168 Forgings net: lits'ebetso tsa annealing tsa forgings ke life?

Forgings of annealing process ho ea ka litlhoko tsa sebopeho sa morero o fapaneng oa ho koala, o ka aroloa ka botlalo annealing annealing annealing spheroidizing annealing (homogenizing annealing) ho hatella annealing le isothermal annealing recrystallization annealing scope of application:

(1) ts'ebetso e felletseng ea annealing ea carbon steel carbon high alloy steel castings ea carbon in low alloy iron castings weldments forgings rolling parts tse kang annealing annealing ka ho feletseng.

a.B ho ntlafatsa sebopeho sa lijo-thollo tse teteaneng, ho hloekisa lijo-thollo, ho felisa sebopeho sa widmanstatten le sebopeho sa lihlopha;

B. Fokotsa boima le ho ntlafatsa ts'ebetso ea ho itšeha;

C. Felisa khatello ea kelello ka hare;

D. E ka sebelisoa e le phekolo ea ho qetela ea mocheso bakeng sa likarolo tse sa hlokahaleng.

(2) Ts'ebetso e sa phethahalang ea ho phunya

Sekhahla sa kopo: tšepe ea subeutectoid, tšepe ea sebopeho sa carbon, tšepe ea tšepe ea thapo, tšepe e tlase ea alloy, tšepe e tlase ea alloy le tšepe ea hypereutectoid, likotoana tse chesang joalo-joalo.
Sepheo se sa phethoang sa annealing: ho felisa khatello ea kelello ea ka hare ea ho forging le rolling, ho fokotsa boima, ho ntlafatsa ho tiea.

(3) Spheroidizing annealing
Sebaka sa ts'ebeliso:
A. Ho itokisa mocheso oa phekolo ea tšepe ea hypereutectoid joalo ka tšepe e nang le tšepe le tšepe ea sesebelisoa;
B. Cold deformed forging annealing treatment of medium and low carbon steels le medium and low carbon alloy steels.
Sepheo sa spheroidizing annealing
A. Bakeng sa forgings hloka ho itšeha, fokotsa ho thatafala le ho ntlafatsa ho itšeha tshebetso;
B. Bakeng sa batang deformation workpiece ntle ho itšeha, ntlafatsa polasetiki ea batang deformation workpiece;
C. Spheroidized carbide ho thibela mocheso o feteletseng ka mor'a ho tima le ho itokisetsa ho patoa sebakeng sa ho qetela se chesang;
[D] Felisa khatello ea kelello ka hare.

(4) Ho kenngoa ha Isothermal
Sesebelisoa sa Isothermal annealing: tšepe ea die, tšepe ea alloy forging, likarolo tsa setempe.
Melemo ea annealing ea isothermal: e ka khutsufatsa potoloho ea annealing, ea fokotsa litšenyehelo tsa tlhahiso.
