Kutentha kotenthandi kupanga zitsulo pamwamba pa kutentha kwa recrystallization.
Kuwonjezeka kwa kutentha kumatha kupititsa patsogolo pulasitiki yachitsulo, kumathandizira kupititsa patsogolo khalidwe lamkati la workpiece, kotero kuti sizovuta kusweka. Kutentha kwakukulu kungathenso kuchepetsa kukana kwazitsulo, kuchepetsa matani ofunikira a makina opangira. Koma njira yowotchera yotentha, kulondola kwa workpiece ndikosavuta, pamwamba sikosalala, kupanga kosavuta kutulutsa makutidwe ndi okosijeni, decarburization ndi kutayika koyaka. Pamene workpiece ndi yaikulu ndi wandiweyani, mphamvu zakuthupi ndi mkulu ndi pulasitiki ndi otsika (monga kugubuduza mbale wokhuthala owonjezera, kujambula kutalika kwa mkulu carbon zitsulo ndodo, etc.),kutentha kwachanguamagwiritsidwa ntchito. Pamene chitsulo (monga kutsogolera, malata, nthaka, mkuwa, aluminiyamu, etc.) ali ndi pulasitiki zokwanira ndipo kuchuluka kwa mapindikidwe si lalikulu (monga ambiri masitampu processing), kapena kuchuluka kwa mapindikidwe ndi njira forging ntchito ( monga extrusion, radial forging, etc.) imathandizira kupindika kwa pulasitiki yachitsulo, nthawi zambiri musagwiritse ntchito kufota kotentha, koma gwiritsani ntchito kuzizira kozizira. Kutentha kumasiyanasiyana pakati pa kutentha koyambira ndi kutenthakukonza komalizakutentha kwa forging yotentha kuyenera kukhala kwakukulu momwe kungathekere kuti mukwaniritse ntchito yomanga mochuluka momwe mungathere ndi kutentha kumodzi. Komabe, mkulukukonzekera koyambakutentha kudzachititsa kukula kwambiri zitsulo njere ndi mapangidwe kutenthedwa, amene kuchepetsa khalidwe forging mbali. Kutentha kukakhala pafupi ndi malo osungunuka achitsulo, zinthu zotsika zosungunuka zimasungunuka ndi intergranular oxidation zidzachitika, zomwe zimapangitsa kuwotcha kwambiri. Ma billets otenthedwa kwambiri nthawi zambiri amathyoledwa pakupanga. Generalkutentha kwachangukutentha ndi: mpweya zitsulo 800 ~ 1250 ℃; Aloyi structural zitsulo 850 ~ 1150 ℃; Liwiro zitsulo 900 ~ 1100 ℃; Ambiri ntchito zotayidwa aloyi 380 ~ 500 ℃; Titaniyamu aloyi 850 ~ 1000 ℃; Mkuwa 700 ~ 900 ℃.

Kuzizira kozizirandi m'munsi kuposa zitsulo recrystallization kutentha kwa forging, nthawi zambiri amatchedwa ozizira forging pa firiji, ndipo adzakhala apamwamba kuposa firiji, koma osati kuposa recrystallization kutentha kwa forging amatchedwa ofunda forging. Kulondola kwa kupangira kofunda ndikokwera, pamwamba kumakhala kosalala komanso kukana kwa ma deformation sikuli kwakukulu.
The workpiece opangidwa ndi ozizira forging pansi pa kutentha wabwinobwino ali mkulu mwatsatanetsatane mawonekedwe ndi kukula, yosalala pamwamba, ndondomeko zochepa processing ndi zosavuta automate kupanga. Magawo ambiri ozizira komanso ozizira amatha kugwiritsidwa ntchito mwachindunji ngati magawo kapena zinthu popanda kufunikira kodula. Koma mukuzizira kozizira, chifukwa cha pulasitiki yotsika ya zitsulo, zimakhala zosavuta kusweka panthawi yowonongeka, ndipo kukana kwa deformation ndi kwakukulu, koterokufota kwa matani akulundi makina osindikizira amafunikira.
