Cold kugubuduza mu recrystallization kutentha m'munsimu wotchedwa ozizira adagulung'undisa, otentha adagulung'iza koyilo monga zopangira, amagwiritsidwa ntchito mu asidi pickling kuchotsa okusayidi khungu pambuyo ozizira anagubuduza, chomalizidwa ndi zovuta, chifukwa cha kuzizira ntchito kuumitsa chifukwa mapindikidwe mosalekeza. ozizira kugubuduza molimba mpukutu mphamvu, kuwonjezera kuuma, toughness ndi pulasitiki index utachepa, kotero ntchito yopondaponda adzawonongeka, angagwiritsidwe ntchito mapindikidwe yosavuta mbali.
Koyilo yolimba ingagwiritsidwe ntchito ngati zopangira, fakitale yotentha yoviyitsa malata yopangira zida zopangira zokometsera zokometsera ndi waya.
Kulemera kwa voliyumu mu 20 - ambiri
40 matani, zitsulo koyilo, firiji kwa mosalekeza Kugubuduza otentha adagulung'undisa pickling mabuku.
Zida zoziziritsa kuzizira: chifukwa palibe chithandizo chamankhwala pambuyo pa annealing, kuuma kwake kumakhala kwakukulu (
HRB ndi yayikulu kuposa 90)
, makina processing ntchito ndi osauka, ophweka okha ndi directivity ndi zosakwana 90 digiri mapindikidwe processing.

Kuzizira adagulung'undisa ndondomeko processing.
Cold anagubuduza ndi pansi udindo wa kukonzedwa ndi otentha anagubuduza mbale, pamene m'kati machining kwa anagubuduza adzapanga zitsulo mbale kutentha, komabe amatchedwa ozizira anagubuduza.
Chifukwa cha kuzizira kopitilira muyeso kwa kuzizira kopitilira muyeso wamakina kumakhala kocheperako, kulimba ndikwambiri, kotero kuyenera kudutsa mu annealing kuti kubwezeretsedwa kwa makina ake, popanda kutsekereza kumakhala kovuta.
Koyilo yolimba imagwiritsidwa ntchito kwambiri kuchita popanda kupinda, zinthu zotambasula, 1.
Pansi pa makulidwe a ziro mbali zonse za mwayi wabwino kapena kupindika kwa quadrilateral.
Kuziziritsa adagulung'undisa zambiri pambuyo annealing mankhwala.
Ayenera kugwiritsidwa ntchito pozizira kugudubuza ozizira mafuta anagubuduza, ubwino ntchito ozizira anagudubuzika mafuta ndi: 1, bwino kuchepetsa mikangano koyenerika, kupereka lolingana anagubuduza mphamvu, anagubuduza mowa otsika mphamvu, ndi wokhutiritsa anagubuduza magawo;
2, kupanga kuwala pamwamba pamwamba ndi makulidwe yunifolomu akugudubuza kuchedwa;
3, kuzirala kwabwino, kumatha kuchotsa kugudubuza kotentha, kuteteza mpukutu ndi chidutswa.
Kuchita bwino kwa Annealing, sikungabweretse chodabwitsa choyaka mafuta;
4, kukhala ndi ntchito yanthawi yayitali yolimbana ndi dzimbiri, imatha kupereka chitetezo kwakanthawi kwa zidutswa zogubuduzika.

