Isixhobo sokunyibilikisa isinyithi se-ultrasonic senziwe ngamacandelo e-ultrasonic vibration kunye nejenereyitha ye-ultrasonic: iinxalenye ze-ultrasonic vibration zisetyenziselwa ukuvelisa i-ultrasonic vibration – ingakumbi ibandakanya i-ultrasonic transducer, uphondo lwe-ultrasonic kunye nentloko yesixhobo (intloko ehambisayo), kwaye idlulisele la mandla okungcangcazela kwintsimbi. nyibilika.

Umsebenzi we-ultrasonic metal melt:

1. Ukususa ukungcola: kunzima kakhulu ukubandakanywa okuncinci kwintsimbi engamanzi ukudada phezulu.Kuphela kuxa beqokelelene apho kuya kuba lula ukudada phezulu.Ukusebenzisa i-ultrasonic metal melt izixhobo zonyango ukongeza i-ultrasonic kwisisombululo, i-ultrasonic i-wave wave ingenza i-powder efakwe kwisisombululo se-delamination kunye ne-agglomeration ngempumelelo.

2. I-Ultrasonic degassing: I-ultrasonic inempembelelo enkulu ekususeni igesi kwintsimbi etyhidiweyo.I-ultrasonic vibration elastic inokuphelisa ngokupheleleyo i-alloy kwimizuzu embalwa.Xa i-vibration ye-ultrasonic ifakwe kwintsimbi etyhidiweyo, kufunyenwe ukuba kukho i-cavitation phenomenon, ebangelwa i-cavity eveliswa emva kokuqhubeka kwesigaba samanzi siphukile, ngoko igesi echithwe kwi-metal metal igxininise kuyo.

3. Ukulungiswa kweenkozo: xa uvelisa i-castings nge-ultrasonic vibration solidification method, i-wave ye-ultrasonic iya kuvelisa i-positive kunye ne-negative alternating sound pressure and form jet.Ngexesha elifanayo, ngenxa yempembelelo engabonakaliyo, iya kuvelisa ukuhamba kwesandi kunye nokuhamba kwesandi esincinci, ngelixa i-ultrasonic cavitation iya kuvelisa i-jet ye-high-speed micro jet kwi-interface phakathi kokuqina kunye nolwelo.

Impembelelo ye-cavitation kwi-ultrasonic liquid inokunqumla kwaye itshabalalise i-dendrites, ifuthe i-solication front, ikhulise umphumo wokuvuselela kunye nokusabalalisa, kwaye ihlambulule isakhiwo, ihlambulule ingqolowa kunye ne-homogenize isakhiwo.

Ukongeza kumonakalo womatshini we-dendrites obangelwa yi-vibration, enye indima ebalulekileyo ye-ultrasonic vibration solidification kukuphucula i-undercooling esebenzayo yensimbi yamanzi kunye nokunciphisa i-nucleus radius ebalulekileyo, ukwenzela ukwandisa izinga le-nucleation kunye nokucoca iinkozo.

3. Ukuphucula umgangatho we-slab: Izixhobo zonyango ze-ultrasonic zenyibilika zensimbi zinokusebenza kwi-mold ukuphucula umgangatho we-slab.Ukungcangcazela kwesikhunta nge-ultrasonic ingasetyenziselwa i-billet, i-bloom kunye ne-slab, kwaye akukho sliding engalunganga xa kusetyenziswa i-vibration ye-ultrasonic.Xa uphosa i-billet kunye ne-bloom, i-billet surface egudileyo inokufumaneka emva kokusebenzisa i-vibration ye-ultrasonic kwi-mold.
