Siab-Lub Zog Hlau Tsav Kev Loj Hlob: Tuam Tshoj txoj kev lag luam steel qauv nkag mus rau lub sijhawm muaj zog thiab kev txawj ntse
Nov 27, 2025
Txij li xyoo 2025, Tuam Tshoj txoj kev lag luam steel qauv tau pom dual resonance ntawm "kev ua lag luam tawg thiab kev lag luam tawg": kev lag luam nplai ntawm siab - lub zog thiab siab -torsion integrated steel Cheebtsam tau nce ob zaug hauv ob xyoos, cov khoom siv thev naus laus zis tau tawg mus rau txawv teb chaws monopoly, thiab daim ntawv thov scenarios} tau nthuav dav los ntawm {3} teb. Qhov no yog qhov kev nkag mus rau Tuam Tshoj txoj kev lag luam steel qauv rau hauv ib qho kev txhim kho tshiab uas yog "siab zog, siab txawj ntse, thiab daim ntawv thov dav".
"Blowout" Kev Lag Luam nthuav dav, Super Projects li Core Cav
Kev loj hlob tawg ntawm cov qauv steel ntu tau dhau los ua qhov tshwj xeeb tshaj plaws ntawm kev lag luam. Cov ntaub ntawv qhia tau hais tias kev lag luam hauv tsev loj ntawm siab - lub zog thiab siab - torsion integrated steel Cheebtsam tau nce los ntawm 654 lab yuan hauv 2023 txog 1.362 billion yuan hauv 2024, nrog rau ib xyoos - ntawm - xyoo kev loj hlob ntawm 108.26%. Tom qab qhov kev loj hlob no, kev tsim kho hnyav ntawm super siab- cov tsev nce siab thiab cov choj loj tau tsim muaj kev xav tau kev txhawb nqa. Tam sim no, Tuam Tshoj muaj 40% ntawm lub ntiaj teb skyscrapers tshaj 300 meters, nrog 27 tshiab super siab -nce vaj tse nyob rau hauv 2024, muab siab heev xav tau ntawm kev ua tau zoo ntawm steel Cheebtsam. Lub 600-meter landmark lub tsev nyob rau hauv Shenzhen tau txais siab- lub zog steel Cheebtsam nrog ib tug yield zog ntawm 690MPa, txo tag nrho cov qauv hnyav los ntawm 15% thiab nce cua load kuj los ntawm 30%. Lub Hutong-Sutong Yangtze River Railway Choj siv Q500QE siab- lub zog steel, nrog ib qhov ntev ntawm 1,092 meters, teeb tsa lub ntiaj teb cov ntaub ntawv. Kev xav tau hauv kev lag luam pej xeem tseem muaj zog: hauv 2024, kev yuav khoom ntawm siab - lub zog steel Cheebtsam rau hauv nroog qhov chaw siv hluav taws xob thiab cov tsev prefabricated tau nce 65%. Ib txoj haujlwm siv hluav taws xob hauv peb lub nroog -tier nroog tau txais cov khoom siv hlau hnyav, ua kom lub sijhawm siv sijhawm luv luv los ntawm 40% thiab txo cov nqi kho lub neej tag nrho los ntawm 25%. Cov kws tshuaj ntsuam xyuas kev lag luam kwv yees tias ntu qhov ntsuas yuav ntau dua 200 lab yuan hauv xyoo 2025, nrog rau kev loj hlob txhua xyoo yuav tsum nyob twj ywm siab dua 25% hauv kaum xyoo tom ntej.
Technology Leap los ntawm "Ua raws" mus rau "Tus Thawj Coj", Dual Breakthroughs hauv Khoom thiab Txheej Txheem
Tuam Tshoj cov txheej txheem steel qauv tau ua tiav qhov tseem ceeb ntawm kev dhia ntawm "tus ua raws" mus rau "tus thawj coj", ua tiav tag nrho cov kev lag luam tawm txawv teb chaws. Hauv cov ntaub ntawv, los ntawm kev tsim kho tshiab hauv microalloying thiab tswj cov txheej txheem dov / txias, cov chaw lag luam hauv tsev tau nce lub zog ntawm cov hlau los ntawm 460MPa mus rau 785MPa, nrog qis- qhov kub thiab txias (tshwj xeeb lub zog ntawm -40 degree) tshaj 200J, mus txog qib siab thoob ntiaj teb. Lub "siab-toughness reinforced steel qauv" tsim los ntawm Hunan Zhongwei Kejian Co., Ltd. refines lub grain loj kom tsawg dua 1 micron, ncua lub neej qaug zog los ntawm 3 zaug, thiab tau siv nyob rau hauv lub restoration ntawm ntau lub teb chaws tej yaam num tseem ceeb. Cov txheej txheem tsim khoom kuj tau tsim kho tshiab: lub tuam txhab tau qhia "laser-arc hybrid vuam thev naus laus zis", ua kom cov vuam ua tau zoo los ntawm 50% thiab tswj qhov tsis xws luag hauv qab 0.05%. Nws tsim "variable-section box tivthaiv" los ntawm topology optimization tsim txo qhov hnyav los ntawm 20% thaum nce bearing muaj peev xwm los ntawm 18%, dhau los ua cov kev daws teeb meem rau cov chaw ntau pob ntev.
Kev nthuav dav Daim Ntawv Thov Ciam Tebchaws, Hla -Kev Sib Txuas Ciam Teb Qhib Qhov Chaw Tshiab
Kev lag luam steel qauv tau tawg los ntawm cov kev txwv ntawm cov tsoos infrastructure, txuas mus rau siab -kawg khoom tsim thiab lwm yam teb, tsim ib tug multi-scenario daim ntawv thov qauv. Nyob rau hauv lub zog tshiab, offshore cua turbine yees siv siab - lub zog steel Cheebtsam tau txo qhov hnyav ntawm ib qho - tshuab txhawb nqa los ntawm 12% thiab cov nqi los ntawm 8%. Hauv kev tsim hluav taws xob xwm txheej kub ntxhov, cov khoom siv hlau modular tau txo lub sijhawm tsim kho ntawm cov tsev kho mob hauv thaj chaw los ntawm 72 teev mus rau 8 teev, ua lub luag haujlwm tseem ceeb hauv kev cawm thaum muaj xwm txheej ceev. Los ntawm kilometer{11}}theem tob- hiav txwv drilling platforms rau reusable foob pob ua ntxaij lub cev, los ntawm underground utility tunnels mus rau super high-nce vaj tse, siab{14}}lub zog steel Cheebtsam tau dhau los ua cov khoom tseem ceeb txhawb kev txhim kho ntawm ntau yam high{15}}kawg teb.
Los ntawm kev loj hlob ntawm kev lag luam mus rau kev ywj pheej tswj hwm ntawm cov thev naus laus zis thev naus laus zis, thiab ntau yam txuas ntxiv ntawm cov ntawv thov scenarios, Tuam Tshoj txoj kev lag luam steel yog tsav los ntawm "kev txhim kho lub zog + kev txawj ntse empowerment", tsis tsuas yog dhau los ua "hardcore footnote" ntawm infrastructure lub zog tab sis kuj yog ib qho qauv ntawm cov khoom siv technology txhawb kev lag luam tiag.
