Hauv kev tsim kho, muaj ntau hom hlau uas siv ntau, ntawm cov uas yog cov tuav puag ncig thiabhlauyog qhov tshwm sim ntau tshaj plaws. Qhov sib txawv tseem ceeb ntawm lawv yog raws li nram no. Hnub no, peb yuav tham luv luv txog cov kev sib txawv no.
Cov Tuav Puag Ncig (HPB Series)
Cov hlau puag ncig nto du heev. Yog tias muab tso rau hauv cov pob zeb ua vaj tse, lawv tuaj yeem rub tawm nrog kev rub me ntsis xwb.
Cov hlau txuas (HRB Series)
Sab nraud ntawm cov hlau rebar muaj cov tav zoo li kauv. Ib txhia zoo li lub hli crescent, thaum lwm tus zoo li kauv.
Lub hom phiaj ntawm cov tav no yog kom tuav cov pob zeb kom nruj, kom ntseeg tau tias lawv yeej tsis tso tseg txawm tias raug kev ntxhov siab thiab kev hloov pauv.
Kab puag ncig (HPB300)
Cov hlau puag ncig yog cov hlau carbon, nrog rau qib hlau hu ua Q235. Nws muaj lub zog nruab nrab, nrog rau lub zog tso zis ntawm kwv yees li 300 MPa. Cov txiaj ntsig: kev tawv siab thiab yooj yim khoov.
Cov hlau (HRB400E)
Cov hlau rebar yog cov hlau uas tsis muaj hlau ntau. Cov hlau rebar HRB335 yog 20MnSi (20 manganese-silicon). Cov hlau rebar HRB400 yog 20MnSiV, 20MnSiNb, 20MnTi, thiab lwm yam. Nco ntsoov tias tus "E" - nws sawv cev rau kev tiv taus av qeeg.
Nws tsis tsuas yog tiv taus kev sib txhuam xwb tab sis kuj muab lub zog tensile zoo tshaj plaws.
Muaj ntau tus neeg siv khoom nug tias, "Puas yog cov hlau rebar hnyav dua li cov hlau puag ncig uas muaj tib lub cheeb?"
Raws li kev xav: Lawv hnyav ib yam!
Hauv cov qauv theoretical calculation ntawm lub teb chaws tus qauv, los pab txhawb kev lag luam thiab kev suav nyiaj, tsis hais tus naj npawb ntawm cov tav ntawm qhov chaw, qhov hnyav theoretical ib 'meter' rau ribbed rebar thiab round bar ntawm tib lub cheeb yog xam siv cov qauv unified.
Tau kawg, qhov tseeb, cov hlau ribbed rebar hnyav dua me ntsis vim yog cov ribs ntxiv (qhov no hu ua "kev hloov pauv tsis zoo"), tab sis thaum xam cov nqi khoom siv, txhua tus siv tib "kev ntsuas."
