HRB400 lub ntsiab lus?

Dab tsi yog steel rebars HRB400 txhais li cas? Yuav Xaiv Cov Rebar li cas?

HRB400Suav lub npe yog kub dov ribbed bar, inch yog 6 ~ 100mm. Lub teb chaws yuav tsum tau ua qauv GB1499. {2 -- 2007 "fears cam khwb cia ribbed bar" txij lub Peb Hlis 1, 2008 pib siv. Tus qauv tso tawm lub zog ntawm cov hlau bar HRB400 yog 400MPA, thiab tus qauv tsim yog 360MPA.

1, HRB yog lub hardness tus nqi, txhais tau tias kub-dov ribbed-dog dig ribbed bar, yog hais tias muaj pes tsawg hrb, tus lej tom qab yog lub zog ntawm lub bar.

2, Thib Peb Qib Rebars (HRB400 saum toj no) tseem yog xov hlau Rebars, muaj zog dua, tab sis tus nqi kuj siab, tau nce maj mam txhawb nqa.

3. Cov txheej txheem theem nrab steel bar (hrb335) yog threaded steel bar, lub cheeb tsam ntawm {2}} yog feem ntau, siv nyob rau hauv cov kab, txhua, shear phab ntsa thiab lwm yam. Tsis muaj teeb meem ntau npaum li cas txoj kab uas hla yog, nws tsis tshua siv nyob rau hauv Civil thiab kev tsim kho. Nws feem ntau siv nyob rau hauv pawg pob zeb ua, xws li hydraulic engineering.

4, thawj qib steel bar (HPB300) yog feem ntau du hlau, nquag hu ua hlau qws,}} rounds ntawm feem ntau. Hauv architecture, nws yog feem ntau siv los ua stirrups, faib bars ntawm daim hlau, ntaus, thaiv phab ntsa, phab ntsa lub zog thiab lwm yam.

Kub-Ribbed steel bar feem ntau yog hu ua threaded steel bar, feem ntau nrog ob lub laub ntev thiab hloov pauv ntawm qhov ntev. Cov duab ntawm cov tav cug tig yog kauv, herringbone, thiab crescent. Cov txheej txheem Suav Suav cov qauv txheej txheem hais tias nws yog crescent. Lub nroog loj ntawm tus hlau bar yog 6 ~ 50mm. Ribbed steel cov tuav feem ntau dais tensile kev ntxhov siab hauv cov pob zeb ua, thiab vim muaj cov nyhuv ntawm cov tav, lawv muaj kev sib raug zoo dua nrog cov pob zeb.

 

 

 

►High lub zog:HRB400 STEEL STEED muaj cov nuj nqis muaj txiaj ntsig lub zog thiab qhov kawg lub zog thiab tuaj yeem tiv thaiv loj loj.

Osgood Dutrility:Txawm tias thaum cov txiaj ntsig tau tshaj, cov hlau tuav hlau yuav tsis tawg tam sim thiab muaj qee yam muaj peev xwm ua tau zoo.

►Hot dov txheej txheem:Tsim los ntawm cov txheej txheem kov kub, cov hlau tuav hauv cov hlau, uas nce cov hlau tuav thiab pob zeb ua kom zoo nkauj ntawm cov kev ua tau zoo ntawm kev siv ua vaj tse tag nrho.

Lub ntsiab sib txawv yog tias HRB400E muaj cov yeeb yaj kiab seismic. Tag nrho cov hlau tuav nrog cov yeeb yaj kiab cov yeeb yam tau raug xa mus ua E-tuav.

Ntawm no, HRB400E hais txog ib theem ntawm 400MPA nrog cov seismic kev ua haujlwm. Ib qho ntxiv, tus yuam sij rau hom steel bar no yog tias super-resul anio tsis yog loj heev thiab lub elongation tsis tuaj yeem me me.

Cov kab hlau tshiab tau ntsib cov txheej txheem ntawm kev txhim kho los ntawm lub zog tsawg kom muaj zog dua.

1.High-nce tsev: Vim yog Thyi siab thiab ua kom loj dua, hre400 steel cov tuav yog qhov haum rau cov kab ke tseem ceeb xws li cov kab key thiab begms hauv hich-sawv.

2. Choj Engineering: Hauv kev tsim kho ntawm cov choj, HRB400 steel kab tuaj yeem muab tensie tsim nyog kom ntseeg tau tias lub sib tsoo thiab sofabety ntawm lubbridge qauv.

3.Txoj kev tsim qauv: HRB400 cov hlau txuas kuj tau siv hauv kev tsim kho ntawm kev tsim kho xws li txoj kev thiab cov kev ua kom raws li cov qauv ntawm cov qauv ntawm cov txheej txheem thiab kev ruaj khov.

HRB400Bar steel yog ib tug steel bar nrog tsis zoo weldability. Raws li cov ntaub ntawv hauv cov lus sib xyaw saum toj no, cov pa hluav taws xob ntawm HRB4 {1}}}}}} {}} pa roj ntsha tuaj yeem tswj tau ntawm 0.4% tam sim no.

Raws li peb ntau xyoo ntawm cov kev paub ntau lawm, thaum cov roj carbon thiab alloy steel tsis yog ntau tshaj li}}}}}. 4%, tus weldability}. 4%, tus weldability ntawm cov hlau yog qhov zoo; Thaum cov pa hluav taws xob sib npaug yog nruab nrab ntawm 0. 4% thiab tswj tau}. Thaum cov pa hluav taws xob muaj ntau dua 0.6%, qhov nyuaj rau Weld steel, thiab nws yog qhov nyuaj preheating, thiab kev ntsuas kub ntau ntxiv.

Piv nrog Q235 steel, hrb400 steel ntxiv ib qho txheej txheem quenching kom ua rau cov hlau dees tsis kam ntawm cov hlau zoo dua; Nyob rau tib lub sijhawm, ntxiv cov txheej txheem tempering ua cov khoom siv ntawm cov hlau muaj zog dua, txo qhov muaj peev xwm ua tau ntawm cov koom haum sib txawv ntawm cov hlau yooj yim rau corrode. Yog li ntawd, txoj kev corrosion ntawm HRB400 steel zoo dua li ntawm Q235 hlau.

Hauv cov ntsiab lus, HRB400 steel bar, raws li lub siab-zog thiab siab-ductility kub-ribbed steel bar, ua lub luag haujlwm tseem ceeb hauv kev tsim kho cov haujlwm. Nws cov txheej txheem ntau lawm thiab ntau cov kev siv ua nws ib qho ntawm kev tsis taus thiab cov ntaub ntawv tseem ceeb hauv kev lag luam kev tsim kho.
