Pamwamba pa mbale yoziziritsa ozizira imakhala ndi kuwala kwina ndipo imamveka bwino, mofanana ndi kapu yachitsulo yomwe imagwiritsidwa ntchito popangira madzi akumwa.2. Ngati mbale yotentha yotenthayo siidulidwa, imakhala yofanana ndi pamwamba pa mbale zambiri zachitsulo pamsika.Pamwamba pa dzimbiri ndi ofiira, ndipo pamwamba popanda dzimbiri ndi wofiirira-wakuda (chitsulo okusayidi).

Ubwino wa kagwiridwe ka pepala kozizira kozizira ndi pepala lopindika lotentha ndi:

(1) apamwamba olondola, makulidwe kusiyana ozizira adagulung'undisa Mzere si kuposa 0.01 ~ 0.03mm.

(2) Woonda kukula, thinnest ozizira Kugudubuza akhoza yokulungira 0.001mm zitsulo Mzere;Kugudubuzika kotentha tsopano kumafika pa makulidwe osachepera 0.78mm.

(3) wapamwamba pamwamba khalidwe, ozizira adagulung'undisa zitsulo mbale akhoza ngakhale kutulutsa galasi pamwamba;Pamwamba pa mbale yotentha imakhala ndi zolakwika monga iron oxide ndi pitting.

(4) Pepala lozizira lozizira likhoza kusinthidwa malinga ndi zofunikira za wogwiritsa ntchito zomwe zimayendetsa monga mphamvu zowonongeka ndi machitidwe opangira zinthu monga kupondaponda.

