Mekhoa ea ho theha tšepe ea alloy e susumetsa haholo ho thatafala ha sehlahisoa sa ho qetela, ntlha ea bohlokoa ho khethollang ts'ebetso le ho tšoarella ha karolo. Litšepe tsa alloy, tse entsoeng ka tšepe le lintho tse ling tse kang chromium, molybdenum, kapa nickel, li bonts'a lisebelisoa tse ntlafalitsoeng tsa mochini ha li bapisoa le litšepe tsa k'habone. Mokhoa oa ho theha, o kenyelletsang ho senyeha ha tšepe o sebelisa matla a khatello, o bapala karolo ea bohlokoa ho lokiseng thepa ena, haholo-holo ho thatafala.
Mekhoa ea ho Forging le phello ea eona ho boima
1. Hot Forging: Ts'ebetso ena e kenyelletsa ho futhumatsa tšepe ea alloy ho mocheso ka holimo ho ntlha ea eona ea recrystallization, hangata pakeng tsa 1,100 ° C le 1,200 ° C. Mocheso o phahameng o fokotsa viscosity ea tšepe, e leng se lumellang hore ho be bonolo ho fetoha. Mocheso oa forging o khothalletsa sebopeho sa lijo-thollo tse hloekisitsoeng, ho matlafatsa thepa ea mochine oa tšepe, ho kenyelletsa le ho thatafala. Leha ho le joalo, ho thatafala ha ho qetela ho itšetlehile ka sekhahla se latelang sa ho pholisa le phekolo ea mocheso e sebelisoang. Ho pholisa ka potlako ho ka lebisa ho boima bo eketsehileng ka lebaka la ho thehoa ha martensite, ha ho pholile butle ho ka etsa hore ho be le lintho tse halefileng, tse thata haholo.
2. Cold Forging: Ho fapana le ho qhekella ho chesang, ho qhekella ho batang ho etsoa ka mocheso oa kamore kapa haufi le oona. Ts'ebetso ena e eketsa matla le ho tiea ha thepa ka ho thatafatsa kapa ho thatafatsa mosebetsi. Cold forging e molemo bakeng sa ho hlahisa litekanyo tse nepahetseng le sephetho se phahameng sa bokaholimo, empa e lekanyetsoa ke ductility ea alloy mochesong o tlase. Ho thatafala ho finyelloang ka ho fereka ho batang ho susumetsoa ke tekanyo ea khatello e sebelisoang le motsoako oa motsoako. Liphekolo tsa mocheso ka mor'a ho fereka hangata lia hlokahala ho fihlela maemo a thata a lakatsehang le ho imolla khatello ea maikutlo e setseng.
3. Isothermal Forging: Mokhoa ona o tsoetseng pele o kenyelletsa ho forging mochesong o lulang o sa fetohe nakong eohle ea ts'ebetso, hangata haufi le karolo e ka holimo ea mocheso o sebetsang oa motsoako. Isothermal forging e fokotsa likhahla tsa mocheso mme e thusa ho fihlela sebopeho se ts'oanang sa microstructure, se ka ntlafatsang ho thatafala le thepa ea mochini ka kakaretso ea tšepe ea alloy. Ts'ebetso ena e bohlokoa haholo bakeng sa lits'ebetso tse sebetsang hantle tse hlokang lintlha tse hlakileng tsa boima.
Kalafo ea Mocheso le Karolo ea Eona
Ts'ebetso ea ho qhekella feela ha e fane ka qeto ea ho thatafala ha tšepe ea alloy ea ho qetela. Kalafo ea mocheso, ho kenyelletsa ho koala, ho tima, le ho halefisa, ho bohlokoa ho finyella maemo a itseng a thata. Mohlala:
- Annealing: Phekolo ena ea mocheso e kenyelletsa ho futhumatsa tšepe ho mocheso o phahameng ebe o e pholisa butle. Annealing e fokotsa ho thatafala empa e ntlafatsa ductility le ho tiea.
- Ho tima: Ho pholile ka potlako ho tloha mocheso o phahameng, hangata ka metsing kapa ka oli, ho fetola microstructure ea tšepe ho martensite, e leng ho eketsang thata ho thata.
- Ho futhumatsa: Kamora ho tima, ho futhumatsa ho kenyelletsa ho futhumatsa tšepe mocheso o tlase ho lokisa bothata le ho imolla khatello ea maikutlo. Mokhoa ona o leka-lekanya ho thatafala le ho tiea.
Qetello
Kamano pakeng tsa lits'ebetso tsa tšepe ea alloy forging le ho thatafala ho rarahane ebile ho na le mefuta e mengata. Ho fereka ho chesang, ho fereka ho batang, le ho fereka ha isothermal e 'ngoe le e' ngoe e ama ho thatafala ka tsela e fapaneng, 'me boima ba ho qetela bo boetse bo susumetsoa ke liphekolo tse latelang tsa mocheso. Ho utloisisa litšebelisano tsena ho lumella baenjiniere ho ntlafatsa lits'ebetso tsa ho theha ho fihlela boima bo lakatsehang le ts'ebetso e akaretsang ea likarolo tsa tšepe ea alloy. Mekhoa e hlophisitsoeng hantle ea ho theha le ea kalafo ea mocheso e netefatsa hore lihlahisoa tsa tšepe tsa alloy li kopana le litlhoko tse matla tsa lits'ebetso tse fapaneng, ho tloha ho likarolo tsa koloi ho isa likarolo tsa sefofane.
