M`pofunika kuchita kutentha mankhwala pambuyokupangachifukwa cholinga chake ndikuchotsa kupsinjika kwamkati pambuyo popanga. Sinthani kuuma kolimba, kuwongolera magwiridwe antchito; The coarse njere mu forging ndondomeko ndi woyengedwa ndi yunifolomu kukonzekera microstructure wa zigawo kutentha kutentha.

1. Kutentha kwakukulu kwa kutentha: kuchepetsa kuuma, kuchepetsa kapena kuthetsa kupsinjika komwe kumabwera mukamazizira bwino, kupititsa patsogolo pulasitiki ndi kulimba. Oyenera aloyi zitsulo ndi mkulu kuuma pambuyo normalizing.

2. Kuphatikizika kwathunthu: chotsani mawonekedwe owoneka bwino komanso osagwirizana omwe amachititsidwa ndi kufota, yeretsani njere, chotsani kupsinjika kotsalira kwa kufota, kuchepetsa kuuma, kukonza machinability, ndikukonzekera bungwe kuti lizichitira mtsogolo kutentha kwa magawo. Annealing yathunthu nthawi zambiri imakhala yoyenera chitsulo cha hypoeutectoid.

3. Isothermal annealing: pezani mawonekedwe ofananirako kuposa kutsekereza kwathunthu, kuthetsa kupsinjika kwamphamvu, kuchepetsa kuuma. Pazinthu zazikulu zazikulu, zitha kugwiritsidwanso ntchito kufalitsa haidrojeni ndikuletsa kupanga mawanga oyera. Poyerekeza ndi annealing wathunthu, akhoza kufupikitsa nthawi annealing ndi kusintha bwino kupanga.

4. Normalizing: pearlite yabwino ingapezeke kuti iyeretse bungwe; Sinthanizojambulamphamvu ndi kulimba, kuchepetsa nkhawa mkati, kusintha ntchito yodula; Kwa chitsulo cha eutectoid. Mesh carbides imatha kuthetsedwa.

5 spheroidization annealing: kupeza ozungulira cementite ndi ferrite dongosolo, osati kuchepetsa kuuma, ndi kudula ndondomeko n'zosavuta kuti yosalala processing pamwamba, mu quenching wotsatira si kophweka kubala mapindikidwe ming'alu. Spheroidizing annealing ndi yoyenera chitsulo cha carbon high ndi high carbon alloy die steel.