Kuzizira kozizira ndi kugudubuza kotentha ndi njira ziwiri zosiyana zopangira zitsulo, monga momwe dzinalo limatanthawuzira, kuzizira kozizira kumangiriza zitsulo kutentha, kuuma kwachitsulo ichi ndi kwakukulu.Kugudubuza kotentha ndi pamene zitsulo zimangiriridwa pamodzi pa kutentha kwakukulu.Hot adagulung'undisa pepala ali otsika kuuma, processing zosavuta ndi ductility wabwino.Ozizira adagulung'undisa pepala kuuma ndi mkulu, processing ndi zovuta, koma zovuta mapindikidwe, mkulu mphamvu.Mphamvu yopindika yotentha imakhala yotsika, yapamwamba kwambiri pafupifupi (makutidwe ndi okosijeni, otsika), koma mapulasitiki abwino, mbale zambiri zapakatikati, mbale zoziziritsa kuzizira: kulimba kwakukulu, kuuma kwakukulu, kutsirizika kwapamwamba kwambiri, mbale yopyapyala, imatha kugwiritsidwa ntchito ngati kupondaponda mbale.Hot adagulung'undisa zitsulo mbale, makina katundu ndi otsika kwambiri kuzizira processing, komanso otsika pokonza kukonza, koma ali kulimba bwino ndi ductility.Ozizira adagulung'undisa zitsulo mbale chifukwa cha mlingo wina wa ntchito kuumitsa, otsika toughness, koma akhoza kukwaniritsa zabwino flexural chiŵerengero, ntchito ozizira kupinda zidutswa masika ndi mbali zina, pa nthawi yomweyo chifukwa mfundo zokolola ndi pafupi ndi mphamvu yamakokedwe, kotero kugwiritsa ntchito ngozi sikulosera, pamene katunduyo amaposa katundu wololeka amakhala pangozi.Mwa tanthawuzo, ingot yachitsulo kapena billet ndizovuta kusokoneza ndi kukonza kutentha kwa firiji.Nthawi zambiri imatenthedwa mpaka 1100 ~ 1250 ℃ pakugudubuza.Kugudubuzika kumeneku kumatchedwa hot rolling.Zitsulo zambiri zimakulungidwa ndi kugudubuza kotentha.Komabe, chifukwa pamwamba zitsulo n'zosavuta kupanga okusayidi pepala pa kutentha kwambiri, pamwamba pa otentha adagulung'undisa zitsulo ndi akhakula ndi kukula zimasinthasintha kwambiri, kotero chitsulo ndi yosalala pamwamba, kukula zolondola ndi katundu wabwino makina chofunika, ndi otentha. Zopiringa zomalizidwa kapena zomalizidwa zimagwiritsidwa ntchito ngati zopangira kenako zimapangidwa ndi njira yozizira.Kugudubuza kutentha kwa chipinda nthawi zambiri kumamveka ngati kugudubuza kozizira.Kuchokera kumalingaliro a sayansi yachitsulo, malire pakati pa kuzizira kozizira ndi kugudubuza kotentha ayenera kusiyanitsidwa ndi kutentha kwa recrystallization.Ndiko kuti, kugubuduza m'munsimu kutentha recrystallization ozizira anagubuduza, ndi anagubuduza pamwamba pa recrystallization kutentha ndi otentha anagubuduza.The recrystallization kutentha zitsulo ndi 450 ~ 600 ℃.Hot anagubuduza, monga dzina limatanthawuzira, anagubuduza mbali za kutentha, kotero mapindikidwe kukana ndi yaing'ono, akhoza kukwaniritsa mapindikidwe lalikulu.Kutenga chitsulo mbale akugubuduza mwachitsanzo, makulidwe a mosalekeza kuponyera billet ndi za 230mm, ndipo pambuyo akugubuduza akhakula ndi kutsiriza kugudubuza, makulidwe omaliza ndi 1 ~ 20mm.Pa nthawi yomweyo, chifukwa makulidwe chiŵerengero cha mbale zitsulo ndi yaing'ono, kulondola dimensional ndi otsika, si zophweka kuonekera vuto mawonekedwe, makamaka kulamulira korona.The microstructure ndi katundu makina a Mzere zitsulo akhoza kulamulidwa ndi kulamulira anagubuduza kutentha, anagubuduza kutentha ndi crimping kutentha.Kuzizira kozizira, nthawi zambiri kulibe njira yotenthetsera musanagubuduze.Komabe, chifukwa makulidwe ake ndi ochepa, ndizosavuta kuwoneka vuto la mawonekedwe.Kuphatikiza apo, kugudubuza kozizira kumalizidwa, chifukwa chake, kuti muwongolere kulondola kwatsatanetsatane komanso mtundu wamtundu wazitsulo, njira zambiri zotopetsa zimagwiritsidwa ntchito.Cold anagubuduza kupanga mzere yaitali, zida zambiri, ndondomeko zovuta.Ndi kusintha kwa owerenga 'mafunika pa mlingo kulondola, mawonekedwe ndi pamwamba khalidwe la zitsulo Mzere, pali zitsanzo zambiri kulamulira, L1 ndi L2 machitidwe ndi njira kulamulira mawonekedwe mu ozizira akugudubuza mphero kuposa otentha anagubuduza mphero.Kuphatikiza apo, kutentha kwa roller ndi strip ndichilombo chofunikira kwambiri chowongolera.Ozizira adagulung'undisa mankhwala ndi otentha adagulung'undisa mankhwala pepala mzere, ndi kusiyana pakati pa ndondomeko yapita ndi ndondomeko yotsatira, mankhwala otentha adagulung'undisa ndi zipangizo ozizira adagulung'undisa mankhwala, ozizira adagulung'undisa pambuyo pickling otentha adagulung'undisa zitsulo koyilo makina ntchito wodzigudubuza mphero, anagubuduza, ndi ozizira processing akamaumba, makamaka akugubuduza wandiweyani otentha adagulung'undisa mbale mu specifications woonda wa mbale ozizira adagulung'undisa, Kawirikawiri monga 3.0mm otentha adagulung'undisa mbale pa makina anagubuduza akhoza kutulutsa 0.3-0.7mm ozizira adagulung'undisa koyilo, mfundo yaikulu ndi kugwiritsa ntchito mfundo extrusion kukakamizidwa kupindika.
