Tawm tsam keeb kwm yav dhau los ntawm kev nrawm nrawm thoob ntiaj teb kev tsim kho nroog thiab hauv - qhov tob zuj zus ntawm "dual carbon" cov hom phiaj, kev tsim kho kev lag luam tab tom hloov pauv ntau dhau los ntawm cov qauv kev tsim kho rau kev lag luam ntsuab. Nrog nws cov txiaj ntsig zoo xws li lub teeb yuag, lub zog siab, kev tsim kho tau zoo thiab kev ruaj ntseg ib puag ncig, cov qauv steel tau maj mam hloov cov qauv ua vaj tse, dhau los ua cov kev xaiv tseem ceeb rau cov chaw loj, super siab- cov tsev nce siab, cov nroj tsuag muaj kev lag luam thiab lwm yam, thiab txhaj tshuaj muaj zog rau hauv siab - kev loj hlob zoo ntawm kev tsim kho niaj hnub.
Cov kev sib tw tseem ceeb ntawm cov qauv steel stems los ntawm lawv cov khoom zoo heev thiab cov qauv zoo.Raws li cov khoom siv tseem ceeb, steel boasts cov khoom siv zoo heev: nws lub zog tensile tuaj yeem ncav cuag 200-500 MPa, deb tshaj ntawm cov pob zeb (10-40 MPa). Ntxiv mus, nws cov elastic modulus yog ib yam nkaus thiab ruaj khov, tso cai rau kev xam qhov tseeb ntawm cov qauv deformation thiab yog li muab cov khoom pov thawj rau kev ruaj ntseg hauv tsev.Raws li kev tsim kho kom zoo, cov khoom siv steel tuaj yeem ua tau raws li tus qauv hauv cov chaw tsim khoom, tsuas yog nyob rau ntawm - qhov chaw ua haujlwm yuav tsum tau ua. Qhov no txo qis lub sijhawm tsim kho uas siv los ntawm kev ua haujlwm ntub dej ib txwm siv, ua kom lub sijhawm luv luv los ntawm 30% -50% piv nrog cov qauv ua vaj tse. Piv txwv li, cov qauv tseem ceeb ntawm 10,000 m² steel qauv Rhiav tuaj yeem ua tiav hauv 45 hnub nkaus xwb los ntawm kev xa cov khoom mus rau qhov chaw, ua kom pom tseeb tias nws cov kev ua haujlwm siab thiab yooj yim.Ntau qhov tshwj xeeb, ib puag ncig-tus cwj pwm zoo ntawm cov qauv steel yog nyob rau hauv txoj kab nrog lub tswv yim ntawm kev loj hlob ntsuab. Tus nqi rov ua dua ntawm cov hlau ntau dua 90%- tom qab lub tsev raug rhuav tshem, cov khoom tuaj yeem yaj thiab rov ua dua tshiab, txo qis kev tsim kho pov tseg. Lub caij no, plua plav thiab suab nrov thaum lub sij hawm tsim kho muaj qis dua cov uas tsim los ntawm cov pob zeb ua pob zeb, ua cov qauv hlau zoo kawg nkaus ua raws li cov qauv vaj tsev ntsuab.
Los ntawm cov txiaj ntsig zoo no, daim ntawv thov scenarios ntawm steel qauv tau nthuav dav thiab nkag mus rau ntau lub sub-sectors ntawm kev tsim kho.Nyob rau hauv thaj chaw ntawm pej xeem vaj tse, loj - qhov chaw loj thiab cov chaw thauj mus los tau dhau los ua cov ntawv thov classic rau cov qauv hlau. Lub teb chaws Speed Skating Oval ("Ice Ribbon") rau Beijing Lub Caij Ntuj Sov Olympics tau txais cov qauv hlau hyperboloid, nrog rau tag nrho cov hlau siv tau txo los ntawm 40% piv nrog cov txheej txheem ib txwm muaj, ua tiav kev sib koom ua ke zoo tshaj plaws ntawm kev tsim vaj tsev zoo nkauj thiab qis -carbon ib puag ncig tiv thaiv. Lub chaw Guangzhou Nansha International Convention thiab Exhibition Center tau txais ib tug loj -span steel truss qauv nrog ib tug ncua sij hawm ntawm 60 meters, uas tsis tsuas yog xyuas kom meej lub meej mom ntawm lub exhibition chaw, tab sis kuj tiv thaiv qhov cuam tshuam ntawm typhoons nyob rau hauv ntug dej hiav txwv cheeb tsam.In the field of industrial buildings, steel structures are suited for the fast spans manufacturing and commissions. Ib tug loj tus naj npawb ntawm steel qauv systems tau txais yuav nyob rau hauv tej yaam num xws li lub Foshan Tsev Khoom Industrial Park thiab Dongguan Electronic Component Factory. Kev tiv thaiv- kev kho corrosion tau ua tiav rau qhov chaw ntub dej, sib npaug ntawm kev ua tau zoo thiab ua haujlwm ntev.Nyob hauv thaj chaw muaj xwm txheej ceev thiab cov tsev nyob, kev sib dhos ceev ceev thiab cov yam ntxwv ntawm cov hlau tsis sib haum ua rau lawv xaiv thawj qhov chaw hloov chaw nyob ib ntus tom qab muaj kev puas tsuaj. Tom qab muaj kev puas tsuaj dej nyab hauv qee thaj tsam ntawm Guangdong xyoo 2024, cov tsev hlau hloov chaw nyob ib ntus tau ua tiav hauv 7 hnub nkaus xwb. Meanwhile, prefabricated steel qauv vaj tse nyob tau maj mam nce thiab tau siv nyob rau hauv ib tug loj scale nyob rau hauv pheej yig vaj tse tej yaam num, daws qhov mob point ntawm lub sij hawm ntev ntawm kev tsim kho vaj tse nyob ib txwm.
