Nyob rau theem loj ntawm kev lag luam hlau thoob ntiaj teb, cov qauv hlau zoo li cov kav hlau uas ntsuas qhov zoo thiab cov lus qhia ntawm cov khoom. Cov qauv hlau hauv ntau lub tebchaws thiab thaj chaw sib txawv, zoo li cov suab paj nruag sib txawv, txhua tus ua si ib zaj nkauj tshwj xeeb. Rau cov tuam txhab koom nrog kev lag luam hlau thoob ntiaj teb, kev ua kom raug qhov sib piv ntawm cov qauv no yog qhov tseem ceeb rau kev qhib lub qhov rooj rau kev lag luam zoo. Nws tsis tsuas yog tuaj yeem ua kom ntseeg tau tias cov hlau uas ua tau raws li qhov xav tau raug yuav, tab sis kuj zam ntau yam kev tsis sib haum xeeb los ntawm kev nkag siab yuam kev ntawm cov qauv hauv kev muag khoom, thiab txo cov kev pheej hmoo ntawm kev lag luam. Niaj hnub no, peb yuav tsom mus rau cov qauv hlau Lavxias thiab cov qauv hlau Suav, tshuaj xyuas tob txog kev sib piv ntawm cov khoom siv ntawm lawv, thiab tshawb nrhiav qhov tsis paub meej.
Kev txhais lus ntawm cov khoom siv hlau txheem Suav teb
Tuam Tshoj txoj kev tsim cov qauv hlau zoo li lub tsev zoo nkauj, nruj thiab muaj txheej txheem. Hauv qhov system no, cov hlau carbon feem ntau yog sawv cev los ntawm cov qib xws li Q195, Q215, Q235, thiab Q275. "Q" sawv cev rau lub zog tawm los, thiab tus lej yog tus nqi ntawm lub zog tawm los hauv megapascals. Piv txwv li, siv Q235, nws muaj cov pa roj carbon nruab nrab, kev ua tau zoo, lub zog sib koom ua ke, kev ua tau zoo thiab kev vuam, thiab siv dav hauv kev tsim kho thiab kev tsim kho, xws li kev tsim cov thav duab cog, cov pej thuam xa hluav taws xob siab, thiab lwm yam.
Cov hlau uas tsis muaj hlau ntau kuj tseem ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, xws li Q345, Q390 thiab lwm yam qib. Q345 hlau muaj cov khoom siv kho tshuab zoo heev, cov khoom siv vuam, cov khoom ua haujlwm kub thiab txias thiab kev tiv thaiv corrosion. C, D thiab E qib Q345 hlau muaj qhov kub thiab txias zoo thiab feem ntau siv rau hauv cov khoom siv vuam siab xws li nkoj, boilers thiab cov hlab siab. Nws qib zoo yog los ntawm A txog E. Thaum cov ntsiab lus tsis huv txo qis, qhov cuam tshuam tawv nce ntxiv, thiab nws tuaj yeem hloov kho rau cov chaw siv nruj dua.
Kev tshuaj xyuas ntawm cov khoom siv hlau txheem Lavxias
Lub teb chaws Russia tus qauv hlau yog tsom mus rau tus qauv GOST, zoo li ib qho kev sib tw tshwj xeeb nrog nws tus kheej txoj kev tsim kho. Hauv nws cov hlau carbon, cov qib hlau xws li CT3 yog ntau dua. Hom hlau no muaj cov ntsiab lus carbon nruab nrab thiab siv dav hauv kev tsim khoom siv tshuab, kev tsim kho thiab lwm yam teb, xws li kev tsim khoom ntawm qee qhov me me, thiab kev tsim kho ntawm cov ntoo thiab cov kem hauv cov qauv tsev ib txwm muaj.
