Qhia meej lub hom phiaj thiab xav tau
Thaum xaivU-channel hlau, thawj txoj haujlwm yog los qhia meej txog nws cov kev siv tshwj xeeb thiab cov ntsiab lus tseem ceeb:
Qhov no suav nrog kev suav kom raug lossis ntsuas qhov siab tshaj plaws uas nws xav tau los tiv thaiv (zoo li qub load, dynamic load, cuam tshuam, thiab lwm yam), uas ncaj qha txiav txim siab qhov tshwj xeeb thiab qhov ntev (qhov siab, ceg dav, duav thickness) thiab cov khoom siv zog qib; nkag siab txog nws daim ntawv thov scenarios (xws li lub tsev qauv kab teeb / purlins, mechanical thav duab, conveyor kab kev txhawb nqa, rhawv lossis kho kom zoo nkauj), cov xwm txheej sib txawv muaj qhov sib txawv ntawm lub zog, rigidity, precision thiab tsos; xav txog kev siv ib puag ncig (sab hauv tsev / sab nraum zoov, txawm tias nws ntub, corrosive media), uas txiav txim siab txog kev tiv thaiv corrosion (xws li kub-dip galvanizing, pleev xim) lossis seb huab cua yuav tsum muaj hlau / stainless hlau; qhia meej txog txoj kev sib txuas (vuam lossis bolting), uas yuav cuam tshuam rau cov ceg tsim (xws li vuam nto los yog qhov tshwj xeeb yuav tsum tau) thiab cov kev cai rau cov khoom siv weldability; Nyob rau tib lub sijhawm, nws yuav tsum tau lees paub qhov kev txwv loj ntawm qhov chaw teeb tsa (ntev, qhov siab, dav) thiab cov kev cai tshwj xeeb lossis cov qauv kev lag luam uas lub phiaj xwm yuav tsum ua raws li kom ntseeg tau tias cov ntaub ntawv xaiv tau raws li txhua yam kev nyab xeeb thiab kev ua haujlwm.
U Channel Steel Specifications, qhov ntev thiab cov khoom siv
1. Cov lus qhia tshwj xeeb
European txheemUPN channelcov qauv muaj npe tom qab lawv lub duav qhov siab (unit: mm). Lawv muaj U-shaped cross-section thiab cov ntsiab lus tseem ceeb suav nrog:
Lub duav qhov siab (H): Qhov siab tag nrho ntawm cov channel. Piv txwv li, lub duav siab ntawm UPN240 yog 240 mm.

2. Hom khoom
UPN channel steel khoom yuav tsum ua tau raws li European tus qauv EN 10025-2. Cov kev xaiv uas muaj xws li:
(1) Cov khoom siv
S235JR: Yield zog ≥ 235MPa, tus nqi qis, haum rau cov qauv zoo li qub (xws li kev txhawb nqa lub teeb).
S275JR: Yield zog ≥ 275MPa, sib npaug lub zog thiab kev lag luam, siv rau kev tsim vaj tsev dav dav.
S355JR: Yield zog ≥ 355MPa, thawj qhov kev xaiv rau kev thauj khoom siab, haum rau cov xwm txheej ntxhov siab xws li chaw nres nkoj tshuab thiab kev txhawb nqa choj. Nws lub zog tensile ncav cuag 470 ~ 630MPa, thiab nws muaj qhov kub tsis tshua muaj zog.
(2) Cov ntaub ntawv tshwj xeeb
Lub zog muaj zog hlau: xws li S420 / S460, siv rau cov cuab yeej siv hluav taws xob nuclear thiab cov tshuab ua haujlwm hnyav heev (xws li UPN350).
Huab cua hlau: xws li S355J0W, tiv taus atmospheric corrosion, haum rau sab nraum zoov txuas hniav.
Stainless hlau: siv nyob rau hauv corrosive ib puag ncig xws li tshuaj thiab marine, tab sis nrog tus nqi siab dua.
(3) Kev kho deg
Kub-dub dov dub: lub neej ntawd nto, yuav tsum tau tom qab los tiv thaiv corrosion.
Kub-dip galvanizing: galvanized txheej ≥ 60μm (xws li channel steel rau cov yeeb nkab gallery txhawb nqa), txhim kho corrosion kuj.
3. Cov lus pom zoo xaiv
High-load scenarios (xws li chaw nres nkoj crane ntsia): Ua ntej UPN300 ~ UPN350 + S355JR cov ntaub ntawv kom ntseeg tau tias khoov thiab shear tsis kam.
Corrosive ib puag ncig: Ua ke nrog kub-dip galvanizing lossis ncaj qha siv huab cua steel.
Cov kev xav tau sib sib zog nqus: UPN80 ~ UPN120 series (meter hnyav 8.6 ~ 13.4kg / m), haum rau cov ntaub thaiv phab ntsa keels thiab cov yeeb nkab txhawb nqa.
Nco tseg: Thaum yuav khoom, nws yuav tsum tau txheeb xyuas cov ntaub ntawv qhia (raws li EN 10025-2) thiab qhov ntev ntev (EN 10060) kom ntseeg tau tias kev ua raws li qhov project.
