A572GR50 H Beam

A572GR50 H Beam Products Production Process

Cov txheej txheem tsim khoom ntawm A572GR50 H-beam steel feem ntau suav nrog cov kauj ruam hauv qab no:
Steelmaking: hloov hlau rau hauv cov hlau uas ua tau raws li qhov yuav tsum tau ua los ntawm cov tshuaj tiv thaiv, thiab tswj nws cov tshuaj muaj pes tsawg leeg thiab kub thiab lwm yam tsis.
Nruam casting: cov hlau refined yuav nruam nruam mus rau hauv ib tug tej yam specification ntawm lub billet, los xyuas kom meej lub purity ntawm cov hlau thiab crystallization zoo.
Rolling: Lub billet yog plastically deformed los ntawm dov zeb kom tau qhov yuav tsum tau thickness thiab dav ntawm steel phaj. Nyob rau hauv cov txheej txheem dov, tsis xws li dov kub, dov ceev thiab undercutting yuav tsum tau tswj.
Kev kho cua sov: los ntawm normalizing, tempering thiab lwm yam kev kho cua sov, kom ntxiv dag zog rau cov khoom thiab corrosion kuj ntawm steel phaj.
Lwm yam kev ua: suav nrog kev txiav, ncaj, pab pawg, sawing thiab lwm yam txheej txheem los xyuas kom meej tias qhov loj, qhov zoo thiab qhov zoo ntawm H-beams ua tau raws li qhov yuav tsum tau ua.

A572GR50 H Beam Khoom Cheebtsam

Cov tshuaj muaj pes tsawg leeg ntawm A572GR50 H-beam steel feem ntau suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) thiab niobium (Nb), cov ntsiab lus tshwj xeeb yog raws li hauv qab no:
Carbon (C): Tsawg dua lossis sib npaug li 0.20%
Silicon (Si): Tsawg dua lossis sib npaug li 0.40%
Manganese (Mn): Tsawg dua lossis sib npaug li 1.50%
Phosphorus (P): Tsawg dua lossis sib npaug rau 0.04%
Sulfur (S): Tsawg dua lossis sib npaug rau 0.05
Niobium (Nb): 0.005% - 0.05%
Cov khoom sib xyaw no ua rau A572GR50 H steel muaj lub zog siab thiab zoo weldability thiab toughness, dav siv nyob rau hauv lub tsev steel qauv, siv machinery, mining machinery, tsheb thauj khoom, txuas hniav thiab siab hlab ntsha thiab lwm yam engineering lug.