Hais txog cov hlau uas tsis muaj zog thiab muaj zog heev, cov qib xws li 09G2С ua tau zoo heev. Nws muaj qhov sib piv tsim nyog ntawm cov khoom sib xyaw, muaj zog siab thiab kev ua haujlwm vuam zoo, thiab feem ntau siv los tsim cov khoom loj xws li choj thiab nkoj. Hauv kev tsim choj, nws tuaj yeem tiv taus cov khoom loj thiab kev sim ntawm ib puag ncig ntuj kom ntseeg tau tias lub choj ruaj khov. Hauv cov haujlwm tso roj thiab roj av hauv Lavxias, cov hlau uas ua tau raws li cov qauv Lavxias feem ntau tuaj yeem pom. Nrog kev tiv thaiv corrosion zoo heev thiab lub zog siab, lawv hloov kho rau cov xwm txheej geological thiab huab cua hnyav thiab xyuas kom meej tias muaj kev nyab xeeb ntawm kev thauj mus los hluav taws xob. Piv nrog cov qauv Suav, cov hlau txheem Lavxias muaj qhov sib txawv ntawm cov kev cai thiab kev ua tau zoo ntawm qee cov ntsiab lus, thiab qhov sib txawv no kuj ua rau lawv tus kheej cov yam ntxwv hauv cov xwm txheej thov sib txawv.
Cov ntsiab lus sib piv ntawm cov khoom siv hlau ntawm Tuam Tshoj thiab Lavxias
Yuav kom nthuav qhia tau yooj yim dua txog kev sib piv qib khoom siv ntawm cov hlau txheem Lavxias thiab cov hlau txheem Suav, cov hauv qab no yog daim ntawv qhia sib piv ntawm cov hlau feem ntau:
Piv txwv li, siv cov hlau kav dej. Hauv qhov project Sino-Lavxias teb chaws koom tes ua haujlwm, yog tias sab Lavxias siv cov hlau K48, sab Suav siv tau L360 hlau hloov. Ob qho no muaj kev ua tau zoo sib xws hauv lub zog thiab kev tawv, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov kav dej kom tiv taus kev nyuaj siab sab hauv thiab ib puag ncig sab nraud. Hauv kev tsim kho, thaum cov haujlwm tsim kho hauv Lavxias siv cov hlau C345, Tuam Tshoj cov hlau Q345 kuj tseem tuaj yeem ua haujlwm zoo nrog cov khoom siv kho tshuab zoo sib xws thiab kev vuam zoo kom ntseeg tau tias muaj kev ruaj khov ntawm cov qauv tsev. Qhov kev sib piv qib khoom siv no yog qhov tseem ceeb hauv kev lag luam tiag tiag thiab kev tsim kho. Nws tuaj yeem pab cov tuam txhab sib phim cov kev xav tau thaum yuav thiab siv cov hlau, xaiv cov hlau kom zoo, txo cov nqi, txhawb kev txhim kho ntawm kev lag luam hlau Sino-Lavxias teb chaws, thiab muab kev txhawb nqa zoo rau kev ua tiav ntawm ntau yam haujlwm tsim kho.
Xaiv Jindalai los qhib tshooj tshiab hauv kev koom tes hlau
Hauv lub ntiaj teb loj ntawm kev lag luam hlau Sino-Lavxias teb sab, Jindalai Steel Company zoo li lub hnub qub ci ntsa iab, ci ntsa iab. Peb ib txwm ua raws li kev nrhiav kev zoo. Txij li kev yuav khoom siv raw mus rau kev tsim khoom thiab kev ua tiav, peb tswj hwm txhua txoj kev kom ntseeg tau tias txhua pawg hlau ua tau raws li lossis tshaj qhov qauv tsim nyog, muab kev lees paub zoo rau cov neeg siv khoom.
Nrog cov khoom siv tsim khoom siab heev thiab kev tswj hwm zoo, peb muaj peev xwm muab khoom tau zoo. Txawm tias nws yog ib pawg me me ntawm cov xaj ceev lossis kev koom tes ntev ntev, peb tuaj yeem teb sai, xa khoom raws sijhawm thiab ntau kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom. Peb paub zoo tias kev pabcuam zoo yog lub hauv paus ntawm kev koom tes. Pab pawg muag khoom tshaj lij yeej ib txwm npaj los muab cov kev pabcuam sab laj rau cov neeg siv khoom. Txij li kev xaiv khoom mus rau kev faib khoom, txhua qhov txuas tau teeb tsa zoo kom cov neeg siv khoom tsis txhob txhawj.
Yog tias koj muaj kev xav tau hauv kev yuav khoom hlau, txawm tias koj xav tau cov hlau txheem Lavxias lossis cov hlau txheem Suav, thov koj xav tiv tauj peb. Peb tos ntsoov yuav ua haujlwm nrog koj los qhib tshooj tshiab ntawm kev koom tes hlau thiab tsim kom muaj kev ci ntsa iab ntxiv rau ntawm theem ntawm kev lag luam hlau Sino-Lavxias.
