Dab tsi yog txias - rolled chev?
Cold-rolled coil is a steel coil produced by rolling hot-rolled coil at room temperature through a cold rolling mill. Tsis muaj cua sov tau thov thaum lub sij hawm yob, thiab hloov, cov hlau cov tsos thiab cov khoom tau hloov kho los ntawm kev ua siab. Cov khoom lag luam tshwj xeeb cov khaub ncaws tuab zoo nkauj, ib qho chaw du, thiab siab qhov tseeb.

Yuav ua li cas tuaj yeem txias- rolled coil raug cais raws li cov mob?
Raws li cov txheej txheem kev kho mob saum npoo av, txias - rolled chev feem ntau muab faib ua cov hauv qab no:
Mob khaub thuas zoo tib yam - rolled coil (thau cov xim dub (khaws cia ua kom tiav (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua kom tiav (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li pleev xim rau (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li pleev xim rau (xws li pleev xim rau (xws li pleev xim rau cov xim ntxiv (xws li kev ua tiav tom qab (xws li pleev xim rau (xws li pleev xim rau lossis ua cov duab);
Galvanized txias-} {{- dip galvanized / haum rau kev siv zuaj lossis huab cua ib puag ncig;
Color-coated cold-rolled coil: Coated with a colored coating (such as polyester or fluorocarbon coating), aesthetically pleasing and corrosion-resistant, suitable for building exteriors and appliance housings;
Galluzinc Txias - rolled chev: coated zoo tshaj plaws corrosizing, haum rau photovoltaic mounting nkhaus thiab tsheb tso dej.
Dab tsi yog qhov tseem ceeb tshaj plaws ntawm txias - rolled thiab kub {1} {dov kauj?
Qhov ob txawv txawv cuam tshuam nyob rau hauv cov txheej txheem ntau lawm, kev ua tau zoo, thiab thov daim ntawv teev xwm txheej. Cov ncauj lus piav qhia ntxaws yog raws li hauv qab no:
Comparison Dimensions: Cold-rolled Coil Hot-rolled Coil
Kev Kub Kub Tshaj: Chav Tsev (Hauv qab ntawm cov recrystallization kub) kub (saum cov recrystallization kub, feem ntau 1100-1250 degree)
Thickness qhov tseeb: siab (± (± 0.01-0.03 hli kev sib txawv) tsawg (± 0.1-0.3mm ruam)
Nto zoo: du, tsis muaj oxide nplai ntxhib, nrog oxide teev (yuav tsum tau pickling)
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Muaj lub zog siab, kev xav tau qis dua (xav tau annealing rau kev txhim kho) lub zog qis, siab ductility
Cov Ntawv Thov: Khoom siv precision (cov khoom siv hauv tsev, cov khoom siv tsheb lag luam) cov qauv txheej txheem (pipelines, cov qauv steel)
Dab tsi yog "annealing" txheej txheem rau txias - rolled coil? Nws lub hom phiaj yog dab tsi?
Annealing yog qhov tseem ceeb ntawm kev kho cua txias tom qab lub zog txias: lub txias} Cov haujlwm suav nrog:
Txo cov "ua haujlwm hnyav" (sab hauv kev ntxhov siab) tshwm sim los ntawm cov khaub noom txias, rov kho cov yas yas rau cov stamping txuas ntxiv thiab khoov;
Refining cov mov loj, homogenizing tus qauv, thiab txhim kho cov hlau cov khoom siv (xws li ua lub zog thiab elongation);
Txhim kho cov nto zoo, tiv thaiv kev tawg thiab deformation thaum ua tiav.
