Piav Qhia Lub Hom Phiaj thiab Cov Kev Cai
Thaum xaivU-channel hlau, thawj txoj haujlwm yog kom piav qhia meej txog nws qhov kev siv tshwj xeeb thiab cov kev xav tau tseem ceeb:
Qhov no suav nrog kev xam lossis kev soj ntsuam qhov siab tshaj plaws uas nws xav tau los tiv taus (qhov hnyav zoo li qub, qhov hnyav hloov pauv, kev cuam tshuam, thiab lwm yam), uas txiav txim siab ncaj qha rau cov lus qhia thiab qhov ntev (qhov siab, qhov dav ntawm ceg, qhov tuab ntawm lub duav) thiab qib zog ntawm cov khoom siv; nkag siab txog nws cov xwm txheej siv (xws li cov qauv tsev beams / purlins, cov thav duab kho tshuab, cov kab txhawb nqa conveyor, txee lossis kho kom zoo nkauj), cov xwm txheej sib txawv muaj qhov sib txawv ntawm lub zog, kev nruj, kev raug thiab qhov tsos; xav txog qhov chaw siv (sab hauv tsev / sab nraum zoov, seb nws yog av noo, corrosive media), uas txiav txim siab qhov yuav tsum tau tiv thaiv corrosion (xws li kub-dip galvanizing, pleev xim) lossis seb puas xav tau weathering steel / stainless hlau; piav qhia meej txog txoj kev sib txuas (welding lossis bolting), uas yuav cuam tshuam rau kev tsim ceg (qhov chaw vuam tiaj tus lossis qhov chaw khaws cia yog qhov yuav tsum tau ua) thiab cov kev cai rau cov khoom siv weldability; tib lub sijhawm, nws yog qhov tsim nyog los lees paub qhov kev txwv loj ntawm qhov chaw teeb tsa (ntev, qhov siab, dav) thiab cov cai tshwj xeeb lossis cov qauv kev lag luam uas qhov project yuav tsum ua raws li kom ntseeg tau tias cov ntaub ntawv xaiv tau ua tiav txhua qhov kev nyab xeeb thiab kev ua haujlwm.
Cov Lus Qhia Txog U Channel Steel, Qhov Loj thiab Cov Khoom Siv
1. Cov Lus Qhia Tshwj Xeeb
Tus qauv EuropeanUPN channelCov qauv raug muab npe raws li lawv qhov siab ntawm lub duav (chav: mm). Lawv muaj qhov seem ntawm U-puab thiab cov yam ntxwv tseem ceeb suav nrog:
Qhov siab ntawm lub duav (H): Qhov siab tag nrho ntawm cov channel. Piv txwv li, qhov siab ntawm lub duav ntawm UPN240 yog 240 hli.
Qhov dav ntawm txoj hlua (B): Qhov dav ntawm lub flange. Piv txwv li, UPN240 muaj txoj hlua 85 hli.
Qhov tuab ntawm lub duav (d): Qhov tuab ntawm daim ntaub. Piv txwv li, UPN240 muaj qhov tuab ntawm lub duav yog 9.5 hli.
Qhov tuab ntawm cov hlau (t): Qhov tuab ntawm cov hlau. Piv txwv li, UPN240 muaj qhov tuab ntawm cov hlau ntawm 13 hli.
Qhov hnyav theoretical ib 'meter': Qhov hnyav ib chav ntev (kg/m2). Piv txwv li, UPN240 muaj qhov hnyav ntawm 33.2 kg/m2.
Cov Lus Qhia Tshwj Xeeb (Ib Feem Qauv):

| UPN300 | 300 | 100 | 10 | 16 | 46.2 |
| UPN350 | 350 | 100 | 14 | 16 | 60.5 |
2. Hom khoom siv
Cov khoom siv hlau UPN channel yuav tsum ua tau raws li tus qauv European EN 10025-2. Cov kev xaiv feem ntau suav nrog:
(1) Cov ntaub ntawv siv ntau
S235JR: Lub zog tawm los ≥ 235MPa, tus nqi qis, tsim rau cov qauv zoo li qub (xws li kev txhawb nqa lub teeb).
S275JR: Lub zog tawm los ≥ 275MPa, lub zog sib npaug thiab kev lag luam, siv rau cov thav duab tsev dav dav.
S355JR: Lub zog tawm los ≥ 355MPa, thawj qhov kev xaiv rau kev thauj khoom siab, tsim nyog rau cov xwm txheej kev ntxhov siab siab xws li cov tshuab chaw nres nkoj thiab cov choj txhawb nqa. Nws lub zog tensile ncav cuag 470 ~ 630MPa, thiab nws muaj kev tawv zoo thaum kub qis.
(2) Cov ntaub ntawv tshwj xeeb
Cov hlau muaj zog siab: xws li S420 / S460, siv rau cov khoom siv fais fab nuclear thiab cov tshuab hnyav heev (xws li UPN350).
Cov hlau uas tiv taus huab cua: xws li S355J0W, tiv taus kev xeb hauv huab cua, tsim nyog rau cov choj sab nraum zoov.
Hlau tsis xeb: siv rau hauv cov chaw muaj xeb xws li tshuaj lom neeg thiab dej hiav txwv, tab sis nrog tus nqi siab dua.
(3) Kev kho qhov chaw
Kub-dov dub: qhov chaw qub, xav tau kev kho mob tiv thaiv xeb tom qab.
Kub-dip galvanizing: galvanized txheej ≥ 60μm (xws li channel steel rau cov yeeb nkab gallery txhawb nqa), txhim kho kev tiv thaiv corrosion.
3. Cov lus qhia xaiv
Cov xwm txheej thauj khoom ntau (xws li cov hlau crane chaw nres nkoj): Muab qhov tseem ceeb rau cov ntaub ntawv UPN300 ~ UPN350 + S355JR kom ntseeg tau tias muaj kev tiv taus khoov thiab shear.
Ib puag ncig xeb: Ua ke nrog kub-dip galvanizing lossis ncaj qha siv weathering hlau.
Qhov yuav tsum tau hnav khaub ncaws hnyav: UPN80 ~ UPN120 series (meter qhov hnyav 8.6 ~ 13.4kg / m), tsim nyog rau cov keels phab ntsa thiab cov yeeb nkab txhawb nqa.
Lus Cim: Thaum yuav khoom, nws yog ib qho tsim nyog los xyuas cov ntaub ntawv qhia txog cov khoom siv (raws li EN 10025-2) thiab qhov ntev ntawm kev kam rau siab (EN 10060) kom ntseeg tau tias qhov project ua raws li qhov project.
