Cold-dov coils yog ua los ntawm kub dov coils, uas yog dov nyob rau hauv chav tsev kub hauv qab lub recrystallization kub, nrog rau cov phaj thiab coils. Ntau lub tsev steel mills xws li Baosteel, Wuhan Hlau thiab Hlau, thiab Anshan Hlau thiab Hlau tuaj yeem tsim lawv. Ntawm lawv, cov khoom xa tuaj hauv cov ntawv yog hu ua steel daim hlau, tseem hu ua lub thawv ntawv lossis daim hlau tiaj tus; cov xa hauv yob yog hu ua steel strips, tseem hu ua coil plates. Lub ntsiab txhais ntawm txias dov yog dov nyob rau hauv recrystallization, tab sis nws yog feem ntau to taub raws li dov siv ib txwm kub dov cov ntaub ntawv. Aluminium txias dov yog muab faib ua phaj dov thiab ntawv ci dov. Cov tuab ntawm 0.15 ~ lossis ntau dua yog hu ua daim hlau, thiab cov tuab ntawm 0.15 ~ lossis tsawg dua yog hu ua daim hlau. Nws yog hu ua foil. Tebchaws Europe thiab Tebchaws Meskas feem ntau siv 3 ~ 6 qhov txuas txuas txuas ntxiv ua cov khoom siv txias dov hauv cov txheej txheem tsim khoom. Txij li thaum tsis muaj cua sov thaum lub sijhawm tsim khoom, tsis muaj qhov tsis xws luag xws li pitting thiab hlau oxide nplai uas feem ntau tshwm sim hauv kub dov, thiab qhov zoo ntawm qhov chaw yog qhov zoo thiab qhov ua tiav yog siab. . Tsis tas li ntawd, qhov tseeb qhov tseeb ntawm cov khoom txias-kuav los tiag yog siab, thiab kev ua haujlwm thiab cov qauv ntawm cov khoom tuaj yeem ua tau raws li qee qhov tshwj xeeb rau kev siv, xws li cov khoom siv hluav taws xob thiab cov khoom sib sib zog nqus.

Kev ua tau zoo: Cov qib qis carbon steel feem ntau yog siv, uas yuav tsum tau ua kom txias txias thiab vuam kev ua tau zoo, nrog rau qee yam kev ua haujlwm stamping.
Daim ntawv thov teb: Cold-rolled strips yog dav siv, xws li tsheb tsim, khoom siv hluav taws xob, dov Tshuag, aviation, precision instruments, cov kaus poom zaub mov, thiab lwm yam.
Cold-rolled nyias steel phaj yog cov ntawv luv ntawm cov qauv carbon zoo tib yam steel txias dov phaj, tseem hu ua txias dov phaj, feem ntau hu ua txias-dov phaj, qee zaum ua yuam kev sau ua txias dov phaj. Lub phaj txias yog ib qho kub-kuav los tiag strip ntawm cov pa roj carbon zoo tib yam steel, uas yog ntxiv txias-dov mus rau hauv ib lub phaj steel nrog lub thickness tsawg dua 4 hli. Vim yog dov ntawm chav tsev kub, tsis muaj hlau oxide nplai raug tsim. Yog li ntawd, lub phaj txias muaj qhov zoo ntawm qhov zoo thiab qhov tseeb qhov tseeb. Ua ke nrog kev kho annealing, nws cov khoom siv kho tshuab thiab cov txheej txheem ua haujlwm zoo dua rau cov hlau nplaum kub-dov nyias. Nyob rau hauv ntau lub teb, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm cov khoom siv hauv tsev, nws tau maj mam hloov cov ntawv kub dov steel.
