Q1: Q460 welded kav puas tuaj yeem siv rau hauv qhov chaw siab - qhov kub thiab txias, thiab qhov kev pabcuam siab tshaj plaws yog qhov pom zoo?
A1:Q460 tsis yog tsim los rau kev ua haujlwm siab - qhov kub thiab txias. Nws cov khoom siv tshuab pib degrade ntawm qhov kub thiab txias saum toj no300 degree. Rau siab- cov ntawv thov kub (xws li, cov tshuab hluav taws xob, cov chaw tsim hluav taws xob), cov cua sov- cov qib siab resistant alloy nrog chromium (Cr) thiab molybdenum (Mo) ntxiv yuav raug teev tseg. Q460 yog qhov zoo tshaj plaws rau ambient mus rau ib puag ncig sov.
Q2: Cov txheej txheem kev tsim khoom zoo li cas yog siv los tsim cov siab -precision Q460 welded kav rau aerospace thiab siab - kev tsheb ciav hlau ceev?
A2:Rau cov kev siv ultra-precision no,Laser VuamthiabUltra-High Frequency Vuamsiv. Cov tswv yim no muab cov tswv yim cua sov tsawg thiab kev tswj xyuas meej, ua rau HAZ nqaim heev thiab tshwj xeeb weld zoo. Cov kav dej feem ntau raug kuaj xyuas nruj kom ntseeg tau tias tsis muaj micro- tsis xws luag uas tuaj yeem cuam tshuam kev nyab xeeb.
Q3: Hauv kev tsim seismic, Q460 welded yeeb nkab ua haujlwm li cas rau lub tsev av qeeg, dhau ntawm lub zog siab?
A3:Tshaj li lub zog siab, Q460 muaj qhov zoo heevzog dissipation muaj peev xwmvim nws high ductility. Thaum lub sij hawm muaj av qeeg, cov yeeb nkab steel tau txais cov yas deformation, absorbing thiab dissipating seismic zog. Qhov no tiv thaiv lub tsev tsis txhob tawg. Thaum ua ke nrog kev tsim kom zoo, Q460 cov qauv tuaj yeem ua tiav qib siab seismic kev ua tau zoo (piv txwv li, Kev Nyob Tam Sim No lossis Kev Nyab Xeeb Lub Neej).
Q4: Dab tsi yog cov qauv muab qhab nia rau Q460 welded kav xa tawm mus rau European thiab North American kev lag luam?
A4:Rau kev xa tawm, Q460 feem ntau sib npaug rau cov qauv European zoo liS460 NL(tsis yog- thauj khoom los ntawm- tuab) lossisS460M(normalized). Hauv North America, nws sib haum rauASTM A992 Cov Lus Qhia Tshwj Xeeb(ib hom qauv hlau) los yogASTM A572 Qib 65. Thaum sib txuas lus nrog cov neeg siv khoom thoob ntiaj teb, nws yog ib qho tseem ceeb rau kev siv cov qib sib npaug nrog rau Suav GB tus qauv.
Q5: Yuav ua li cas ib tug yuav tsum txhais cov ntaub ntawv ntsuam xyuas cov ntaub ntawv (MTR) rau ib batch ntawm Q460 welded kav los xyuas kom meej raws li specifications?
A5:MTR siv tau yuav tsum muaj xws li: Daim ntawv pov thawj, tus naj npawb cua sov, tshuaj ntsuam xyuas (C, Mn, P, S, V, Nb), cov khoom siv hluav taws xob (yield zog, tensile zog, elongation, cuam tshuam toughness ntawm -20℃lossis teev temp), thiab cov ntsiab lus kho cua sov. Xyuas kom tseeb tias lub zog tawm los yog ntau dua los yog sib npaug rau 460 MPa thiab qhov cuam tshuam toughness qhov tseem ceeb ua tau raws li qhov xav tau yam tsawg kawg nkaus (feem ntau Ntau dua lossis sib npaug rau 27 J ntawm -40℃rau qib siab toughness).
