Yuav ua li cas kom paub qhov txawv ntawm cov hlau pas nrig thiab rebar?

Yog dab tsitus pas hlau

Hauv cov lus yooj yim, cov hlau coiled yog hlau, uas yog, dov rau hauv lub voj voog los ua lub hoop, qhov kev tsim kho uas yuav tsum tau ncaj, feem ntau yog txoj kab uas hla ntawm 10 lossis tsawg dua.
Raws li qhov loj ntawm lub cheeb, uas yog, qib ntawm tuab, thiab muab faib ua pawg hauv qab no:

 

Hlau puag ncig, bar, hlau, kauj
Hlau puag ncig: qhov hla ntawm qhov hla loj dua 8 hli bar.

Bar: cov duab ntawm cov hlau puag ncig, hexagonal, square lossis lwm yam hlau ncaj uas muaj duab hla. Hauv cov hlau tsis xeb, cov bar feem ntau yog hais txog feem ntau ntawm cov hlau puag ncig.

 

Cov hlau hlau: mus rau hauv lub disk-puab cross-section ntawm lub voj voog coil, lub cheeb ntawm 5.5 ~ 30 hli. Yog tias tsuas yog hais tias Hlau, hais txog cov hlau hlau, yog rov ua dua los ntawm lub kauj tom qab cov khoom hlau.

Cov pas nrig: kub dov thiab coiled rau hauv ib lub disk rau kev xa cov khoom tiav, suav nrog puag ncig, square, rectangular, hexagonal thiab lwm yam. Txij li thaum feem ntau ntawm puag ncig, yog li ntawd feem ntau hais tias coil yog puag ncig hlau pas nrig coil.

Vim li cas thiaj muaj ntau lub npe? Nov yog qhov kev faib tawm ntawm cov hlau tsim kho

Cov kev faib tawm ntawm cov hlau tsim kho yog dab tsi?

 

Cov khoom lag luam ntawm cov hlau tsim kho feem ntau muab faib ua ntau pawg xws li rebar, hlau puag ncig, hlau xaim, kauj thiab lwm yam.

1, hlau

Feem ntau, cov hlau rebar ntev li ntawm 9m, 12m, thiab cov xov ntev li ntawm 9m feem ntau yog siv rau kev tsim kho txoj kev, thiab cov xov ntev li ntawm 12m feem ntau yog siv rau kev tsim kho choj. Cov lus qhia ntawm cov hlau rebar feem ntau yog 6-50 hli, thiab lub xeev tso cai rau kev hloov pauv. Raws li lub zog, muaj peb hom hlau rebar: HRB335, HRB400 thiab HRB500.

2, hlau puag ncig

Raws li lub npe qhia, cov hlau puag ncig yog cov hlau khov kho uas muaj qhov seem puag ncig, muab faib ua peb hom kub dov, forged thiab txias kos. Muaj ntau cov ntaub ntawv ntawm cov hlau puag ncig, xws li: 10 #, 20 #, 45 #, Q215-235, 42CrMo, 40CrNiMo, GCr15, 3Cr2W8V, 20CrMnTi, 5CrMnMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo thiab lwm yam.

Cov lus qhia tshwj xeeb ntawm cov hlau puag ncig kub rau 5.5-250 hli, 5.5-25 hli yog cov hlau puag ncig me me, cov tuav ncaj nraim muab ua cov pob khoom, siv ua cov tuav txhawb nqa, bolts thiab ntau yam khoom siv kho tshuab; loj dua 25 hli hlau puag ncig, feem ntau yog siv rau hauv kev tsim cov khoom siv kho tshuab lossis rau cov yeeb nkab hlau tsis sib xws.

 

3, Hlau pas nrig

Cov hlau feem ntau muaj peb hom Q195, Q215, Q235, tab sis tsuas yog siv ob hom Q215, Q235 rau kev tsim cov hlau kauj, feem ntau siv cov lus qhia tshwj xeeb uas muaj txoj kab uas hla 6.5 hli, txoj kab uas hla 8.0 hli, thiab txoj kab uas hla 10 hli. Tam sim no, cov kauj loj tshaj plaws hauv Suav teb tuaj yeem muaj txoj kab uas hla txog 30 hli. Ntxiv rau qhov no, hlau kuj siv tau ua cov hlau txhawb nqa rau kev tsim cov hlau txhawb nqa, tab sis kuj siv tau rau cov hlau rau kev kos duab, kev siv hlau los ua cov ntaub thaiv. Cov hlau kuj tseem siv tau rau kev kos duab thiab kev siv hlau los ua cov ntaub thaiv.

 

4, kauj ntsia hlau

Cov hlau kauj zoo li cov hlau uas raug khi ua ke, yog ib hom hlau rau kev tsim kho. Cov hlau kauj siv dav hauv ntau yam qauv tsev, piv rau cov hlau kauj, qhov zoo ntawm cov hlau kauj yog: tsuas yog 9-12 hlau kauj xwb, thiab siv tau raws li qhov xav tau kev cuam tshuam.

 

Kev faib tawm ntawm rebar

Feem ntau raws li cov tshuaj lom neeg muaj pes tsawg leeg, cov txheej txheem tsim khoom, cov duab dov, cov duab muab khoom, qhov loj ntawm lub cheeb, thiab kev siv hlau hauv cov qauv ntawm kev faib tawm:

(1) raws li cov duab dov

① glossy rebar: Qib I rebar (Q235 steel rebar) yog dov rau glossy circular cross-section, daim ntawv muab khoom ntawm disk puag ncig, txoj kab uas hla tsis pub tshaj 10 hli, ntev 6m ~ 12m.
② cov hlau ribbed: peb lub kauv, herringbone thiab crescent-puab, feem ntau Ⅱ, Ⅲ qib hlau dov herringbone, Ⅳ qib hlau dov rau hauv kauv thiab crescent-puab.

③ Hlau hlau (muab faib ua ob hom hlau carbon tsawg thiab hlau carbon) thiab hlau hlua.

④ txias dov twisted hlau bar: txias dov thiab txias twisted rau hauv cov duab.

 

(2) raws li qhov loj ntawm lub cheeb

Hlau hlau (txoj kab uas hla 3 ~ 5 hli),
Cov hlau zoo (txoj kab uas hla 6 ~ 10 hli),
Cov hlau nplaum loj (txoj kab uas hla loj dua 22 hli).
