Kodi annealing kwa defrost heat chubu ndi chiyani?

I. Chidziwitso cha njira yowotchera:

Annealing ndi zitsulo kutentha mankhwala ndondomeko, kutanthauza zitsulo pang`onopang`ono usavutike mtima kwa kutentha zina, anakhalabe kwa nthawi yokwanira, ndiyeno utakhazikika pa liwiro oyenera, nthawi zina zachilengedwe kuzirala, nthawi zina ankalamulira liwiro kuzirala kutentha njira mankhwala.

2. Cholinga cha annealing:

1. Kuchepetsa kuuma, kufewetsa workpiece, kusintha machinability.

2. Kupititsa patsogolo kapena kuthetsa zolakwika zosiyanasiyana za bungwe ndi zovuta zotsalira zomwe zimayambitsidwa ndi chitsulo ndi zitsulo popanga, kupangira, kupukuta ndi kuwotcherera, ndi kuchepetsa kusinthika kwa workpiece, chizolowezi chophwanyidwa kapena chophwanyika.

3. Yenga mbewu, kukonza bungwe kukonza makina katundu workpiece, kuchotsa zofooka za bungwe.

4. Mapangidwe azinthu yunifolomu ndi kapangidwe kake, sinthani zinthu zakuthupi kapena konzani bungwe kuti lizitha kutenthetsa pambuyo pake, monga kutenthetsa ndi kutentha.

3. Choyatsira chotenthetsera chotenthetsera

Makasitomala ambiri amatumiza chubu chowotchera chowongoka chowotcha ndi machubu ena owongoka kuchokera kufakitale yathu, ndiye amatha kupindika mawonekedwe aliwonse okha kuti akwaniritse zofunikira zamakasitomala am'deralo.

Popanga zenizeni, njira yowotchera imagwiritsidwa ntchito kwambiri, malinga ndi zofunikira za workpiece za cholinga cha annealing, chithandizo cha kutentha kwa annealing chimakhala ndi njira zosiyanasiyana, zomwe zimagwiritsidwa ntchito popanga annealing, spheroidizing annealing, kuchepetsa nkhawa ndi zina zotero.
