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 kem, steel trusses thiab lwm yam khoom ua los ntawm cov seem steel thiab steel daim hlau, thiab siv silanization, ntshiab manganese phosphating, ntxuav thiab ziab, galvanizing thiab lwm yam xeb tshem tawm thiab antirust txheej txheem. feem ntau yog txuas nrog welds, bolts los yog rivets.Vim nws lub teeb yuag thiab kev tsim kho yooj yim, nws yog dav siv nyob rau hauv loj factories, venues, super high-rise thiab lwm yam teb.Steel qauv yog ib qho yooj yim rau xeb, dav hlau qauv rau xeb, galvanized los yog pleev xim rau, thiab ua haujlwm tsis tu ncua.
Hlau yog tus cwj pwm los ntawm lub zog siab, lub teeb yuag, zoo zuag qhia tag nrho, muaj zog tiv thaiv deformation, yog li nws yog tshwj xeeb tshaj yog haum rau kev tsim kho ntawm qhov loj thiab super siab, super hnyav vaj tse; Cov khoom muaj homogeneity zoo thiab isotropy thiab yog ib qho zoo tagnrho elastomer. , uas feem ntau ua raws li cov kev xav ntawm kev siv tshuab engineering. Cov khoom muaj cov yas zoo thiab tawv, tuaj yeem muaj qhov loj deformation, thiab muaj peev xwm dais lub dynamic load zoo. Lub sij hawm siv luv luv; Nrog rau qib siab ntawm industrialization, tshwj xeeb ntau lawm nrog siab. degree ntawm mechanization tuaj yeem ua tiav.
Lub zog siab steel yuav tsum tau kawm los txhim kho cov txiaj ntsig taw tes lub zog ntawm cov qauv steel.Ntxiv rau, cov hlau tshiab yuav tsum tau dov, xws li H-beam (tseem hu ua dav flange steel) thiab T-shaped steel thiab profiled steel phaj rau ua tau raws li qhov xav tau ntawm cov qauv loj loj thiab cov tsev siab siab.
Tsis tas li ntawd, tsis muaj tshav kub choj lub teeb steel qauv system, lub tsev nws tus kheej tsis yog lub zog txuag, cov thev naus laus zis no nrog kev sib txuas tshwj xeeb los daws cov teeb meem ntawm lub tsev kub thiab txias; Cov qauv me me tso cai rau cov kav dej thiab cov kav dej sab saud thiab qis. kom dhau los ntawm phab ntsa, uas yooj yim rau kev tsim kho thiab kho kom zoo nkauj.
Cov yam ntxwv ntawm steel qauv
1, cov khoom siv zog yog siab, nws qhov hnyav yog lub teeb
Hlau muaj lub zog siab thiab cov qauv ntoo thiab cov qauv ntoo yog qhov tsawg, lub teeb yuag, yooj yim thauj thiab kev teeb tsa, haum rau loj span, siab siab, bearing qauv.
2, steel toughness, zoo plasticity, khoom uniformity, siab structural ntseeg
Haum rau kev coj tus kheej cuam tshuam thiab dynamic load, nrog zoo seismic kev ua tau zoo.Lub sab hauv ntawm steel yog ib yam, nyob ze rau lub isotropic homogenous lub cev.Qhov tseeb ua hauj lwm ntawm steel qauv conforms rau lub xam qhov kev xav.Yog li cov steel qauv muaj kev ntseeg siab.
3. Kev tsim thiab kev teeb tsa ntawm cov qauv steel yog cov tshuab ua haujlwm siab heev
Steel qauv cov tswv cuab yog ib qho yooj yim los tsim nyob rau hauv lub Hoobkas thiab sib sau ua ke ntawm site.Lub Hoobkas mechanized manufacturing ntawm steel qauv Cheebtsam muaj qhov zoo ntawm high precision, high efficiency efficiency, ceev qhov chaw sib dhos ceev thiab lub sij hawm siv luv luv.Steel qauv yog ib qho ntawm feem ntau industrialized. cov qauv.
4, steel qauv sealing kev ua tau zoo
Vim tias cov qauv welded tuaj yeem raug kaw tag nrho, nws tuaj yeem ua rau hauv cov hlab ntsha siab nrog cov huab cua zoo thiab cov dej nruj, cov pas dej loj loj, cov kav dej siab thiab lwm yam.
5. Steel qauv yog kub-resistant thiab tsis hluav taws-resistant
Thaum qhov kub thiab txias qis dua 150℃, cov khoom ntawm steel hloov me ntsis.Yog li ntawd, steel qauv yog tsim rau kub rhiav, tab sis qhov saum npoo ntawm cov qauv los ntawm txog 150 degrees ntawm thermal tawg, yuav tsum tau tiv thaiv los ntawm tshav kub rwb thaiv tsev board.Qhov kub ntawm 300.℃thiab 400℃Lub zog steel thiab elastic modulus txo qis, thiab lub zog steel nyhav rau xoom thaum qhov kub thiab txias yog li 600℃.Hauv cov tsev uas muaj kev tiv thaiv hluav taws tshwj xeeb, cov qauv hlau yuav tsum tau tiv thaiv nrog cov ntaub ntawv refractory los txhim kho qhov ntsuas hluav taws kub.
6, steel qauv corrosion kuj tsis zoo
Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntawm ntub thiab corrosive xov xwm, yooj yim rau xeb.General steel qauv rau xeb, galvanized los yog xim, thiab kev tu ncua.Tshwj xeeb ntsuas xws li "zinc thaiv anode tiv thaiv" yuav tsum tau saws los tiv thaiv corrosion ntawm offshore platform qauv hauv dej hiav txwv.
7, cov pa roj carbon tsawg, txuag hluav taws xob, kev tiv thaiv ib puag ncig ntsuab, tuaj yeem rov qab siv dua
Lub demolition ntawm steel qauv tsim yuav luag tsis muaj kev tsim kho pov tseg thiab cov hlau tuaj yeem rov ua dua.
