Thaum muaj kev hloov kho dua tshiab ntawm cov khoom siv txhuas thoob ntiaj teb, Guinea tau tuav txoj sia ntawm kev lag luam txhuas thoob ntiaj teb.
Muaj 7.4 billion tons ntawm cov bauxite uas siv tau, cov hlau uas tsis muaj silicon ntau thiab cov hlau uas muaj alumina ntau nrog cov alumina txog li 45% -62%, nrog rau cov txiaj ntsig ntuj tsim ntawm kev faus tob thiab kev khawb av yooj yim, Guinea tswj hwm ntau dua 70% ntawm kev lag luam bauxite thoob ntiaj teb hauv hiav txwv. Qhov tseem ceeb, 74% ntawm Tuam Tshoj cov bauxite xa tuaj los ntawm Guinea, ua rau nws yog lub hauv paus tseem ceeb ntawm kev muab cov khoom siv raw rau Tuam Tshoj kev lag luam txhuas.
Nrog rau kev siv tag nrho ntawm Guinea's Simandou 2040 National Plan, tag nrho cov peev txheej dhau 15 xyoo ncav cuag 200 billion US dollars, nrog rau theem thawj zaug (2025-2030) ncav cuag 65 billion US dollars, hloov kho tag nrho cov kev xav ntawm kev txhim kho kev lag luam hauv zos.
Tsoomfwv Guinea tau txhawb nqa cov cai tswjfwm tshiab rau kev txhawb nqa cov peev txheej. Los ntawm kev rov qab tau cov cai tsis siv neeg hauv kev khawb av, tswj cov khoom tsim tawm kom ruaj khov, thiab ua kom muaj kev ua haujlwm hauv zos, nws txwv tsis pub xa tawm cov hlau nyoos yooj yim, yuam kom bauxite raug ua hauv zos rau hauv alumina, electrolytic aluminium thiab aluminium ingots.
Cov tuam txhab ua lag luam Suav teb suav nrog Aluminum Corporation of China (CHINALCO), SMB Winning Consortium thiab SPIC tau ua tus thawj coj hauv kev tsim qauv, pib tsim 1.2 lab tons ntawm cov khoom siv alumina txhua xyoo ib qho tom qab ib qho, thiab pib tag nrho cov saw hlau kev lag luam ntawm "bauxite - alumina - electrolytic aluminium - aluminium ingot". Guinea tab tom hloov pauv sai sai los ntawm ib lub tuam txhab xa khoom mus rau hauv lub hauv paus tsim khoom txhuas hauv Africa.
Los ntawm qhov kev xav ntawm kev hloov pauv kev lag luam, thaum bauxite raug smelted rau hauv alumina, kev muab tag nrho cov peev xwm rau hauv electrolytic aluminium ntau lawm yuav tsim ib qho kev lag luam loj heev.
Raws li kev xam suav theoretical hauv kev lag luam, 1.2 lab tons ntawm alumina tuaj yeem tsim tau txog 635,300 tons ntawm electrolytic aluminium. Tom qab rho tawm kev poob electrolysis hauv kev lag luam thiab kev poob kub casting, qhov tseeb ruaj khov ntawm cov txhuas ingots ncav cuag 610,000 txog 615,000 tons.
Ib txoj kab tsim khoom txhuas uas muaj peev xwm tsim tau txhua xyoo ntawm 600,000 tons yuav tsum siv li 300,000 tons ntawm cov anodes ua ntej ci thiab 15,000 tons ntawm cov pa roj carbon cathode txhua xyoo. Raws li cov khoom siv tseem ceeb thiab cov khoom tseem ceeb ntawm kev tsim cov txhuas electrolytic, lub peev xwm muab khoom thiab kev tswj hwm zoo ntawm cov anodes ua ntej ci ncaj qha txiav txim siab qhov kev ua haujlwm ruaj khov, txo nqi thiab kev txhim kho kev ua haujlwm ntawm cov haujlwm txhuas electrolytic hauv zos hauv Guinea.
Hauv cov txheej txheem tsim cov anodes ua ntej, lub tshuab kneading thiab forming preheating yog ib qho khoom siv tseem ceeb, npog tag nrho cov txheej txheem ntawm cov khoom qhuav proportioning, qhov kub tas li kneading, paste hloov kho thiab vibration forming.
Nws feem ntau ua haujlwm los sib tov cov pa roj carbon aggregates xws li roj av coke thiab pitch coke nrog pitch binder, ua tiav shearing, kneading thiab infiltration fusion nyob rau hauv kev tswj qhov kub kom meej kom tsim cov yas homogeneous, uas tom qab ntawd yog tsim kom meej rau hauv cov anode blocks txheem.