Ndi gawo la ntchito yotentha yopukusa.
Hot adagulung'undisa mkulu kupanga dzuwa, lalikulu, mochepa mphamvu, mtengo wotsika, digiri mkulu wa zimango, zochita zokha, oyenera kupanga misa mu mzere, ndi imodzi mwa zofunika kwambiri zitsulo kuthamanga processing njira.
Hot adagulung'undisa ndi processing zitsulo mapindikidwe kukana ndi otsika ndi pulasitiki ndi chimagwiritsidwa ntchito.
Koma popeza kutentha kwachidutswa sikophweka mofanana pogubuduza, pamwamba pa tini oxide pali, kulondola kwa kukula kwa chinthu ndi kuuma kwa pamwamba ndizinthu zochepa zozizira.
Chida chachikulu chopangira mphero yotentha.
Amagwiritsidwa ntchito mu mphero yotentha ndi ma phyletic ambiri, pali mphero ziwiri, mphero zitatu, mphero zophera, mphero zinayi zapamwamba, Y type rolling mill, two-high skew rolling mphero, atatu-roll skew rolling mphero. , mphero yodutsa, mphero yapadziko lonse ndi mitundu yonse ya mphero yapadera ndi zina zotero.
Malinga ndi zofunikira pakupanga mitundu yosiyanasiyana ya zinthu, mtundu wazinthu, kupanga, malo, ndi zina zambiri, pali mitundu yambiri ya mphero yopukusira yotentha yopangira msonkhano, monga masanjidwe a makina amodzi, mizati imodzi kapena zingapo za sitima yotseguka. dongosolo, dongosolo kutsatira, kugubuduza mtundu masanjidwe, chessboard mtundu chokongoletsedwa, etc.
Njira zopangira zopangira zotentha nthawi zambiri zimaphatikizapo kukonzekera kwa zipangizo, kutentha, kugudubuza, kutsirizitsa ndi zina zotero.
Hot anagubuduza angagwiritsidwe ntchito akugubuduza zitsulo ingot kapena billet lalikulu, kupanga zinthu zazikulu kukula.
Monga ingot yaikulu kugubuduza 70 t mkati ndi mozungulira 50 t billet lalikulu, kupanga makulidwe a 500 mm wandiweyani mbale, osasokonekera zitsulo chitoliro cha 1070 mm awiri, 1200 mm × 530 MMH zitsulo ndi 78 kg/mamita njanji, etc.
M'nyengo yotentha yogudubuza, kutentha kwachidutswa kumachepetsa pang'onopang'ono, kukana kwa zinthu zowonongeka kumawonjezeka pang'onopang'ono, pamapeto pake sikungapange malo otentha.
Choncho si kukula kwa mankhwala otentha adagulung'undisa angakhale ang'onoang'ono, akhoza kukhala 1 mm wandiweyani pepala anagubuduza, 20 mm m'mimba mwake opanda zitsulo chitoliro, awiri a 5.

Hot anagubuduza akhoza kukhala lalikulu kupanga mphamvu, linanena bungwe pachaka 6 miliyoni T wa akhakula mphero, ngati alipo, ndi mphamvu pachaka 6 miliyoni T otentha adagulung'undisa DaiGangChang etc.
Zogulitsa zotentha zimatha kugawidwa ndi mawonekedwe amtundu wamtundu wamtundu wowotcha, chitoliro chotentha chosasunthika, chitoliro chachitsulo chotentha ndi chitsulo chapadera chotentha chopiringitsa makalasi anayi.
Hot adagulung'undisa ndi anagubuduza njira makamaka ogaŵikana longitudinal anagubuduza, skew anagubuduza ndi anagudubuza.
Kusiyanitsa pakati pa ozizira adagulung'undisa ndi otentha adagulung'undisa, ozizira adagulung'undisa mu zigawo 1 kulola m'deralo buckling gawo, amene angagwiritse ntchito mokwanira bala buckling kubala mphamvu pambuyo;
Local buckling ndi otentha adagulung'undisa zitsulo salola mtanda gawo.
2, zomwe zimayambitsa kutentha zitsulo ndi zitsulo zozizira zotsalira zotsalira ndizosiyana, kotero kugawidwa kwa gawo la mtanda kumakhalanso ndi kusiyana kwakukulu.
Chigawo chozizira chokhala ndi mipanda yopyapyala pamagawo otsalira opsinjika ndi chopindika, ndipo chitsulo chotenthetsera kapena chitsulo chosungunula chotsalira chotsalira pagawo la mtanda ndi filimu yopyapyala.
3, chitsulo chowotcha chopanda chitsulo chosasunthika chimakhala chokwera kuposa chitsulo chozizira, chifukwa chake chitsulo chosungunulira chimakhala chabwino kuposa chitsulo chozizira.
