1, Txheej txheem cej luam ntawm steel qauv kev lag luam

Cov qauv hlau yog cov qauv tsim los ntawm cov khoom siv hlau, uas yog ib qho ntawm cov qauv tseem ceeb ntawm lub tsev. Cov qauv no tsuas yog tsim los ntawm cov kab hlau, steel kab, steel trusses thiab lwm yam khoom ua los ntawm cov hlau thiab steel phaj, thiab siv silane, ntshiab manganese phosphating, dej ntxuav, ziab, galvanizing thiab lwm yam kev tshem tawm xeb thiab xeb tiv thaiv txheej txheem. Vuam seams, bolts lossis rivets feem ntau yog siv los txuas cov tswv cuab lossis cov khoom. Vim nws lub teeb yuag thiab kev tsim kho yooj yim, nws tau siv dav hauv cov nroj tsuag loj, qhov chaw, super siab thiab lwm qhov chaw. Nws muaj cov yam ntxwv hauv qab no: 1. Cov khoom siv muaj zog thiab lub teeb yuag; 2. steel toughness, zoo plasticity, cov khoom siv tsis zoo, kev ntseeg siab ntawm cov qauv; 3. High degree ntawm mechanization nyob rau hauv steel qauv tsim thiab installation; 4. Zoo sealing kev ua tau zoo ntawm steel qauv; 5. Steel qauv yog kub-resistant tab sis tsis hluav taws-resistant; 6. Tsis zoo corrosion kuj ntawm steel qauv; 7. Cov pa roj carbon tsawg, txuag hluav taws xob, ntsuab thiab rov siv dua.

2 、 Kev tsim kho ntawm steel qauv kev lag luam

Nyob rau hauv xyoo tas los no, Tuam Tshoj txoj kev lag luam steel qauv tau ntsib cov txheej txheem los ntawm kev pib qeeb mus rau kev loj hlob sai. Xyoo 2016, lub xeev tau tshaj tawm ntau cov ntaub ntawv txoj cai los daws cov teeb meem ntawm steel overcapacity thiab txhawb kev loj hlob ntsuab thiab ruaj khov ntawm kev tsim kho kev lag luam. Xyoo 2019, Ministry of vaj tse thiab kev tsim kho hauv nroog hauv nroog tau tshaj tawm "cov ntsiab lus tseem ceeb rau 2019 kev ua haujlwm ntawm kev tsim kho kev lag luam saib xyuas lub tuam tsev ntawm Ministry of vaj tse thiab kev txhim kho hauv nroog nyob deb nroog", uas yuav tsum tau ua tiav kev sim ua haujlwm ntawm steel qauv prefabricated vaj tsev; Thaum Lub Xya Hli 2019, Lub Tsev Haujlwm Saib Xyuas Vaj Tse thiab Kev Txhim Kho Hauv Nroog Hauv Nroog tau ua tiav tau pom zoo cov qauv kev sim ntawm Shandong, Zhejiang, Henan, Jiangxi, Hunan, Sichuan, Qinghai thiab lwm xya lub xeev los txhawb kev tsim cov qauv hlau loj prefabricated vaj tsev.

Raws li kev cuam tshuam ntawm cov kev cai zoo, kev lag luam xav tau thiab lwm yam, qhov kev tsim kho tshiab ntawm steel qauv prefabricated lub tsev tau nce ze li ntawm 30%. Lub teb chaws steel qauv tso zis kuj qhia tau hais tias ib tug ruaj khov upward trending xyoo los ntawm lub xyoo, nce los ntawm 51 lab tons nyob rau hauv 2015 mus rau 71.2 lab tons nyob rau hauv 2018. Nyob rau hauv 2020, lub steel qauv tso zis ntau tshaj 89 lab tons, accounting rau 8.36% ntawm cov crude steel. ,
