High-frequency Quenching ke eng?

Ho tima hangata haholoe sebelisoa haholo bakeng sa ho tima holim'a likarolo tsa tšepe tsa indasteri.Ke mofuta oa tšepe mocheso phekolo mokhoa o etsang hore workpiece holim'a ho hlahisa e itseng induced hona joale, ka potlako futhumatsa holim'a likarolo, 'me joale ka potlako quenching.Induction futhumatsang thepa, ke hore, workpiece induction futhumatsang, e le hore holim'a quenching. thepa.

Molao-motheo oa ho futhumatsa ka induction: Sesebelisoa sa mosebetsi se kenngoa moeeng ka phala ea koporo e se nang letho ka har'a sensor, kamora ho fihlella maqhubu a mahareng kapa maqhubu a phahameng a alternating current (ac), e entsoeng ka holim'a metsi ka makhetlo a hona joale a induced, sebaka sa mosebetsi. kapa ho futhumatsa ka potlako sebakeng (metsotsoana e seng mekae ho mocheso oa 800 ~ 1000 ℃, motheo o ntse o le haufi le mocheso oa kamore) hang ka mor'a metsotsoana e 'maloa ka potlako ho fafatsa (dip) metsi a pholileng (kapa ho fafatsa ho qoelisoa ha oli) ho sebetsa ka ho qoelisoa ka ho feletseng, workpiece bokahodimo kapa selehae ho fihlela ditlhoko tsa boima bo tsamaellanang.

Ha ho bapisoa le ho tima ho futhumatsa ho tloaelehileng, e na le:

1. Lebelo la ho futhumatsa le potlakile haholo, le ka atolosang mocheso oa phetoho ea 'mele oa A le ho khutsufatsa nako ea phetoho.

2. Martensite e ntle haholo ea cryptocrystalline e ka fumanoa holim'a mosebetsi oa ho sebetsa ka mor'a ho tima, 'me ho thatafala ho phahame hanyenyane (2 ~ 3HRC) .Bofokoli bo tlaase le matla a phahameng a mokhathala.

3. Mosebetsi o tšoaroang ka mokhoa ona ha o bonolo ho oxidize le decarbonize, esita le tse ling tsa workpiece li ka bokelloa ka ho toba 'me tsa sebelisoa ka mor'a ho sebetsa.

4, lera le thata le tebile, ho bonolo ho laola ts'ebetso, ho bonolo ho elelloa mochini, othomathike.

5, mocheso holim'a lelakabe o tima

Thibelo e phahameng ea maqhubu e sebelisoa ho sesebelisoa sa mosebetsi se hlokang ho jara ketso ea mojaro o fapanyetsanang joalo ka torsion le ho khumama.E hloka hore bokaholimo bo be le khatello e phahameng ea maikutlo kapa ho hanyetsa ho roala ho feta mantlha, 'me bokaholimo ba mosebetsi bo hloka ho matlafatsoa.E loketse tšepe e nang le carbon content We = 0.40 ~ 0.50%.
