Muaj ob txoj kev sib koom ua ke feem ntau rau rebar: ib qho yog kom cais cov duab geometific, thiab hom kev sib cais raws li cov duab hla ntawm cov tav. Ntaus II. Qhov kev faib tawm no tsuas yog xav txog kev ua tau zoo ntawm cov rebar. Qhov thib ob yog raws li kev ua tau zoo (qib), xws li kuv lub teb chaws txoj kev siv nyiaj tam sim no yog 1499), raws li lub zog tam sim no (YEEN POINT) RebAR yog muab faib ua 3 qib; Nyob rau hauv Japanese muaj cov qauv (JI SG3112), Rebar tau muab faib ua 5 hom raws li kev ua tau zoo; Hauv tus qauv Askiv (BS4461), ntau qib ntawm Rebar cov kev xeem yuav tsum tau teev tseg. Tsis tas li ntawd, cov rebars tseem tuaj yeem raug cais raws lawv cov kev siv, xws li cov hlau hlau ua tib zoo siv thiab ua kom kub ceev cov pob zeb prestressed
Rebar yog ribbed steel bar rau saum npoo, kuj tseem hu ua ribbed steel bar, feem ntau nrog 2 txoj kev tav toj thiab tav su uas muaj raws li qhov ntev. Cov duab ntawm tus tav transverse yog kauv, herringbone thiab crescent puab. Qhia nyob rau hauv millimetres ntawm nominal lub taub. Lub nroog loj ntawm ib lub pob zeb ntawm lub pob zeb sib raug zoo rau cov kabinal uas hla ntawm ib puag ncig ntawm cov sib npaug. Lub cheeb tsam lub nroog rebar ntawm cov rebar yog 8-50 mm, thiab cov pom zoo ua diameters yog 8, 12, 20, 25, 25, thiab 40 hli. Ribbed steel cov tuav feem ntau yog raug rau cov kev ntxhov siab tensile hauv cov pob zeb. Vim tias qhov kev txiav txim ntawm pob tw, ribbed steel tuav tau muaj peev xwm sib raug zoo nrog cov pob zeb ua kom ruaj khov, yog li lawv tuaj yeem ua tau zoo dua nrog cov rog sab nraud. Ribbed steel tuav tau dav siv hauv ntau lub tsev qauv, tshwj xeeb tshaj yog loj, hnyav-walled thiab muaj kev txhim kho lub tsev.
Rebar yog tsim los ntawm cov mills me me, thiab cov milling me me Feem ntau ntawm cov tshiab thiab siv cov mills me me hauv ntiaj teb no tau ua tas mus li. Nrov rebar mills yog General-Kev Kub-Lub Hom Phiaj-Ceev Rolling Rebar Mills thiab 4-Hlais Cov Khoom Uas Rebar High-Lashar Mills.
Lub billet siv nyob rau hauv kev nruam me rolling zeb feem ntau txuas ntxiv billet, lub ntev yog feem ntau yog feem ntau ntawm 6 ~ 160 metres, thiab lub npov ib leeg yog 1.5 ~ 3 tons. Feem ntau ntawm cov xo yob yog hloov cov qauv qhia horizontally thiab ntsug, kom ua tiav torsion-dawb dov hla txoj kab. Raws li cov ntawv sib txawv thiab cov khoom lag luam tiav thiab cov khoom tiav, muaj 18, 20, 20, thiab 24 tus me dov mills, thiab 18 yog lub ntsiab. Bar dov rau feem ntau adopts cov txheej txheem tshiab xws li nqis cua sov cov cua sov, muaj kev kub siab dej descaling, tsawg-kub dov, thiab dov tsis kawg, thiab dov tsis kawg. Kev Rho Tawm Rolling thiab Intermediatic Rolling tau tsim kom hloov tau cov tsiaj loj thiab txhim kho dov qhov raug. Tiav cov mills feem ntau yog txhim kho qhov tseeb thiab nrawm (txog 18m / s). Cov khoom lag luam cov khoom lag luam feem ntau yog feem ntau yog feem pua EN10, thiab tseem muaj ф6-32mm lossis ф12-5mm. Tus qauv steel uas tsim yog cov hlau tsis muaj roj av, nruab nrab thiab muaj txiaj ntsig cov hlau uas tau xav tau ntau hauv kev ua lag luam; Qhov siab tshaj plaws yob ceev yog 18m / s. Nws cov txheej txheem ntau lawm yog raws li hauv qab no:
Taug kev rauv → Roughing Zeb → Code Interming Puring → Siv Lub Tshuab Khaub Ncaws Kub → Siv Lub Tshuab Khaub Ncaws Muab xam los ntawm cov rebar cov qauv: txheej Incepcexhos incham thiab hlau yog hlau chaw tsim khoom 6.00,295 Jiuzheng Hlau Thiab Hlau 141.2 Jiuzheng Hlau Thiab Hlau 161.58 Jiuzheng Hlau Thiab Hlau 182.00 Jiuzheng Hlau thiab Hlau 202.47 Jiuzheng Hlau Thiab Hlau 223.98 Jiuzheng Hlau Thiab Hlau 326.31 Jiuzheng Hlau Thiab Hlau.
