Taw Qhia: Kev nkag siab xim dub kav hlau
Hauv lub ntiaj teb kev lag luam kev lag luam, lo lusCov Yeeb Nkab Hlau DubFeem ntau tshwm sim nrogCov Yeeb Nkab HlauCov. Txawm hais tias cov kav dej dub dub yog cov txheej txheem ntawm cov pa roj carbon hlau, lawv muaj cov yam ntxwv tshwj xeeb uas teeb lawv sib nrug. Nkag siab cov nta no yog qhov tseem ceeb rau cov engineers, cov thawj coj, thiab cov thawj tswj haujlwm uas xav ua cov khoom haum.
Rau cov nyeem uas xav tau tag nrho kev sib piv ntawm ob cov khoom, peb pom zoo mus xyuas peb tsab xov xwm ntxaws ntxaws:Cov Yeeb Nkab Hlau Dub VS Carbon Hlau Yeeb Nkab.Cov ntawv tshawb fawb txog lawv qhov sib txawv ntawm qhov tob, thaum no ib qho tsom xam tshwj xeeb ntawm cov kav hlau dub, lawv cov khoom, qhov zoo, thiab cov ntawv thov.
Dab tsi yog cov yeeb nkab steel dub?
A Cov Yeeb Nkab Hlau DubYog cov yeeb nkab steel uas tsis tau malvanized lossis coated nrog lwm cov khaubncaws sab nraud pov hwm. Nws qhov tsaus ntuj nti los ntawm txheej txheej nyias ntawm hlau oxide tsim nyob rau saum npoo thaum lub sijhawm tsim khoom. Tsis zoo li Galvanized steel kav, uas yog coated nrog zinc rau kev tiv thaiv corrosion, cov kav hlau dub retain lawv cov nqaij nyoos.
Cov ntsiab lus tseem ceeb txog cov kav dej dub dub muaj xws li:
- Lawv tau ua feem ntau los ntawm cov hlau me me lossis nruab nrab.
- Lawv tsis muaj cov txheej ntxiv, uas muab rau lawv qhov txawv ntawm matte - black tsos.
- Lawv feem ntau yog tsim los ntawmERW (hluav taws xob tiv thaiv welded)lossisSeamless Yeeb Nkabtxoj kev tsim khoom.
Vim tias ntawm lawv cov kev tsim yooj yim thiab tus nqi yooj yim thiab tus nqi - Cov kav dej zoo yog qhov tsis zoo rau kev sib cav sib ceg.
Raug Thiab Khoom Muaj Peev Xwm
Dub hlau kav hlau dub yog tsim siv siab - Zoo Hlau Bille lossis Coils. Cov txheej txheem feem ntau ua raws li ib qho ntawm ob txoj kev:
- ERW Dub Hlau Yeeb Nkab: Steel Coils yog ib tug kws sau ua ke, zoo li ib daim ntawv cylindrical, thiab welded longitudinally siv hluav taws xob ntev siv hluav taws xob ntev.
- Seamless Dub Steel Yeeb Nkab: Cov tais diav tau chob thiab dov rau hauv lub nkoj hollow, tsim kav dej tsis muaj weld nqaws.
Khoom muaj pes tsawg leeg:
- Cov ntsiab lus carbon feem ntau yog li ntawm 0.05% thiab 0.25% thiab 0.25% (cov pa roj carbon) lossis nce li 0.30% (nruab nrab cov pa roj carbon hlau).
- Manganese, Sulfur, phosphorus, thiab silicon kuj tseem muaj nyob rau hauv me me.
Cov ntsiab lus carbon ua rau cov pa hluav taws xob muaj zog thiab ruaj ruaj, thaum tswj cov ntsej muag zoo thiab weldability. Txawm li cas los xij, tsis muaj kev kho mob ntxiv, cov kav dub dub yog qhov tsis yooj yim rau xeb ntawm cov av noo lossis xeb.
Cov yam ntxwv tseem ceeb ntawm dub steel kav
Dub hlau kav hlau tau xaiv tau dav rau lawv tus nqi - ua tau zoo thiab versatility, tab sis lawv kuj muaj kev txwv.
