Dab tsi yog cov ntawv thov ntawm Q235 steel coils hauv kev tsim kho hauv nroog?
A: Lawv yog siv rau hauv nroog txhawb nqa steel qauv xws li txoj kev teeb ncej, tsheb ciav hlau teeb meem, underground yeeb nkab gallery kev txhawb nqa, thiab cov khoom siv kho dej phwj hauv vaj tse.
Yuav ua li cas Q235 steel coil qib yuav raug xaiv rau cov tsev nyob hauv qis- qhov kub thiab txias?
A: Rau qhov kub siab tshaj -20 degree, xaiv Q235C; rau qhov kub thiab txias tsawg dua los yog sib npaug rau -20 degree, xaiv Q235D kom ntseeg tau tias qhov kub thiab txias cuam tshuam tsis zoo thiab tsis txhob tawg tawg.
Q235 steel coils puas tuaj yeem siv rau hauv hluav taws kub -cov khoom tiv thaiv lub tsev?
A: Lawv tsis yog hluav taws kub- tiv taus lawv tus kheej thiab yuav tsum tau hluav taws kub- cov txheej txheej / npog kom ua tau raws li kev tiv thaiv hluav taws hauv tsev (piv txwv li, qhov ntsuas hluav taws kub 1-3 teev).
Dab tsi yog cov khoom txais rau Q235 steel coils thaum tuaj txog ntawm qhov chaw tsim kho?
A: Tshawb xyuas daim ntawv pov thawj zoo (qib, qib, cov khoom siv hluav taws xob / tshuaj lom neeg); kev soj ntsuam pom (tsis muaj kab nrib pleb, xeb, pitting); re- ntsuas qhov ntev (thickness, dav, flatness); qauv rau tensile, txias dabtsi yog khoov, thiab tej yam kev kuaj (raws li specifications).
Dab tsi yog qhov tsis zoo ntawm Q235 steel coils thiab lawv qhov cuam tshuam rau lub tsev? A: Corrosion (txo cov load-cov kabmob muaj peev xwm thiab cuam tshuam rau vuam); tsis sib luag thickness (kev ntxhov siab tsis sib xws ntawm cov khoom); ntug kab nrib pleb (kev ua cov kab nrib pleb, kev phom sij); inclusions (vuam tawg, substandard mechanical zog).
