Kev lag luam thoob ntiaj teb ntawm cov ntawv hlau galvanized yuav ua rau pom peb qhov kev hloov pauv tseem ceeb: kev hloov pauv ntawm kev thov mus rau cov khoom lag luam siab, kev siv cov thev naus laus zis ntsuab thiab cov pa roj carbon tsawg, thiab kev hloov pauv hauv cheeb tsam ntawm cov khoom xa tuaj.

Cov Kev Lag Luam Ib Txwm: Kev Tsim Kho thiab Tsheb Tseem Yog Kev Txhawb Nqa Tseem Ceeb

Kev Tsim Kho

Saudi Arabia lub "Vision 2030" tau tsav 4.13 trillion riyals ntawm kev nqis peev hauv kev tsim kho vaj tse, nrog rau kev lag luam tsim kho hauv Saudi mus txog $ 74.1 billion txog xyoo 2025. Nws kwv yees tias yuav loj hlob ntawm tus nqi txhua xyoo ntawm 5.4% rau tsib xyoos tom ntej, ua rau muaj kev thov ntxiv rau cov ntawv hlau coated ua cov ntaub ntawv kho kom zoo nkauj phab ntsa sab nraud.

Kev Lag Luam Tsheb

Kev tsim cov tsheb fais fab tshiab thoob ntiaj teb yuav tshaj 20 lab units txog xyoo 2025, ua rau muaj kev thov ntau ntxiv rau cov ntawv hlau galvanized muaj zog heev. Piv txwv li, cov ntawv hlau galvanized muaj zog heev uas muaj zog ntawm 600MPa thiab siab dua twb tau siv ntau heev rau cov roj teeb, thiab cov hlau duplex qib 1180MPa tau ua tiav qhov hnyav txo 20% hauv cov tsheb.

Cov Kev Lag Luam Tshiab: Photovoltaics thiab Cov Tsev Ntsuab Ua Rau Kev Loj Hlob Tshiab

Cov kev teeb tsa photovoltaic tshiab ua rau muaj kev xav tau cov qauv txhawb nqa zinc-aluminium-magnesium (ZM). Cov ntawv hlau coated nrog qhov ntsuas kev sim ntsev ntawm 2000 teev tau dhau los ua qhov kev xaiv zoo tshaj plaws, nrog rau qhov kev thov nce ntxiv 200% txhua xyoo hauv xyoo 2023. Lub tsev ntsuab yog qhov tsav tsheb ntawm kev siv cov ntawv hlau galvanized uas tiv taus xeb hauv cov tsev nyob uas muaj cov qauv hlau, nrog rau qhov feem pua ​​ntawm cov tsev nyob uas muaj cov qauv hlau hauv thaj av Yangtze River Delta xav tias yuav nce mus txog 25% txog xyoo 2025.

Cov Txheej Txheem Ntsuab Hloov Cov Txuj Ci Ib Txwm

Tus nqi nkag mus ntawm cov thev naus laus zis passivation uas tsis muaj chromium yuav ncav cuag 65% los ntawm xyoo 2025, hloov hexavalent chromium kom ua tau raws li EU RoHS cov lus qhia; zinc-aluminium-magnesium coatings txo cov zinc txheej tuab los ntawm 30% thiab ob npaug ntawm lub neej.

Ib lub kaw lus rov ua dua cov kua qaub pov tseg uas kaw tau ua tiav 100% rov siv dua cov kua qaub pickling, txo cov nqi ib puag ncig rau ib tuj hlau los ntawm 80 yuan. Cov tuam txhab ua lag luam xws li Baosteel lub hauv paus Zhanjiang tau pom tias muaj kev txo qis 30% ntawm cov pa phem VOCs piv rau xyoo 2020.

Kev Tsim Khoom Txawj Ntse Txhim Kho Kev Ua Haujlwm Zoo

Cov tshuab pom kev AI saib xyuas qhov sib npaug ntawm cov txheej txheem hauv lub sijhawm tiag tiag, ua tiav qhov tseeb ntawm kev txheeb xyuas qhov tsis zoo ntawm 99.2%; cov chaw tsim khoom digital twin kwv yees qhov zinc slagging 48 teev ua ntej, txo qhov poob ntawm lub sijhawm tsis ua haujlwm. Tom qab siv ntawm Baowu lub hauv paus, kev siv hluav taws xob ib tuj hlau txo qis 12%, thiab kev siv zinc txo qis 4.7%.

Tuam Tshoj txoj kev zoo dua ntawm kev xa khoom mus rau lwm lub teb chaws txuas ntxiv mus, tab sis ntsib kev nyuaj siab ntawm kev hloov pauv

Xyoo 2025, Tuam Tshoj cov hlau coated xa tawm ntau tshaj 21 lab tons, nrog rau cov teb chaws Es Xias Qab Teb thiab Middle East ua cov lag luam tseem ceeb. Saudi Arabia cov khoom xa tuaj txog 677,000 tons (nce 44.82%) txhua xyoo.

Tus nqi xa khoom nruab nrab raug kev nyuaj siab, poob rau $ 629.49 / ton thaum Lub Kaum Ib Hlis 2025 (txo 80% txij thaum pib ntawm xyoo 2023), yuam cov tuam txhab hloov ntawm "kev sib tw nqi" mus rau "kev sib tw nqi."

Kev Tsim Kho Lub Peev Xwm Hauv Cheeb Tsam Tiv Thaiv Cov Teeb Meem Kev Lag Luam

Cov nqi roj carbon CBAM ntawm EU yuav ua rau cov nqi xa khoom nce ntxiv 8% -12%, ua rau cov tuam txhab Suav ua kom sai dua kev tsim kho Hoobkas hauv Southeast Asia thiab Middle East (xws li Baosteel txoj kab tsim khoom hauv Malaysia), tsim cov qauv "Tuam Tshoj R&D + kev tsim khoom txawv teb chaws".

Lub peev xwm galvanizing tshiab hauv cov lag luam tshiab xws li Is Nrias teb thiab Qaib Cov Txwv yuav cuam tshuam rau Tuam Tshoj txoj kev xa khoom tawm. Cov tuam txhab yuav tsum tau sib sau ua ke lawv cov khoom lag luam siab los ntawm kev txhim kho thev naus laus zis (xws li cov ntawv hlau galvanized muaj zog heev).
