1.What yog lub ntsiab lus ntawm kub yob menyuam?
Cov khoom siv hauv paus (Q345B steel phaj) yog pickled thiab kub- dip galvanized ncaj qha tom qab kub qhuav yob lossis analaling. Nws cov xwm txheej raug cim tau cim raws li "kub dov + kub- dip galvanized" (Electrogalvanizing tsis tshua siv kub- dov cov khoom). Qhov kub - Rolled cov khoom siv muaj microstructure ntawm "Ferrite + mov nplaum (20-40μm). Txawm li cas los xij, tswj tau laminar txias tom qab kub dov kom ntseeg tau tias nws cov khoom siv neeg ua tau raws li Q345B txheem.
2.Qhov dab tsi yog cov yam ntxwv ntawm kub - rolled tus me nyuam?
Thickness ntau: feem ntau nruab nrab - tuab}}} 12 2}} 12.0mm (kub-dov yog qhov nyuaj los tsim thinner substrates).
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Tshaj Tawm Lub Zog 355Mpa, Tensile Lub Zog 470 {} 620mpa. Kev tawv me me dua qis dua-rolled (kev cuam tshuam lub zog 34-38j), tab sis lub zog ruaj khov haum rau load-cov kabmob.
Cov Khoom Zoo: Cov me me ntawm oxidation tej zaum yuav muaj (tshem tawm los ntawm pickling). Tom qab galvanizing, saum npoo muaj ib tus neeg muaj kub - dip galvanized matte tiav nrog tsis muaj cov glossable.
3.Qhov dab tsi yog cov lus txhais ntawm cov khoom txias xa cov xwm txheej?
Cov khoom siv hauv paus (Q345B steel phaj) yog thawj kub {}}}}}}}}}}}}} 3.0mm). Thaum kawg, nws undergoes pickling thiab galvanizing (kub- dip lossis electroplating). Cov xwm txheej xa tawm yog cim tias "Txias Rolled + kub- dip galvanized / electroplated galvanized / electroplated galvanized /" Cov txheej txheem txias txias uas tsim "ua haujlwm txias ua haujlwm hnyav" (lis kev ua kom zoo rau 10 - 20μm). Qee cov khoom lag luam yauv rov ua dua cov recrystallization analing (kom tshem tawm sab hauv kev ntxhov siab thiab txhim kho kev ntxhov siab hauv sab hauv). Yog li ntawd, tus txias - rolled lub xeev tuaj yeem muab faib ntxiv rau hauv "txias} {rolled hardeded (CR-a)."
4.Qhov dab tsi yog cov yam ntxwv ntawm cov khoom xa tuaj txias?
Thickness ntau: 0.2-3.0 hli tshuab ntsuas ntshav nrog siv lub zog tsis muaj tseeb (± 0.05 hli), tiaj tus lej (cov duab npe sib luag lossis sib luag ntawm 3 hli / m);
Cov Khoom Siv Neeg Kho Tshuab:
Txias -}}} Lub zog 370-380MPA (txias ua haujlwm hnyav ntxiv tau lub zog)
Txias -} polled annealed: tawm lub zog 34% -25%, thiab txhim kho cov txheej txheem sib txawv xws li cua txias thiab stamping;
Cov Khoom Zoo: Tus txias txias - rolled substrate muaj qhov kaj nyiaj, tshwj xeeb yog cov hluav taws xob zoo nkauj nrog cov xim loj thiab tsis muaj qhov tseeb.
5.Qhov yog qhov anealing cov xwm txheej kev lig kev cai txhais thiab cov txheej txheem logic?
Txhawm rau hais txog kev ntxhov siab rau sab hauv kev ntxhov siab thiab tsis muaj zog} Lub xeev tus me nyuam yog cim raws li "txias - rolled annaling + galvanizing." Lub xeev no yog qhov tseem ceeb ib qho zoo version ntawm lub xeev txias-dov. Cov lus tseem ceeb ntawm cov lus dag hauv kev txo cov kev ntxhov siab sab hauv thiab txhim kho kev muaj kev txhim kho sab hauv los ntawm annealing, es hloov pauv hom substrate.
