Q: Q235 coils puas tuaj yeem siv nyob rau hauv qis - qhov kub thiab txias?
A: Q235D tuaj yeem siv ntawm -20 degree; Qib B / C tsis pom zoo rau sab nraum zoov dynamic load qauv ntawm tsawg dua los yog sib npaug rau -10 degree, thiab qib D los yog weathering steel yuav tsum nyiam.
Q: Puas Q235 coils hloov Q355 coils?
A: Feem ntau tsis yog. Q355 muaj lub zog tawm los Ntau dua lossis sib npaug ntawm 355MPa, lub zog siab dua; Cov txheej txheem kev ntxhov siab yuav tsum raug xam, thiab nws tsuas yog hloov tau raws li qee qhov xwm txheej rau qhov me me thiab qis - cov xwm txheej kev ntxhov siab nyob rau hauv cov khoom zoo li qub.
Q: Dab tsi yog txoj kev kho saum npoo rau Q235 coils?
A: Feem ntau siv cov txheej txheem xws li galvanizing (kub-dip/electroplated zinc), xim txheej, tshuaj pleev xim, thiab passivation; cov no txhim kho corrosion kuj thiab hloov mus rau ntau yam kev ua haujlwm.
Q: Dab tsi yog qhov tsis xws luag ntawm Q235 coils?
A: Hlau oxide nplai, khawb, indentations, ntug kab nrib pleb, transverse creases, inclusions, waviness, thiab warping, feem ntau hais txog raw cov ntaub ntawv, dov txheej txheem, los yog tiav theem.
Q: Dab tsi yog qhov tshwm sim thiab kev daws teeb meem rau kev hla -folding defects hauv Q235 coils? A: Feem ntau tshwm sim nyob rau hauv thicknesses ntawm 3.0-6.0 hli, tshwj xeeb tshaj yog 5.5-6.0 hli. Kev daws: Ua kom qhov kawg dov kub mus rau 870 degree, tswj cov yas kom tsawg dua los yog sib npaug ntawm 60μm, kho cov coiling kub rau 580 degree, thiab txhim kho cov txheej txheem dov thiab txias.
