Cold dov steel yeeb nkab yog tsim los ntawm cov txheej txheem txias-kuav los tiag.Txias-dov yog nyob rau hauv chav tsev kub rau ib tug ntxiv dov mus rau lub hom phiaj thickness ntawm nyias phaj.Thiab kev sib piv ntawm cov hlau kub-kuav los tiag, txias dov steel phaj thickness yog qhov tseeb dua, thiab qhov saum npoo yog du, zoo nkauj, tab sis kuj muaj ntau yam khoom siv zoo heev, tshwj xeeb tshaj yog kev ua haujlwm.Vim tias cov coil coil coil yog tsis tsim nyog rau kev ua, yog li nyob rau hauv ib txwm muaj xwm txheej yuav tsum tau txias-kuav los tiag steel ntawv tom qab annealing, pickling thiab nto roughness raug xa mus rau tus neeg muas zaub.Qhov siab tshaj plaws thickness yog 0.1-8.0MM tsawg dua txias-dov, txias-kuav los tiag steel ntawv thickness raws li feem ntau ntawm cov factories yog 4.5MM tsawg dua;yam tsawg kawg nkaus thickness, dav raws li cov cuab yeej muaj peev xwm thiab kev lag luam xav tau yog txiav txim siab rau txhua tsob nroj.

Txias dov steel thiab kub-dov hlau smelting txheej txheem tsis paub qhov txawv, tab sis dov kub, los yog dov kawg kub.Qhov kawg dov kub yog qis dua qhov ntsuas kub ntawm recrystallization ntawm cov khoom siv hlau ua cov hlau txias-dov.Yooj yim dov kub dov hlau, siab dov efficiency, tab sis oxidation ntawm steel kub dov mob, cov khoom nto yog tsaus grey bleak.Cold-dov steel zeb zog yuav tsum tau, tsis tshua muaj dov efficiency, thiab dov txheej txheem nyob rau hauv thiaj li yuav tshem tawm kev ua hauj lwm-hardening tab sis kuj rau intermediate annealing, yog li tus nqi siab dua, tab sis lub txias-dov steel ci nto, zoo zoo, tuaj yeem siv ncaj qha. rau kev ua tiav cov khoom, tshwj xeeb tshaj yog txias-kuav los tiag steel yog dav qhia.

Kub dov steel kauj raws li cov khoom siv raw, tom qab txias dov pickling descaling, cov khoom tiav yog dov cov ntim nyuaj, vim kev ua haujlwm tsis tu ncua los ntawm txias deformation dov nyuaj ntim ntawm lub zog, hardness nce tawv tawv index poob.Yog li stamping kev ua tau zoo yuav deteriorate, tsuas yog rau yooj yim deformation ntawm qhov chaw.Rolling nyuaj ntim yuav siv tau raws li raw khoom rau kub dip galvanizing cog, vim kub dip galvanizing kab yog muab nrog annealing kab.Rolling hard volume nyhav feem ntau yog los ntawm 6 mus rau 13.5 tons, steel coils ntawm chav tsev kub, kub dov pickled coils rau nruam dov.Ib txoj kab uas hla ntawm 610mm.
