HRB400 HRB500 ASTM A615 Gread 60 75 Hlau Rebar
Qhov sib txawv ntawm rebar thiab tiaj puag ncig steel tuav yog tias rebar muaj longitudinal thiab transverse tav ntawm nws nto, feem ntau nrog ob longitudinal tav thiab transverse tav tusyees faib raws nws ntev. Rebar yog ib hom me me -section steel, feem ntau yog siv los ua cov pob txha ntawm cov pob zeb ua vaj tse. Nws yuav tsum muaj qee yam kev siv zog, khoov deformation, thiab weldability. Cov khoom siv raw rau kev tsim cov rebar yog carbon structural steel los yog tsawg-alloy structural steel uas tau undergone tua melting kev kho mob. Cov khoom tiav tau muab xa tuaj rau hauv kub- dov, normalized, los yog kub-rolled mob.
Kub-rolled ribbed steel tuav tau muab faib ua peb qib: HRB335 (yav tas los 20MnSi), HRB400 (yav tas los 20MnSiV, 20MnSiNb, 20Mnti), thiab HRB500. American ASTM A615 tus qauv siv Qib 60, Qib 75, thiab lwm yam, nrog rau cov lej sib raug rau cov khoom muaj zog hauv ksi. Cov txheej txheem European EN 10080 siv tsab ntawv B ua raws li tus lej, xws li B500B sawv cev rau tus yam ntxwv yield zog ntawm 500 MPa thiab nruab nrab ductility. Lub Japanese Industrial Standard JIS G3112 siv SD390, SD490, thiab lwm yam., qhov twg SD qhia cov hlau reinforcement thiab tus lej sawv cev rau qhov tsawg kawg nkaus yield zog.
Hauv kev siv engineering, cov qib sib txawv ntawm cov hlau txhawb nqa ua haujlwm sib txawv. HRB335 feem ntau yog siv rau cov khoom nruab nrab lossis qis- cov tsev nce siab, HRB400 tau dhau los ua cov hlau tseem ceeb hauv cam khwb cia-hauv- qhov chaw ua vaj tse, thiab HRB500 yog tsim rau hnyav- load scenarios xws li cov tub ntxhais tubes ntawm super high -nce vaj tse thiab ntev - ncua choj. Rau tshwj xeeb ib puag ncig engineering, corrosion kuj yog ib qho tseem ceeb xav txog; epoxy-coated steel reinforcement yog cim nrog "Ep" tom qab nws lub npe, thiab stainless hlau reinforcement siv lub prefix "SUS".

Peb Qhov Zoo
Ob yam khoom siv tes ua
Qib ntawm nplua- nplej kub- dov steel bar yog ua raws li cov lus Askiv luv luv ntawm "kub-rolled ribbed steel bar" nrog thawj tsab ntawv ntawm "zoo" ua lus Askiv (Fine). Xws li: HRBF335, HRBF400, HRBF500. Cov qib siv tau rau cov qauv seismic nrog cov kev xav tau siab dua: Ntxiv E tom qab cov qib uas twb muaj lawm (piv txwv li: HRB400E, HRBF400E).
Daim ntawv thov tseem ceeb: Siv dav hauv kev tsim vaj tsev, txuas hniav, txoj kev thiab lwm yam engineering engineering.
Cov khoom lag luam txaus
Rebar series nrog nominal diameters ntawm 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm. Qhov ntev ntawm cov khoom siv tau muab faib ua ob hom: ntev ntev thiab ob qhov ntev. Kev xaiv ntau yam ntawm export rebar tsau ntev yog 6 ~ 12m. Cov lus qhia saum toj no thiab qhov ntau thiab tsawg muaj cov khoom lag luam loj txhua xyoo puag ncig.Win 10,000 tons, nws tuaj yeem ntim thiab xa tuaj tsis pub dhau peb hnub.
Saib xyuas kom meej
Qhov saum npoo zoo xav kom qhov kawg yuav tsum tau txiav ncaj, thiab qhov saum npoo yuav tsum tsis txhob muaj cov kab nrib pleb, caws pliav thiab quav, thiab yuav tsum tsis txhob muaj kev puas tsuaj rau kev siv, thiab lwm yam.
Txoj kev khoov ntawm rebar thiab qhov yuav tsum tau muaj ntawm cov duab geometric ntawm lub steel bar Lub bending℃ntawm qhov ncaj steel bar yuav tsum tsis txhob cuam tshuam rau kev siv ib txwm, thiab tag nrho cov dabtsi yog khoov℃yuav tsum tsis txhob ntau tshaj 0.4% ntawm tag nrho cov ntev ntawm steel bar.
Siv tau scene
Kev lag luam xav tau rau rebar yog ze rau kev tsim kho kev lag luam. Nrog rau kev nrawm ntawm cov txheej txheem hauv nroog, qhov kev thov rau kev tsim kho cov phiaj xwm tseem loj hlob, thiab qhov kev thov rau rebar tseem nce ntxiv. Kev ua lag luam muaj qhov xav tau ntau tshaj plaws rau rebar nrog lub cheeb ntawm 8mm / 10mm / 12mm. Nrog rau kev nce qib ntawm loj - nplai kev tsim kho vaj tse, qhov kev thov rau 14mm / 16mm txoj kab uas hla rebar yog maj mam nce.