Tam sim no, Tuam Tshoj txoj kev lag luam steel qauv tau tsim ua tiav kev lag luam saw system. Hauv xyoo 2023, kev tsim tawm ntawm cov qauv hlau tau mus txog 112 lab tons, sawv cev rau ib xyoos - ntawm - xyoo loj hlob ntawm 10.45%. Qib ntawm kev txawj ntse ntau lawm yog nce tsis tu ncua, nrog ntse txiav, vuam, thiab unmanned warehousing thiab logistics qauv dav saws thoob plaws lub sector.
Txawm li cas los xij, kev lag luam tseem ntsib ntau yam teeb meem: kev tsim kho tus nqi ntawm steel qauv vaj tse yog siab dua li ntawm cov qauv ib txwm muaj, tsim kom muaj kev tiv thaiv ntau heev rau kev nce qib; kev sib koom tes ntawm ntau lub koom haum hauv kev lag luam hauv kev lag luam yog qhov tsis txaus, thiab kev sib raug zoo ntawm cov txheej txheem tseem tsis sib xws; muaj qhov tsis txaus ntawm kev tsim qauv thiab kev tsim kho txuj ci, thiab kev paub txog kev sib raug zoo thiab kev lees paub yuav tsum tau txhim kho ntxiv.
Txhawm rau tsav txoj kev loj hlob ntawm kev lag luam, nws yog ib qho tsim nyog yuav tsum ntxiv dag zog rau kev taw qhia txoj cai thiab siv cov kev txhawb nqa xws li nyiaj txiag, se, thiab kev txhawb nqa nyiaj txiag; txhim kho cov txheej txheem txheej txheem thiab txhim kho kev sib raug zoo ntawm cov khoom siv steel qauv thiab cov cai hauv tsev; cob qhia cov txuj ci tshaj lij thiab txhawb nqa tag nrho cov peev txheej ntawm kev lag luam.
Saib tom ntej, nrog kev nce qib txuas ntxiv ntawm cov cai tsim kho prefabricated thiab hauv - qhov tob ntawm kev ua raws li "dual carbon" cov hom phiaj, kev lag luam feem ntawm cov vaj tsev steel yuav nce tsis tu ncua. Tam sim no, qhov kev faib ua feem ntawm steel qauv vaj tsev nyob rau hauv Tuam Tshoj tsuas yog 5% -7%, uas tseem tshuav ntau chav rau kev loj hlob piv nrog rau 30% -40% nyob rau hauv lub teb chaws tsim.Nyob rau hauv lub neej yav tom ntej, nrog rau R&D thiab siv cov ntaub ntawv tshiab xws li siab - lub zog steel thiab weathering steel, raws li zoo raws li nyob rau hauv - sib sib zog nqus kev koom ua ke ntawm ntse kev lag luam thiab cov qauv hlau yuav ua tiav cov qauv hlau. ntau teb. Lawv yuav tsis tsuas yog ua tus tsav tsheb tseem ceeb rau kev nthuav dav ntxiv ntawm kev lag luam steel, tab sis kuj tseem ua rau kev tsim kho kev lag luam mus rau lub sijhawm tshiab ntawm ntsuab, muaj txiaj ntsig thiab kev tsim kho kev lag luam, muab kev txhawb nqa zoo rau kev loj hlob ntawm kev lag luam hauv lub tebchaws.
