav tsum nkag mus rau lub voj voog nce.
