Q: Puas yog Q235 steel haum rau scaffolding thiab formwork txhawb?
A: Yog, nws tsim nyog. Q235 welded kav los yog lub kaum sab xis hlau feem ntau yog siv, tab sis phab ntsa thickness thiab erection specifications yuav tsum nruj me ntsis tswj.
Q: Cov ntaub ntawv dab tsi yuav tsum tau kuaj xyuas thaum Q235 steel tuaj txog ntawm qhov chaw?
A: Daim ntawv pov thawj zoo (lub tshuab hluav taws xob batch tooj, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab), daim ntawv pov thawj ntawm kev ua raws, kev qhia tshwj xeeb, thiab cov qhab nia qib.
Q: Dab tsi yog batch thiab cov khoom yuav tsum tau rau Q235 steel re- tshuaj xyuas thaum tuaj txog?
A: Rau tib qib, rauv batch tooj, thiab specifications, txhua batch yuav tsum yog 60 tons; tsawg dua 60 tons yog suav tias yog ib pawg. Cov cuab yeej siv tshuab (yield zog, tensile zog, elongation) yuav tsum tau rov kuaj dua -. Kev ntsuam xyuas cuam tshuam yuav tsum tau ua yog tias yuav tsum muaj kev cuam tshuam; rau Z-kev taw qhia steel, txo qhov chaw yuav tsum tau sim.
Q: Dab tsi yog qhov tsis xws luag ntawm Q235 steel thiab lawv cov qauv txiav txim?
A: Feem ntau muaj xws li khawb, pitting, xeb, thiab quav. Hlau nrog qhov tob tsis tshaj qhov tsis zoo thickness sib txawv thiab tsis cuam tshuam rau cov qauv kev nyab xeeb tuaj yeem siv tau; tawg thiab delamination raug txwv nruj heev.
Q: Yuav ua li cas paub qhov txawv Q235 los ntawm lwm cov hlau (xws li Q355)?
A: Tshawb xyuas daim ntawv pov thawj zoo, ua spectral tsom xam ntawm cov tshuaj muaj pes tsawg leeg, thiab ua cov cuab yeej cuab tam ntawm cov qauv kom tsis txhob sib tov.
