Induction annealing ke eng?
Induction annealing ke karolo ea ho futhumatsa ka induction. Sepheo sa induction annealing ke ho fetola ho thatafala ha thepa ea tšepe, ho tiea le khatello ea kelello e ka hare e le ho finyella thepa e ntle ka ho fetisisa. Monyetla o ka sehloohong oa induction annealing ke hore workpiece e ka futhumatsoa ka mokhoa o lebisitsoeng le o ka phetoang ho netefatsa sephetho se tšoanang kamehla. Hobane mocheso o hlahisoa ka kotloloho setsing sa mosebetsi ka ho fapanyetsana sebaka sa motlakase nakong ea ho kenya letsoho, ts'ebetso e ka laoloa ka nepo mme ts'ebetso e phahameng e ka fihlelleha ka tšebeliso e nepahetseng ea matla. Sena se tiisa kabo ea mocheso o ts'oanang le botebo ba ho kenella ha workpiece. Ts'ebetsong ea induction annealing, ha ho pholiso ea tšohanyetso ka metsi kapa se pholileng joalo ka ha ho tima, empa mocheso oa sesebelisoa o fokotseha butle. Ts'ebetso eohle ea ho futhumatsa ha e kopane ebile e khuts'oane.
Ke Hobane'ng ha U Sebelisa Induction Annealing?
Thepa ea thepa ea tšepe e ka ntlafatsoa ka nepo le ka ts'epo ka ho kenya annealing. Induction annealing e sebelisoa haholo bakeng sa ho nolofatsa le ho fokotsa khatello ea maikutlo, e nang le melemo e meholo ha e bapisoa le ts'ebetso ea setso. Ka induction annealing, litšila tse ka har'a lintho tse bonahalang li ka tlosoa ka phekolo ea mocheso nakong ea annealing e hloekileng.
- Ka induction, annealing process ka fokotsa ho thatafala ha tšepe, le ho ntlafatsa polasetiki, e le ho thusa ho itšeha le ho sebetsa ha serame.
- Hloekisa lijo-thollo, felisa mefokolo microstructure bakoang ke ho lahla, forging, 'me tjheseletsa, esita le microstructure le ho hlophisoa ha tšepe, ntlafatsa thepa ea tšepe kapa lokisetsa bakeng sa microstructure ea kalafo hamorao mocheso.
- Felisa khatello ea kelello ka hare ho tšepe ho thibela ho senyeha le ho senya.
Induction annealing e fana ka taolo e ntle ea ho futhumatsa hobane ts'ebetso e ka laoloa ka mokhoa o phethahetseng ka makhetlo, matla, le (bona brazing) nako ea ho kenya letsoho ho latela thepa e lakatsehang. Sena se tiisa boleng bo phahameng haholo ba kalafo ea mocheso le ho pheta-pheta, e leng bohlokoa haholo tlhahisong ea bongata.
Lits'ebetso le Ts'ebeliso ea Ts'ebetso ea Steel Induction ke life?
Mekhoa e tloaelehileng ea ho kenya li-annealing e kenyelletsa homogenization annealing, annealing e feletseng, annealing e sa phethoang, isothermal annealing, spheroidization annealing, recrystallization annealing, annealing annealing, joalo-joalo.
