Q235 Cov Pa Roj Carbon phaj nruj me ntsis ua raws li cov khoom siv A36 tsawg dua lossis muaj sib npaug tsawg dua lossis sib npaug ntawm 0.035% 0.045%): Lub zog tensile lub zog 400-550 mpa (ntsuas hluav taws xob tsawg dua los yog sib npaug nrog 0.37% kom ua tau zoo heev weldability.
Nyob rau hauv ib puag ncig qhuav ntawm chav tsev kub, nws cov kev pabcuam lub neej tuaj yeem hloov tau ntau dua 10 xyoo (nyob rau hauv ib qho chaw muaj zog ntawm cov neeg siv khoom muaj zog 4 xyoos
Kev Ua Hoobkas
Sandblasting thiab Painting Kev Kho Mob Yog muab. Qhov saum npoo roughness ra tom qab sandblasting yog nruab nrab ntawm 40-80μm, uas tau ntsib rau SSPC-SP 10 tus qauv. Cov xim tuab yog ib yam nkaus, cov yeeb yaj kiab qhuav tuab mus txog 80-120μm, thiab cov adhesion qib nce mus txog 5b hauv Astm D3359. Kev txiav txim ntshav txiav ntshav tsis muaj peev xwm ua tau, thiab kev txiav kev thev taus yog tsawg dua li 1mm / 3M, uas tuaj yeem ntsib cov qhua tuaj noj mov kom muaj ntau yam rau phaj loj.
Ntau lawm lub zog
Cov txheej txheem smelting advts advts ua kom zoo dua (nitrogen cov ntsiab lus tsawg dua lossis sib npaug nrog 80pppm), nruab nrog rau 80pppM), nruab
Lub peev txheej txhua xyoo tau nce mus txog 30,000 tons, uas yog qib coj ntawm cov chaw ua haujlwm zoo sib xws hauv lub ntiaj teb. Ntawm lawv, tsis muaj ntau tshaj 10 lub chaw ua haujlwm uas tuaj yeem ua rau loj loj tau loj dua lossis sib npaug rau 20,000 tons; 500 tons ntawm cov lus nug xim, npog cov lus qhia tshwj xeeb xws li 3mm / 6mm / 6mm / 6mm / 10mm (cov khoom muag tuaj yeem ua kom muaj kev ua kom dhau los ntawm cov kab ke online).
Txhua cov khoom ntawm cov khoom undergoes tensile kuaj (raws li hardness ntsuas (brinell hardness (brinell hardness (brinell hardness (brinell hardness (brinell hardness hbw 130-170) kom ntseeg tau tias cov khoom ua tau raws cov qauv.
Tuam Txhab Koom Tes
Ib-zaug xaj ntawm 50 tons thiab saum toj no tuaj yeem txaus siab txog 8% luv nqi thiab kev ua kom ua kev pabcuam ua ntej. Peb tau lees tias yog tias cov khoom siv tshuab ntawm Q235 Cov Qauv Hlau Tsis tuaj yeem ntsib cov ASTM A36 tus qauv, lossis tsis muaj kev ua yeeb yam tsis zoo nyob rau hauv ib puag ncig ib puag ncig, peb yuav them nyiaj puv nkaus.
