Theknoloji ea Ultrasonic e ile ea qala ho sebelisoa lefapheng la bongaka lilemong tsa bo-1950 le bo-1960, empa hape e ile ea tsoela pele haholo.Hajoale, ntle le ts'ebeliso lefapheng la bongaka, theknoloji ea ultrasonic e se e hōlile indastering ea semiconductor, indasteri ea optical, indasteri ea petrochemical le likarolo tse ling, empa haholo-holo e sebelisa litšobotsi tsa eona tsa tataiso e ntle le bokhoni bo matla ba ho kenella ho etsa mosebetsi oa ho hloekisa. .

Theknoloji ea ultrasonic e fetohile mokhoa oa bohlokoa ka ho fetisisa oa ho matlafatsa.Ntle le lits'ebetso tse boletsoeng ka holimo, e boetse e na le bokhoni bo botle ba ts'ebeliso mafapheng a mang a lokelang ho ntlafatsoa.

Molao-motheo oa ts'ebetso ea ultrasonic e matlafatsang metallurgical:

Joalokaha bohle re tseba, "li-transfers tse tharo le karabelo e le 'ngoe" ts'ebetsong ea metallurgical ke ntho ea bohlokoa e amang ts'ebetso ea ts'ebetso, lebelo le bokhoni, hape e akaretsa ts'ebetso eohle ea tlhahiso ea metallurgical le lik'hemik'hale.Seo ho thoeng ke "li-transfers tse tharo" li bua ka ho fetisoa ka bongata, ho fetisoa ka matla le ho fetisoa ha mocheso, 'me "karolo e le' ngoe" e bolela ts'ebetso ea lik'hemik'hale.Ha e le hantle, mokhoa oa ho ntlafatsa ts'ebetso ea metallurgic e lokela ho qala ka mokhoa oa ho ntlafatsa katleho le lebelo la "phetiso e meraro le karabelo e le 'ngoe".

Ho latela pono ena, thekenoloji ea ultrasonic e phetha karolo e ntle ho khothalletsa ho fetisoa ha boima, matla le mocheso, oo haholo-holo o khethiloeng ke litšobotsi tsa tlhaho tsa ultrasonic.Ka kakaretso, ts'ebeliso ea theknoloji ea ultrasonic ts'ebetsong ea metallurgical e tla ba le litlamorao tse tharo tse latelang:

1, phello ea cavitation

Cavitation effect e bolela ts'ebetso e matla ea ho hōla le ho putlama ha li-bubble tsa micro gas core cavitation tse teng karolong ea mokelikeli (qhibiliha, tharollo, joalo-joalo) ha khatello ea molumo e fihla ho boleng bo itseng.Nakong ea kholo, ho phatloha le ho fela ha li-bubble tse nyenyane tse hlahisoang karolong ea mokelikeli, libaka tse chesang li hlaha sebakeng se senyenyane se pota-potileng mochine oa bubble, e leng se bakang mocheso o phahameng le sebaka se phahameng sa khatello ho khothalletsa karabelo.

2, phello ea mochine

Mechanical effect ke phello e hlahisoang ke ultrasonic e tsoelang pele ho ea bohareng.The high-frequency vibration le radiation pressure ea ultrasonic e ka etsa pherekano e sebetsang hantle le ho phalla, e le hore tataiso e bohareng e ka kena sebakeng sa ho sisinyeha sebakeng sa eona sa ho ata, e le ho potlakisa ts'ebetso ea ho hasana le ho qhibiliha ha lintho.Mechanical effect e kopantsoeng le ho sisinyeha ha li-bubble tsa cavitation, jete e matla le micrompingement ea sebakeng seo e hlahisoang holim'a metsi a tiileng e ka fokotsa tsitsipano ea holim'a metsi le likhohlano tsa mokelikeli, 'me ea senya moeli oa sebopeho se tiileng-metsi, e le ho finyella. phello e tloaelehileng e tlaase-frequency mechanical e tsosang takatso e ke keng ea e finyella.

3. Phello ea mocheso

Phello ea mocheso e bolela mocheso o lokolloang kapa o kenngoa ke tsamaiso nakong ea phetoho mocheso o itseng.Ha ultrasonic wave propagates in the medium, matla a eona a tla tsoela pele ho kenngoa ke likaroloana tse mahareng, e le ho e fetola matla a mocheso le ho khothalletsa ho fetisoa ha mocheso ts'ebetsong ea karabelo.

Ka phello e ikhethang ea theknoloji ea ultrasonic, e ka ntlafatsa ka katleho katleho le lebelo la "phetisetso e meraro le karabelo e le 'ngoe" ts'ebetsong ea metallurgical, ho ntlafatsa ts'ebetso ea liminerale, ho fokotsa bongata ba lihlahisoa tse tala le ho khutsufatsa nako ea ho itšoara, e le ho finyella. sepheo sa ho baballa matla le phokotso ya tshebediso.
