Ke mekhoa efe e tloaelehileng ea annealing ea mochini o holisang maqhubu a phahameng

1. Anealing e sa fellang: Ho phunya ho sa fellang ke mokhoa oa ho phunya moo tšepe ea carbon alloy e futhumatsang mocheso o mahareng oa Ac1-Ac3 ho fihlela martensitis e sa fellang, e lateloang ke ho pholisa butle. Annealing e sa fellang e loketse haholo-holo bakeng sa tšepe e bohareng, e bohareng ea k’habone le litšepe tse phahameng tsa alloy, joalo-joalo;

2. Spheroidizing annealing: ho futhumatsa tšepe mochesong o ka tlase hanyane kapa o phahameng ho feta Ac1 kapa ho fetola mocheso ho potoloha A1 ka nako e itseng, ebe o pholile butle. Spheroidizing annealing e sebelisetsoa ho fokotsa boima bo phahameng ba tšepe ea alloy le No. 45 tšepe ka mor’a ho lahla;

3. Isothermal annealing: e sebelisetsoang ho fokotsa boima bo phahameng ba lisebelisoa tse ling tsa alloy tse nang le likarolo tse phahameng tsa nickel le chromium ho etsa tlhahiso ea ho cheka le ho sebetsa;

4. Annealing ka ho feletseng: mochine o tiileng oa mocheso o feteletseng o nang le thepa e fokolang ea ‘mele ka mor’a ho forging, casting le welding ea motlakase ea carbon steel e phahameng;

5. Ho imolla khatello ea kelello fatše: e sebelisetsoang ho tlosa khatello ea mocheso ea li-castings tsa tšepe le li-welds;

6. External diffusion annealing: e sebelisetsoa ho homogenize sebopeho sa aluminium alloy castings le ho ntlafatsa matšoao a bona a ts’ebetso;

7. Ho sebetsa ho thatafatsa annealing: E ​​sebelisoa ho tlosa boemo bo thata ba lithapo tsa tšepe le lishiti tsa tšepe nakong eohle ea ho taka le serame se batang, le ho tlosa phello e batang ea ho thatafatsa ho nolofatsa lisebelisoa tsa tšepe.

1. Graphitization annealing: Mochini o hanelang oa maqhubu a holimo o sebelisoa ho fetola tšepe ea kolobe e nang le samente e ngata hore e be tšepe e entsoeng ka tšepe e ka tšeptjoang e nang le deformation e ntle ea polasetiki. Ka mor’a ho futhumatsa mocheso o itseng, ho thibela mocheso ka nako e itseng ebe ho pholile ho itekanetseng, e le hore cementite e qhibilihe ho hlahisa graphite e phahameng ea flocculent.
