Yini esetshenziselwa i-aluminium ye-ultrasonic?

Imishini ye-Ultrasonic Metal Melt isebenzisa umphumela we-cavitation we-ultrasound in the ukuncibilika ukuze unqume futhi uchithe ama-dendrites, wandise ukuqina, futhi ngasikhathi sinye ukwandisa amandla ezinto zensimbi futhi uthuthukise ubulukhuni bezinsimbi zensimbi. Ama-rains amancane nendawo enkulu yomngcele angavimbela ngempumelelo uku-disloadiation kanye ne-intercrystalline slip, okusho ukuthi kudinga amandla amaningi ukuphula okuqukethwe. Abakwahle baqine, okuncane okuhlukanisayo kwe-dendrite, kuphakama amandla okuvutha, futhi kungcono ubunzima. Isakhiwo se-Ingot esilungile yi-crystal efanayo ne-equidaxed crystal ephakeme kuyo yonke ingxenye yesiphambano ye-Ingot. Lokhu kungenxa yokuthi i-crystal efakiwe ine-anisotropy encane, i-deffortrorm yomfaniswano ngesikhathi sokucubungula, ukusebenza okuhle kakhulu, i-plastiki enhle, futhi kuyasiza ekusebenzeni nasekusetshenzisweni kwepulasitiki okulandelayo. Ukuthola lesakhiwo, indlela engcono kakhulu okwamanje ukusebenzisa imishini yensimbi yensimbi ye-ultrasonic ye-ultrasonic ukwenza ukucolisiswa kwe-ultrasonic kuncibilike.

Ukwelashwa kwe-ultrasonic kwe-aluminium incibilike inqubo esetshenziselwa ukucwilisa i-misftruction yensimbi ngokusebenzisa okuphezulu - amagagasi omsindo wemvamisa. Le ndlela inenzuzo ikakhulukazi embonini ye-aluminium yokusakaza ngenxa yezizathu eziningana:

1. I-Degassing: Amagagasi e-Ultrasonic asiza ekunciphiseni i-aluminium ebindayo ngokuqhakambisa ukukhishwa kwamagesi ancibilikile afana ne-hydrogen no-oxides. Lokhu kuthuthukisa izakhiwo zemishini zokuphonswa kokugcina.

2. Ukuhlaziywa kokuhlwa okusanhlamvu: ukusetshenziswa kwe-ultrasonic vibrations kungakhipha ukucwaswa okusanhlamvu kokuhlaziywa kokusanhlamvu ngensimbi eqinile. Amasayizi amancane okusanhlamvu aholela emandleni okusebenza athuthukisiwe kanye nokuqedwa okungcono kwendawo yezingxenye.

3. I-Homogenization: Kuyasiza ekufezeni ukusatshalaliswa okufanayo kwezinto ezengeziwe zezinto zokushisa kanye nokushisa kulo lonke kuncibilike. Lokhu kuphumela ezizandleni ezingaguquki kulo lonke izinkomba.

4. I-ancishise ipulasi elincishisiwe: ngokuphula amafilimu e-oxide kanye nama-bubble kagesi, ukwelashwa kwe-ultrasonic kunciphisa ubukhona be-porosity e-aluminium esosisekelo, ethuthukisa ubuqotho bokwaziswa.

5. Ukukhohla okuthuthukisiwe: Inqubo ingathuthukisa ukugeleza kwe-aluminium ebiwe, okwenza kube lula ukuphonsa amabumo ayinkimbinkimbi anezinkinga ezimbalwa.

Ukwelashwa okuphelele, kwe-ultrasonic of aluminium incishise inqubo eyinkimbinkimbi enomthelela ekukhiqizweni okuphezulu - Ikhwalithi ye-aluminium enezimpahla ezithuthukisiwe zemishini kanye nokuqedwa komhlaba.
