Q1: Dab tsi yog cov teeb meem hauv kev khaws cia Q460 welded kav rau lub sij hawm ntev, thiab cov kev cia siab dab tsi tau pom zoo?
A1:Qhov kev sib tw tseem ceeb yog corrosion, tshwj xeeb tshaj yog nyob rau hauv cov av noo los yog saline ib puag ncig. Cov kav dej yuav tsum tau muab cia rau hauv aqhuav, zoo -ventilated warehousentawm cov ntoo pallets los tiv thaiv kev sib cuag nrog cov av ntub dej. Lawv yuav tsum tau them nrog waterproof tarpaulins. Rau ntev - lub sij hawm cia (tshaj 6 lub hlis), kub -dip galvanizing los yog xeb- tiv thaiv roj txheej yog pom zoo.
Q2: Nyob rau hauv lub tshav pob ntawm kev thauj mus los, qhov zoo ntawm kev siv Q460 kauv welded kav hla ncaj seam welded kav?
A2:Kauv welded kav muab kev yooj yim dua hauv kev tsim thiab tuaj yeem ua kom haum cov kab loj dua thiab cov phab ntsa tuab. Lub kauv seam faib kev ntxhov siab ntau dua ib ncig ntawm cov yeeb nkab, ua rau nws tiv taus ntau dua rau sab hauv siab thiab sab nraud dabtsi yog khoov quab yuam. Q460 kauv cov kav dej feem ntau yog qhov kev xaiv zoo rau ntev - cov roj av thiab cov roj nkev cov kav dej uas muaj kev kub ntxhov yog qhov tseem ceeb.
Q3: Tus cwj pwm nkag ntawm Q460 welded yeeb nkab cuam tshuam li cas rau nws lub sijhawm ntev - kev ua tau zoo hauv lub tshuab hluav taws xob cog dej txias?
A3:Creep yog qhov qeeb deformation nyob rau hauv qhov kev ntxhov siab tas li ntawm qhov kub thiab txias. Q460 muaj qhov zoo ntawm kev nkag mus txog 300 degree, uas yog qhov zoo rau cov dej txias. Txawm li cas los xij, ntawm qhov kub siab tshaj qhov no, creep deformation tuaj yeem tshwm sim, ua rau cov yeeb nkab elongation thiab muaj peev xwm ua tsis tiav. Kev tshuaj xyuas tsis tu ncua rau phab ntsa thinning yog qhov tseem ceeb rau kev ua haujlwm ntev -.
Q4: Rau ib txoj haujlwm kev cai uas xav tau Q460 welded kav uas tsis yog - qauv phab ntsa thickness, dab tsi kev sib txuas lus yog tsim nyog nrog cov chaw tsim tshuaj paus?
A4:Koj yuav tsum muab cov ntaub ntawv qhia ntxaws ntxaws, suav nrog cov kab sib txawv, phab ntsa thickness kam rau ua (piv txwv li, ± 0.5mm), ntev ntev (random lossis tsau), qhov kawg xov (beveled, tiaj), thiab yuav tsum tau txheej txheej. Nws tseem yog ib qho tseem ceeb kom qhia meej txog cov txheej txheem vuam (HFW, SAW) thiab ib qho yuav tsum tsis yog -kev ntsuas kev puas tsuaj (NDT) kom ntseeg tau tias cov chaw tsim khoom tuaj yeem tsim cov kav dej raws li koj qhov tshwj xeeb.
Q5: Yuav ua li cas rau yav tom ntej tiam ntawm steel technology yuav cuam tshuam rau txoj kev loj hlob thiab daim ntawv thov ntawm Q460 welded kav?
A5:Cov qauv tseem ceeb suav nrogmicroalloying optimizationlos txhim kho lub zog thiab toughness ntawm tus nqi qis, kev txhim kho ntawmQ460 nrog txhim kho corrosion kuj(piv txwv li, weathering steel qib), thiab kev koom ua ke ntawmntse manufacturinglos xyuas kom meej qhov zoo. Tsis tas li ntawd, raws li kev xav tau thoob ntiaj teb kev tsim kho vaj tse loj hlob, Q460 yuav zoo li yuav ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg, siab - kev tsim kho thiab kev lag luam.
