Zomwe zimagwiritsidwa ntchito ndi zitsulo zomwe zimagwiritsidwa ntchito ndizosakhazikika chifukwa cha kuchuluka kwa zonyansa zomwe zimagwiritsidwa ntchito pamigodi.Njira yochizira kutentha imatha kuwayeretsa bwino ndikuwongolera chiyero chawo chamkati, ndipo ukadaulo wamankhwala otenthetsera ukhoza kulimbikitsanso kuwongolera kwawo ndikuwongolera magwiridwe antchito awo enieni.Kutentha mankhwala ndi ndondomeko imene workpiece ndi mkangano ena sing'anga, usavutike mtima kwa kutentha kwina, kusungidwa pa kutentha kwa nthawi inayake, ndiyeno utakhazikika pa mitengo yosiyana.
Monga imodzi mwazinthu zofunika kwambiri pakupangira zida, ukadaulo wamankhwala achitsulo ali ndi zabwino zambiri poyerekeza ndi njira zina zopangira zida."Moto unayi" mu chithandizo cha kutentha kwachitsulo umatanthawuza kutsekemera, kukhazikika, kuzimitsa (kuthetsa) ndi kutentha (kukalamba).Pamene workpiece ndi kutenthedwa ndi kufika kutentha kwina, ndi annealed ntchito zosiyanasiyana akugwira malinga ndi kukula kwa workpiece ndi zinthu, ndiyeno pang'onopang'ono utakhazikika.Cholinga chachikulu cha annealing ndi kuchepetsa kuuma kwa zinthu, kukonza pulasitiki ya zinthuzo, kuthandizira kukonzanso kotsatira, kuchepetsa kupanikizika kotsalira, ndikugawa mofanana momwe zinthuzo zimakhalira komanso momwe zimakhalira.
Machining ndikugwiritsa ntchito zida zamakina ndi zida zopangira magawo opangira,kukonza magawoisanayambe ndi itatha processing adzakhala lolingana kutentha mankhwala ndondomeko.Udindo wake ndi ku.
1. Kuchotsa kupsyinjika kwamkati kwa chopanda kanthu.Nthawi zambiri amagwiritsidwa ntchito ngati castings, forgings, welded mbali.
2. Kupititsa patsogolo zinthu zowonongeka, kuti zinthuzo zikhale zosavuta kukonza.Monga annealing, normalizing, etc.
3. Kupititsa patsogolo makina onse azinthu zazitsulo.Monga tempering mankhwala.
4. Kupititsa patsogolo kuuma kwa zinthu.Monga kuzimitsa, kuzimitsa carburizing, etc.
Choncho, kuwonjezera pa kusankha koyenera kwa zipangizo ndi njira zosiyanasiyana zopangira, njira yopangira kutentha nthawi zambiri imakhala yofunikira.
Kutentha kwamankhwala nthawi zambiri sikumasintha mawonekedwe ndi kapangidwe kake kake ka workpiece, koma posintha mawonekedwe a microstructure mkati mwa workpiece, kapena kusintha kapangidwe kake kapamwamba ka workpiece, kupereka kapena kukonza magwiridwe antchito a workpiece.Zimadziwika ndi kuwongolera kwamkati kwa kachipangizo kantchito, komwe nthawi zambiri sikumawoneka ndi maso.
