Annealing ndi kutentha kwa kutentha kwa chitsulo chakufa ku Ac3 (hypo-eutectoid steel) kapena Accm (eutectoid ndi hyper-eutectoid steel) pamwamba pa 30 ~ 50 ° C, kupeza austenite, kuziziritsa mumlengalenga, ndi kutentha kwa kutentha kwa yunifolomu ntchito ya pearlite.
Cholinga cha normalizing: ndi normalizing wa kufa zitsulo ndi kusintha machinability, kuthetsa otentha ntchito zolakwika, kuthetsa maukonde carbide mu hypereutectoid kufa zitsulo, kukonzekera spheroidizing annealing dongosolo, ndi kusintha mawotchi zimatha kufa.
Annealing ndi njira yochizira kutentha yomwe chitsulo chakufa chimatenthedwa kutentha pamwamba kapena pansi pa malo ovuta kwambiri Ac1, ndiyeno pang'onopang'ono kuziziritsidwa ndi kutentha kwa ng'anjo pambuyo posungira kutentha kuti mupeze dongosolo lapafupi lofanana.
Cholinga cha annealing: Cholinga chachikulu ndi homogenize kapangidwe ka mankhwala ndi kapangidwe ka chitsulo chakufa, kuyenga mbewu, kusintha kuuma, kuthetsa nkhawa ndi kuuma ntchito, kukonza mapangidwe ndi machinability wa chitsulo, ndi kukonzekera dongosolo kuzimitsa. .
Die steel annealing classification: Mitundu ya die steel annealing imaphatikizapo diffusion annealing, isothermal annealing, incomplete annealing, spheroidizing annealing, recrystallization annealing and stress relief annealing.
