Ultrasonic tekinoroji yakatanga kushandiswa mune zvekurapa mu1950s uye 1960s, asi zvakazoitawo kufambira mberi kukuru.Parizvino, pamusoro pekushandiswa mundima yekurapa, tekinoroji ye ultrasonic yakakura muindasitiri ye semiconductor, indasitiri yemaziso, petrochemical indasitiri uye zvimwe zvinhu, asi inonyanya kushandisa maitiro ayo ekutungamira kwakanaka uye kugona kwakasimba kwekupinda kuita basa rekuchenesa. .

Ultrasonic tekinoroji yave nzira inowedzera kukosha yekusimbisa.Pamusoro pezvishandiso zvataurwa pamusoro apa, ine zvakare yakanakisa yekushandisa mukana mune mamwe minda kuti igadziriswe.

Nheyo ye ultrasonic kusimbisa metallurgical process:

Sezvatinoziva tese, "kuchinjisa kutatu uye kumwe kuita" mumetallurgical process ndicho chinhu chakakosha chinokanganisa mashandiro ekuita, kumhanya uye kugona, uye zvakare inopfupisa maitiro ese ekugadzirwa kwesimbi nemakemikari.Izvo zvinodaidzwa kuti "kuchinjisa katatu" kunoreva kutamiswa kwehuwandu, kukurumidza kufambisa uye kutamisa kupisa, uye "imwe reaction" inoreva maitiro emakemikari kuita.Muchidimbu, nzira yekuvandudza iyo metallurgical process inofanira kutanga nemaitiro ekuvandudza kushanda uye kumhanya kwe "matatu kutapurirana uye imwe reaction".

Kubva pakuona uku, tekinoroji ye ultrasonic inoita basa rakanaka mukusimudzira kutamiswa kwehuwandu, kukurumidza uye kupisa, iyo inonyanya kutsanangurwa neiyo inherent maitiro e ultrasonic.Muchidimbu, kushandiswa kweiyo ultrasonic tekinoroji mune metallurgical process ichave neinotevera mikuru mhedzisiro:

1, Cavitation mhedzisiro

Cavitation mhedzisiro inoreva kusimba kwekukura uye kudonha kweiyo micro gasi core cavitation bubbles iripo muchikamu chemvura (kunyungudika, mhinduro, nezvimwewo) kana kurira kwekurira kwasvika pane imwe kukosha.Munguva yekukura, kuputika uye kupera kwemadiki mabhuru anogadzirwa muchikamu chemvura, nzvimbo dzinopisa dzinoonekwa munzvimbo diki yakatenderedza muchina webubble, zvichikonzera kupisa kwakanyanya uye nzvimbo yekumanikidza kusimudzira maitiro.

2, Mechanical effect

Mechanical mhedzisiro ndiyo mhedzisiro inogadzirwa ne ultrasonic ichienda kumberi mukati mepakati.Iyo yakakwira-frequency vibration uye neradiation pressure ye ultrasonic inogona kuumba kutekenyedza uye kuyerera, kuitira kuti nhungamiro yepakati ipinde munzvimbo yevibration munzvimbo yayo yekuparadzira, kuitira kuti ikurumidze kupararira uye kunyungudika kwezvinhu.Mechanical effect yakasanganiswa nekuzunguzika kwecavitation bubbles, iyo yakasimba jeti uye yemuno kupinza diki inogadzirwa panzvimbo yakasimba inogona kuderedza zvakanyanya kusimba kwepasi uye kukwesha kwemvura, uye kuparadza muganho weiyo solid-liquid interface, kuitira kuti uwane. mhedzisiro iyo yakajairwa yakaderera-frequency mechanicha inobvongodza haigone kuwana.

3, Thermal effect

Kupisa (Thermal effect) zvinoreva kupisa kunoburitswa kana kutorwa nehurongwa huri mukushanduka pane imwe tembiricha.Kana ultrasonic wave ichipararira mukati mepakati, simba rayo rinoramba richibatwa nepakati zvidimbu, kuitira kuti rishandure kuva simba rekupisa uye kukurudzira kupisa kwekushisa mukuita maitiro.

Kuburikidza neiyo yakasarudzika mhedzisiro ye ultrasonic tekinoroji, inogona zvinobudirira kuvandudza kushanda uye kumhanya kwe "matatu kutapurirana uye imwe chete maitiro" mu metallurgical process, kuvandudza mamineral kuita, kuderedza huwandu hwezvakagadzirwa uye kupfupisa nguva yekuita, kuti uwane. chinangwa chekuchengetedza simba uye kuderedza kushandiswa.
