The annealing process ofzojambulachitha kugawidwa mu annealing wathunthu, annealing osakwanira, spheroidizing annealing, diffusion annealing (homogenizing annealing), isothermal annealing, de-stress annealing ndi recrystallization annealing malinga ndi kapangidwe, zofunika ndi cholinga cha annealing.
(1) ndondomeko yomaliza ya annealing
①Chigawo cha ntchito:Sing'anga mpweya zitsulo, sing'anga mpweya mkulu aloyi zitsulo castings, sing'anga mpweya otsika aloyi zitsulo castings, mbali kuwotcherera,zojambula, anagulung'undisa mbali ndi mankhwala ena annealing.
② Wophatikizidwa kwathunthu ndi B
A. Konzani kamangidwe kambewu, yeretsani kukula kwambewu, chotsani mawonekedwe a Widmannian ndi ma bande;
B. Kuchepetsa kuuma ndi kukonza ntchito yodula;
C. Kuchotsa kupsinjika kwamkati;
D. Chithandizo chomaliza cha kutentha kwa zigawo zosafunikira.
(2) Kusakwanira kwa annealing
①Chigawo cha ntchito:Annealing mankhwala a hypoeutectoid zitsulo, carbon structural chitsulo, carbon chingwe chida zitsulo, otsika aloyi structural chitsulo, otsika aloyi chida zitsulo ndi hyeutectoid zitsulo forgings, otentha adagulung'undisa mbali, etc.
②Cholinga chosakwanira annealing:kuthetsa kupsinjika kwamkati kwa kugubuduza, kuchepetsa kuuma komanso kukonza kulimba.
(3) spheroidizing annealing
①Chigawo cha ntchito:
A. Kukonzekera ndi kutentha kutentha kwa kubala ndi zida zitsulo ndi zitsulo zina hypereutectoid;
B. Cold deformation forging annealing treatment of the medium and low carbon steels and medium and low carbon alloy steels.
②Cholinga cha spheroidizing annealing:
A. Chifukwazojambulazomwe ziyenera kudulidwa, kuchepetsa kuuma ndi kupititsa patsogolo ntchito yodula;
B. Kupititsa patsogolo plasticity ya workpiece ozizira-opunduka popanda kudula;
C. Carbide yozungulira kuti ateteze kutenthedwa kwa kuzimitsa kotsatira ndi kukonzekera kuikidwa m'manda kotentha;
D. Chotsani kupsinjika kwamkati.
(4) Kuwotcha kwa Isothermal
①Kugwiritsa ntchito annealing ya isothermal:kufa zitsulo, aloyi zitsulo forgings, stamping mbali.
②Ubwino wa annealing isothermal:imatha kufupikitsa kuzungulira kwa annealing ndikuchepetsa mtengo wopanga.
