Cold rolled steel yog hlau ua los ntawm txias dov.Txias dov yog ib daim ntawv hlau uas tau txais los ntawm kev txo qis ntawm No.1 steel ntawv mus rau lub hom phiaj tuab nyob rau hauv chav tsev kub.Piv nrog kub-kuav los tiag steel, txias-kuav los tiag steel muaj ib tug ntau leej tuab tuab, ib tug du thiab zoo nkauj nto, thiab kuj muaj ntau yam superior mechanical zog, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm processability.Vim tias cov ntawv txias-kuav los tiag coils yog nkig thiab tawv, lawv tsis haum rau kev ua, thiab cov ntawv txias-kuav los tiag steel feem ntau yuav tsum tau annealed, pickled thiab nto smoothed ua ntej xa mus rau cov neeg muas zaub.Qhov siab tshaj plaws thickness ntawm txias dov yog qis dua 0.1-8.0MM.Piv txwv li, lub thickness ntawm txias-kuav los tiag steel phaj nyob rau hauv feem ntau factories yog qis dua 4.5MM;qhov tsawg kawg nkaus thickness thiab dav yog txiav txim raws li cov cuab yeej muaj peev xwm thiab kev lag luam xav tau ntawm txhua lub Hoobkas.
Qhov sib txawv ntawm txias-dov hlau thiab kub-kuav los tiag hlau tsis yog cov txheej txheem smelting, tab sis dov kub, los yog qhov kawg kub ntawm dov.Txias dov hlau txhais tau hais tias qhov kub ntawm qhov kawg yog qis dua qhov kub ntawm recrystallization ntawm cov hlau.Kub-dov hlau yog ib qho yooj yim rau yob thiab muaj kev ua haujlwm siab dov, tab sis nyob rau hauv qhov kub-dov, cov hlau yog oxidized thiab qhov chaw ntawm cov khoom yog tsaus grey.Cold-dov hlau yuav tsum muaj siab dov zeb lub zog thiab qis dov efficiency.Intermediate annealing yuav tsum tau tshem tawm kev ua hauj lwm hardening thaum lub sij hawm dov txheej txheem, yog li tus nqi kuj yog siab.Txawm li cas los xij, cov hlau txias txias muaj qhov ci ntsa iab thiab zoo, thiab tuaj yeem siv ncaj qha rau kev ua haujlwm.Cov khoom tiav, yog li cov ntawv txias txias steel tau siv dav.
Cov kub dov steel kauj yog siv los ua cov khoom siv raw, tom qab pickling kom tshem tawm cov oxide nplai, qhov txias nruam dov yog nqa tawm, thiab lub zog coil yog dov.Txias ua hauj lwm hardening induced los ntawm tas mus li txias deformation tsub kom lub zog, hardness, toughness thiab plasticity Performance index ntawm dov hard coils., yog li qhov kev ua haujlwm stamping yuav tsis zoo, thiab nws tsuas yog siv tau rau qhov chaw uas yooj yim deformation.Hard dov coils tuaj yeem siv los ua cov khoom siv raw hauv cov nroj tsuag kub dip galvanizing vim kub dip galvanizing kab yog nruab nrog cov kab annealing.Qhov hnyav ntawm dov hard coil feem ntau yog 6 ~ 13.5 tons, thiab cov kub dov pickled coil yog txuas ntxiv dov ntawm chav tsev kub.Sab hauv txoj kab uas hla yog 610mm.
