Classification ntawm deformed steel tuav

Muaj ob hom kev faib tawm rau rebar: ib qho yog raws li cov duab geometric, uas tau muab faib los yog muab faib raws li qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib nrug ntawm qhov sib txawv.Piv txwv li, hauv British Standard (BS4449), rebar muab faib ua hom I thiab hom II.Qhov kev faib tawm no feem ntau qhia txog kev ua haujlwm ntawm cov hlau deformed.Thib ob, raws li kev faib tawm (qib), piv txwv li, nyob rau hauv cov qauv kev tswj hwm tam sim no ntawm peb lub teb chaws, lub rebar yog (G B1499.2-2007) thiab cov hlua hlau yog 1499.1-2008), lub rebar muab faib ua peb. qib raws li qib zog (yield point / tensile zog);Raws li tus qauv kev lag luam Nyij Pooj (JI SG3112), rebar muab faib ua tsib pawg raws li nws cov khoom siv dav;Lub British Standard (BS4461) kuj qhia txog ntau qib ntawm kev ua tau zoo rau cov hlau tuav deformed.Tsis tas li ntawd, rebar kuj tuaj yeem raug cais raws li nws lub hom phiaj, xws li cov rebar zoo tib yam rau cov pob zeb ua kom muaj zog thiab cov cua sov kho rebar rau prestressed reinforced pob zeb.

Cov deformed steel tuav tau muab faib ua cov khoom kub-kuav los tiag steel tuav thiab nplua-grained kub-kuav los tiag steel tuav.Raws li lub ntsiab lus ntawm tus qauv, zoo tib yam kub dov steel tuav yog steel tuav xa nyob rau hauv kub-kuav los tiag mob.Nws cov qauv metallographic feem ntau yog tsim los ntawm ferrite thiab pearlite, thiab yuav tsum tsis muaj lwm yam qauv uas cuam tshuam rau kev ua haujlwm.Qhov zoo-grained kub dov steel bar hais txog cov nplua-grained steel bar tsim los ntawm kev tswj dov thiab tswj cov txheej txheem txias thaum lub sij hawm kub dov txheej txheem.Nws cov qauv metallographic feem ntau yog tsim los ntawm ferrite thiab pearlite, thiab yuav tsum tsis muaj lwm yam qauv cuam tshuam rau kev ua haujlwm, thiab cov nplej loj yuav tsum tsis txhob coarser dua qib 9.

Qib zoo tib yam kub dov ribbed steel bar yog tsim los ntawm HRB, tus yam ntxwv tus nqi ntawm yield zog thiab anti-seismic kos npe (+ E);Qib ntawm nplua-grained kub dov ribbed steel bar yog tsim los ntawm HRBF, tus yam ntxwv tus nqi ntawm yield zog thiab anti-seismic kos npe (+ E);F yog thawj tsab ntawv Fine.Ordinary kub dov steel bar qib tau muab faib ua tsib qib: HRB400, HRB500, HRB600, HRB400E thiab HRB500E;Cov qib ntawm cov nplua-grained kub dov steel tuav tau muab faib ua HRBF400, HRBF500, HRBF400E thiab HRBF500E.

Ntsia hlau xov hlau yog siv dav hauv kev tsim kho vaj tse xws li tsev, txuas hniav thiab txoj kev.Los ntawm txoj kev loj, railways, txuas hniav, culverts, tunnels, tswj dej nyab, dams thiab lwm yam pej xeem chaw, mus rau lub hauv paus, kab teeb, kab, phab ntsa, daim hlau, thiab rebar ntawm lub tsev thiab cov vaj tse yog indispensable yam ntxwv cov ntaub ntawv.Tam sim no, HRB400 lossis HRB400E steel tuav tau siv dav hauv ntiaj teb.Peb lub tuam txhab tuaj yeem hloov kho HRB500, HRB600 thiab lwm lub zog siab deformed steel tuav.
