Cold adagulung'undisa chitsulo ndi zitsulo opangidwa ndi ozizira kugudubuza.Cold rolling ndi pepala lachitsulo lomwe limapezeka mwa kuchepetsanso chitsulo chachitsulo cha nambala 1 kuti chikhale chandamale pansi pa kutentha kwa chipinda.Poyerekeza ndi zitsulo zotentha zotentha, zitsulo zozizira zimakhala ndi makulidwe enieni, osalala komanso okongola, komanso zimakhala ndi makina apamwamba kwambiri, makamaka ponena za processability.Chifukwa makola aiwisi ozizirirapo amakhala olimba komanso olimba, siwoyenera kukonzedwa, ndipo zitsulo zozizira zoziziritsa kukhosi nthawi zambiri zimafunika kuzimitsidwa, kuzifutsa ndi kusalaza pamwamba musanaperekedwe kwa makasitomala.The makulidwe pazipita ozizira akugudubuzika ndi pansi 0.1-8.0MM.Mwachitsanzo, makulidwe a zitsulo zozizira zozizira m'mafakitale ambiri ndi pansi pa 4.5MM;makulidwe osachepera ndi m'lifupi zimatsimikiziridwa molingana ndi mphamvu ya zida ndi kufunika kwa msika wa fakitale iliyonse.
Kusiyanitsa pakati pa zitsulo zozizira ndi zitsulo zotentha sizomwe zimasungunuka, koma kutentha kwa kutentha, kapena kutentha kwa mapeto a kugudubuza.Cold adagulung'undisa zitsulo zikutanthauza kuti kumaliza kutentha ndi otsika kuposa recrystallization kutentha kwa chitsulo.Chitsulo chotentha chimakhala chosavuta kugudubuza ndipo chimakhala ndi mphamvu zambiri zogubuduza, koma pansi pa kutentha, chitsulocho chimakhala ndi oxidized ndipo pamwamba pa mankhwalawa ndi imvi yakuda.Chitsulo chozizira chimafuna mphamvu yayikulu yogudubuza mphero komanso kuyendetsa bwino kwambiri.Annealing wapakatikati amafunikira kuti athetse kuuma kwa ntchito panthawi yogubuduza, motero mtengo wake ndi wokwera.Komabe, chitsulo chozizira chimakhala ndi malo owala komanso abwino, ndipo chingagwiritsidwe ntchito mwachindunji pokonza.zinthu zomalizidwa, kotero kuti mapepala ozizira akugudubuza amagwiritsidwa ntchito kwambiri.
Chophimba chachitsulo chotentha chimagwiritsidwa ntchito ngati zopangira, pambuyo pa pickling kuchotsa sikelo ya oxide, kuzizira kosalekeza kukuchitika, ndipo koyilo yolimba imakulungidwa.Kuzizira kowumitsidwa kochititsidwa ndi kuzizira kosalekeza kumawonjezera mphamvu, kuuma, kulimba ndi indexity ya pulasitiki yamakhola opindika., kotero ntchito yosindikizira idzakhala yosauka, ndipo ingagwiritsidwe ntchito pazigawo zokhala ndi mapindikidwe osavuta.Zozungulira zolimba zolimba zitha kugwiritsidwa ntchito ngati zopangira muzomera zothirira diyi chifukwa mizere yotentha ya dip imakhala ndi mizere yolumikizira.Kulemera kwa koyilo yolimba yokulungidwa nthawi zambiri kumakhala matani 6 ~ 13.5, ndipo koyilo yofutukuka yotenthedwa imakulungidwa mosalekeza kutentha kwa firiji.M'mimba mwake ndi 610mm.
