Imishini yokucubungula insimbi ye-ultrasonic yenziwe ngezingxenye zokudlidliza ze-ultrasonic kanye nejeneretha ye-ultrasonic: izingxenye zokudlidliza ze-ultrasonic zisetshenziselwa ukukhiqiza ukudlidliza kwe-ultrasonic - ikakhulukazi okuhlanganisa i-ultrasonic transducer, uphondo lwe-ultrasonic kanye nekhanda lamathuluzi (ikhanda elidluliselayo), futhi lidlulisele la mandla okudlidliza ensimbi. ncibilika.

Umsebenzi we-ultrasonic metal melt:

1. Ukukhipha ukungcola: kunzima kakhulu ukuthi izinto ezincane ezifakwe ensimbi ewuketshezi zintante phezulu. Kuphela uma sebebuthana lapho kuzoba lula ukuntanta phezulu. Ukusebenzisa imishini yokwelapha ye-ultrasonic metal melt ukwengeza i-ultrasonic esixazululweni, i-ultrasonic igagasi elimile lingenza ukufakwa kwe-powder ku-delamination yesisombululo kanye ne-agglomeration ngempumelelo.

2. I-Ultrasonic degassing: I-ultrasonic inomthelela omkhulu ekukhipheni igesi ensimbi encibilikisiwe. Ukudlidliza okunwebeka kwe-Ultrasonic kungaqeda ngokuphelele ingxubevange emizuzwini embalwa. Lapho ukudlidliza kwe-ultrasonic kwethulwa ensimbi encibilikisiwe, kutholakala ukuthi kukhona i-cavitation phenomenon, okubangelwa i-cavity ekhiqizwa ngemva kokuqhubeka kwesigaba se-liquid ephukile, ngakho-ke igesi encibilikisiwe ensimbi ye-liquid igxila kuyo.

3. Ukulungiswa kokusanhlamvu: lapho kukhiqizwa ukukhishwa ngendlela yokuqinisa ukudlidliza kwe-ultrasonic, igagasi le-ultrasonic lizokhiqiza ukucindezela komsindo okushintshana okuhle nokubi kanye nejethi lefomu. Ngesikhathi esifanayo, ngenxa yomphumela ongewona oqondile, uzokhiqiza ukugeleza komsindo nokugeleza komsindo omncane, kuyilapho i-ultrasonic cavitation izokhiqiza i-high-speed micro jet esibonakalayo phakathi kokuqinile noketshezi.

Umphumela we-cavitation oketshezini lwe-ultrasonic unganqamula futhi ubhubhise ama-dendrites, uthinte i-solication front, ukwandisa umphumela wokugqugquzela nokusabalalisa, futhi uhlanze isakhiwo, ucwenge okusanhlamvu futhi wenze i-homogenize isakhiwo.

Ngaphandle kokulimala komshini wama-dendrites okubangelwa ukudlidliza, enye indima ebalulekile yokuqinisa ukudlidliza kwe-ultrasonic ukuthuthukisa ukupholisa okusebenzayo kwensimbi ewuketshezi futhi kunciphise i-nucleus radius ebalulekile, ukuze kwandiswe izinga le-nucleation futhi kucwengisiswe okusanhlamvu.

3. Thuthukisa ikhwalithi ye-slab: Imishini yokwelapha ye-ultrasonic metal melt ingasebenza esikhunjeni ukuze kuthuthukiswe ikhwalithi ephezulu ye-slab. Ukudlidliza kwesikhunta nge-ultrasonic kungasetshenziselwa i-billet, i-bloom kanye ne-slab, futhi akukho ukushelela okungalungile lapho kusetshenziswa ukudlidliza kwe-ultrasonic. Lapho uphonsa i-billet kanye nokuqhakaza, indawo ye-billet ebushelelezi kakhulu ingatholakala ngemva kokufaka ukudlidliza kwe-ultrasonic esikhunjeni.