Qhov tseeb ntawm kev sib tsoo thiab tsim cov txheej txheem cuam tshuam ncaj qha rau qhov ntom ntom, kev ua hluav taws xob thiab lub zog kho tshuab ntawm anodes, thiab ntxiv rau kev siv hluav taws xob, kev ua haujlwm tam sim no thiab tus nqi tsim khoom ntawm cov khoom siv electrolytic aluminium, ua lub hauv paus tseem ceeb rau kev ua haujlwm zoo thiab kev siv tsawg ntawm cov kab ntau lawm electrolytic aluminium.
Tam sim no, Guinea ntsib teeb meem loj heev hauv kev txhawb nqa cov chaw rau nws txoj kev lag luam txhuas hauv zos. Txawm hais tias alumina thiab electrolytic aluminium muaj peev xwm ua haujlwm sai, cov peev xwm txhawb nqa xws li prebaked anodes thiab cathode carbon blocks tsis txaus, thiab cov saw hlau txhawb nqa kev lag luam suav nrog cov ntaub ntawv refractory, caustic soda thiab cov khoom siv carbon yuav luag tsis muaj dab tsi.
Nrog rau kev kos npe thiab kev tshaj tawm ntawm CHINALCO qhov project alumina 1.2 lab-ton, thiab kev tsim kho sai ntawm cov project alumina ntawm SMB thiab SPIC, ntau cov kab ntau lawm electrolytic aluminium yuav raug tshaj tawm ntau, ua rau muaj kev thov ntau rau cov txheej txheem kneading & forming uas ua haujlwm tau zoo thiab loj.
Lub hom phiaj ntawm kev thov kev loj hlob ntawm Guinea kev lag luam txhuas hauv zos, lub tshuab ua kom sov ua ntej thiab tsim cov txheej txheem muaj ntau qhov zoo xws li kev hloov pauv mus rau qhov muaj peev xwm loj, kev txuag hluav taws xob thiab kev txo qis kev siv, kev ruaj khov zoo thiab kev sib raug zoo nrog kev ua haujlwm thiab kev saib xyuas hauv zos.
HWAPENGKev Ua Ntej Ua Kub thiab Kneading System ZoothiabLub tshuab tsim HP-EVC800 Extrusion VibrocompactorSiv cov thev naus laus zis tswj qhov kub thiab txias kom raug nrog qhov yuam kev ntsuas qhov kub thiab txias tswj tau hauv ± 2 ℃, cov khoom siv tuaj yeem ua tiav kev ua haujlwm ntawm cov khoom qhuav ua ntej cua sov, kev sib tsoo siab thiab kev ua kom txias;
Nws tuaj yeem ua kom cov khoom tiav anode nce ntxiv 2% -5%, txo kev siv suab ntau dua 2%, nce qhov ntom ntom ntawm cov khoom tsim los ntawm 0.02 units, thiab txo qis kev poob ntawm cov khoom siv electrolysis thiab cov nqi khiav lag luam.
Lub caij no, tus qauv tsim modular hloov kho rau kev teeb tsa thiab kev ua haujlwm ntawm cov haujlwm txawv teb chaws, thiab cov qauv kaw kaw tiv thaiv kev xau ntawm cov hmoov av thiab cov pa phem, ua raws li Guinea cov cai tiv thaiv ib puag ncig thiab ua tau raws li qhov kev thov txhawb nqa rau anode carbon blocks ntawm cov kab ntau lawm txhuas ingot nrog cov zis txhua xyoo ntawm 600,000 tons thiab siab dua.
Saib mus tom ntej, tsav los ntawm Guinea cov cai thiab tag nrho cov saw hlau kev lag luam ntawm Suav cov tuam txhab, kev ua tiav tob hauv zos ntawm bauxite tau dhau los ua qhov sib txawv tsis hloov pauv, thiab lub peev xwm ntawm electrolytic txhuas thiab txhuas ingots yuav txuas ntxiv nthuav dav.
Raws li cov khoom siv tseem ceeb rau kev tsim cov anode ua ntej, lub tshuab ua kom sov thiab tsim cov txheej txheem yuav ua kom tiav qhov sib txawv ntawm kev lag luam txhuas hauv Guinea, dhau los ua qhov chaw nkag tseem ceeb los teeb tsa txoj kev lag luam txhuas hauv Africa thiab sib qhia cov nyiaj faib ntawm kev ua haujlwm hauv zos, thiab pab cov tuam txhab Suav txhim kho lub voj voog kaw ntawm tag nrho cov saw hlau kev lag luam ntawm "cov peev txheej + cov khoom siv hauv paus + kev ua haujlwm + cov chaw txhawb nqa", ntxiv tshawb nrhiav kev lag luam dej hiav txwv xiav ntawm kev lag luam txhuas hauv Guinea.
