Tsawg-cov ntsiab Steel hlau no

Hlau ntau lawm yog ib lub hom ntau tshaj, nws txoj kab uas hla ntawm 0.16 ~ 10 hli. Nws swm thiab galvanized cov chaw uas yuav muab faib ua ob yam, los ntawm tus me nyuam raws li txoj cai tau muab faib ua ob tug no yog nqus thiab annealing. Lub zog tensile ntawm no twv steel hlau, siv % 26le; 635 ~ 1000MPa; ntsia thawv yog % 26le; 540 ~ 1320MPa. Loj dua cov hlau taub, tensile zog yog me me thiab. Siv ua tau tensile no twv steel hlau yuav tsum tsis muaj tsawg tshaj li 635MPa. Annealed tus hlau tensile zog ntawm 295 ~ 500MPa. Thaum koj xaiv yam khoom raw, kom cov hlau yooj noj mus ua nyiaj, kom tsis txhob tensile zog kub, hlau taub yuav tsis tshua muaj cov ntsiab lus hauv me; rau qhov loj tus ntsia thawv hlau, koj yuav tsum siv raw cov ntaub ntawv uas muaj cov siab kom tsis txhob muaj hlau dabtsi yog khoov thaum twg cov punch. Thaum lub sijhawm zus tau tej cov du steel hlau rau tus ntsia thawv, qws yuav ua tau txhua yam descaling (saib qws rau txhua yam descaling) thiab muaj txheej (saib daim nyias ev roj nplua nyeem) thiaj yuav xis teb xis chaw. Thaum lub sij hawm ntau lawm los galvanized steel hlau rau tes, vim nws yooj yim dua deg zoo ntawv, feem ntau yog qws tom qab txhua yam descaling los ntawm pickling thiab daj thiab txoj kab dip txheej kho, yuav tau xis teb xis chaw. Vim lub qes-cov steel hlau ntawm yas deformation kuj muaj me me, luaj drawing pulling tsav tag nrho qhov txo (saib qhov txo tus nqi) yuav muab ua loj, thiab yuav txog 95%. Txhua qhov chaw yuav txo tau feem ntau yog tau % 26le; 35%. Tsawg-cov ntsiab steel hlau no galvanized ua ntej kho cua sov los sis extraction txheej txheem ntawm kev kho cua sov intermediate, kheev nruam recrystallization annealing thiab lug siv annealing cua sov thiab cua sov annealing ua ob yam. Nruam annealing thiab nruam zinc kub-dip los sis zinc-plating ua ib kab nruam; cub tawg annealing yog siv rau ib tug lag luam uas tsis yog-nruam ntawm qhov cov kab ntau lawm.
