Q235 structural steel lub kaum sab xis hlau, cov khoom siv tseem ceeb hauv kev lag luam carbon steel fabrication, yog tsim thiab tsim kom tau raws li cov qauv kev ua tau zoo nyob thoob plaws ntau hom kev lag luam thiab kev tsim kho. Raws li cov pa roj carbon steel bar nrog lub kaum ntse ntse hla- ntu (feem ntau muaj qhov sib npaug lossis tsis sib npaug ntawm ceg ntev), cov khoom no yog txhais los ntawm nws cov khoom siv hauv paus -Q235 carbon steel, dav lees paub thiab siv dav siv qis- qib carbon steel muaj npe nrov rau nws cov khoom sib npaug thiab cov nqi siv tau zoo- zoo
Cov txheej txheem tsim khoom ntawm Q235 cov txheej txheem steel lub kaum ntse ntse ua raws li cov qauv kev lag luam nruj, ua kom ntseeg tau zoo thiab muaj kev ntseeg siab. Nws pib nrog kev xaiv ntawm siab -purity Q235 carbon steel billets, uas tau dhau los ua cua sov hauv lub qhov cub tswj kom ua tiav qhov zoo tshaj plaws rau kev tsim. Tom ntej no kub dov yog lub hauv paus tsim cov kauj ruam: cov rhuab billets yog dhau los ntawm ib tug series ntawm calibrated dov mills, uas maj mam muab cov khoom rau hauv tus yam ntxwv L-zoo li tus ntoo khaub lig-section. Cov txheej txheem kub no - dov tsis yog tsuas yog kho cov qauv ntawm cov hlau, tab sis kuj txhim kho nws lub zog tensile thiab kev ncaj ncees. Tom qab- dov, lub kaum sab xis hlau txuas ncaj qha, txiav mus rau qhov ntev, thiab kho qhov chaw (xws li pickling lossis galvanizing, nyob ntawm daim ntawv thov) kom tshem tawm cov nplais oxide thiab txhim kho corrosion.
Hais txog cov khoom siv, Q235 carbon steel nthuav tawm qhov tsawg kawg nkaus lub zog ntawm 235 MPa, lub zog tensile xws li 375 txog 500 MPa, thiab zoo heev weldability thiab formability. Cov cwj pwm no ua rau Q235 cov txheej txheem steel lub kaum ntse ntse hlau muaj ntau yam rau kev thauj khoom -cov kabmob thiab kev siv bracing. Nws yog feem ntau siv rau hauv kev tsim cov steel ncej rau cov tsev, txuas hniav, thiab warehouses, raws li zoo raws li nyob rau hauv lub fabrication ntawm machinery thav duab, txhawb brackets, shipping ntim, thiab kis tau tus yees. Tsis tas li ntawd, nws cov nqi-kev ua tau zoo ua ke nrog kev ua tau zoo txhim khu kev qha ua rau nws qhov kev xaiv zoo tshaj plaws rau ob qho tib si kev lag luam thiab kev tsim kho vaj tse.
Peb Q235 cov txheej txheem steel lub kaum sab xis hlau tsim tau raug lees paub rau cov qauv thoob ntiaj teb (xws li GB / T 706-2016 thiab ASTM A36), kom ntseeg tau tias txhua yam khoom ua tau raws li qhov ua tau zoo ntawm qhov ntev thiab cov qauv kev ua haujlwm. Peb muab ntau yam kev qhia tshwj xeeb, suav nrog cov kaum sab xis sib npaug (piv txwv li, 20 × 20 × 3 mm txog 200 × 200 × 24 mm) thiab cov kaum sab xis tsis sib xws, tuaj yeem hloov kho kom haum rau cov phiaj xwm tshwj xeeb. Nrog rau cov khoom siv ntau lawm thiab kev tswj xyuas nruj, peb lav qhov kev xa khoom zoo ntawm Q235 cov qauv steel lub kaum sab xis uas muab kev ruaj ntseg thiab ruaj khov kev txhawb nqa rau ntau yam kev siv.
