Cov khoom siv raw ntawmtxias dov steel kaujyog cov khoom zoo kub dov, thiab tom qab pickling nruam dov, degreasing, annealing, daim tawv nqaij dhau, slitting thiab txiav mus rau ntev kab thiab lwm yam.
Ua ntej, kub dov steel coils yog siv los ua raw khoom, oxide zaj duab xis raug tshem tawm nrog pickling thiab annealing. Thaum lub sij hawm tus txheej txheem no, lub hardness ntawm kub dov coils yog txo, thiab cov kev ua tau zoo ntawm steel yog zoo dua. Muaj ob hom kev kho annealing, ib qho yog Tswb-hom annealing rauv ua kom ci steel coils, lwm qhov yog Nruam Annealing rauv ua cov hlau dub.
Kub-dipped Galvanized Steel Chev
Dab tsi yog cov txiaj ntsig ntawm kub-kuav los tiag steel?
Kub dov hlau feem ntau yuav tsum tau ua tsawg dua li cov hlau txias, uas ua rau nws pheej yig dua. Vim tias cov hlau kub-dov tuaj yeem ua kom txias ntawm chav tsev kub, nws yog qhov tseem ceeb normalized - lub ntsiab lus tias nws tsis muaj kev ntxhov siab sab hauv uas tuaj yeem tshwm sim los ntawm cov txheej txheem hardening lossis work hardening.
Kub-dov hlau yog qhov zoo tshaj plaws uas qhov ntev ntev yog qhov tseem ceeb dua li cov khoom siv tag nrho lub zog thiab qhov ua tiav saum npoo tsis yog qhov teeb meem tseem ceeb. Yog tias qhov ua tiav saum npoo yog qhov teeb meem, nplai tuaj yeem raug tshem tawm los ntawm kev sib tsoo, sandblasting lossis pickling hauv cov kua qaub da dej. Thaum cov nplai tau raug tshem tawm, ntau yam txhuam los yog daim iav tiav tuaj yeem siv tau. Descaled steel kuj muab qhov chaw zoo dua rau cov xim thiab lwm yam txheej txheej.
Cov txiaj ntsig ntawm txias dov steel yog dab tsi?
Cold-dov hlau muaj cov yam ntxwv zoo dua li cov hlau kub dov, yog li nws tsis yog qhov xav tsis thoob tias cov hlau txias-kuav los tiag yog feem ntau siv rau kev siv cov ntaub ntawv ntau dua los yog cov ntawv thov uas qhov kev zoo nkauj tseem ceeb. Txawm li cas los xij, lawv kim dua vim qhov ua tiav ntawm cov khoom txias tiav.

Qhov no yuav zoo li pom tseeb, tab sis qee hom hlau zoo dua rau qee yam kev siv. Paub qhov twg siv yuav pab kom tsis txhob overspending ntawm raw khoom. Nws tseem tuaj yeem txuag lub sijhawm thiab nyiaj txiag ntawm kev tuav ntxiv. Kev nkag siab txog qhov sib txawv ntawm cov hlau kub thiab txias yog qhov tseem ceeb rau kev xaiv ib lossis lwm qhov.
Cold Rolled Steel Coils; bsp;
Nyob rau hauv cov nqe lus ntawm lub cev muaj zog, txias-kuav los tiag steel feem ntau yog ib qho nyuaj thiab muaj zog tshaj tus qauv kub-kuav los tiag steel. Raws li cov hlau yog tsim los ntawm qhov kub thiab txias, qhov hardness, tensile tawg tsis kam thiab deformation kuj ntawm cov hlau yog tag nrho nce los ntawm kev ua hauj lwm hardening.
Txawm li cas los xij, cov kev kho mob ntxiv no tuaj yeem tsim kev ntxhov siab sab hauv hauv cov khoom siv. Qhov no tuaj yeem ua rau tsis muaj kev phom sij yog tias cov hlau tsis muaj kev ntxhov siab ua ntej txiav, sib tsoo lossis vuam.
Manufacturing thiab cov khoom tsim
Nyob ntawm seb koj tab tom tsim dab tsi, cov khoom sib txawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Rau cov haujlwm dav dav lossis kev tsim tawm ib zaug, cov khoom siv hlau tuaj yeem muab cov tsev thaiv rau txhua qhov kev tsim qauv tsim.
