INGCACISO:
Izixhobo zokucokisa ukutya okuziinkozo kwe-ultrasonic's imisebenzi ephambili kwinkqubo yonyango aluminiyam inyibilika zezi: ukusulungekisa iinkozo zentsimbi, ukwakheka ingxubevange homogenizing, ngokuphawulekayo ukuphucula amandla kunye nokumelana nokudinwa kwemathiriyeli yokugalela, ukuphucula iimpawu ezibanzi zemathiriyeli, ukunciphisa ukusetyenziswa abacoci zengqolowa kunye nokunciphisa iindleko.

1. Ukususwa kokufakwa kwe-ultrasonic

Kunzima kakhulu kwisisombululo setsimbi ukudada kwii-inclusions ezincinci.Kuphela kuxa beqokelelene apho banokuthi badada khona.Xa unyango lwe-ultrasonic lwesisombululo se-aluminium, ukufakwa okuncinci kunokuthi kubekwe kwaye kuhlanganiswe.Ngokucoca okuziinkozo, ukufakwa kwamasuntswana amakhulu kudada phezulu ukuze kususwe ukungcola.

2. Ultrasonic degassing

xa i-vibration ye-elastic ingeniswa kwintsimbi etyhidiweyo, i-cavitation phenomenon ifunyenwe, ebangelwa i-cavity eyenziwe emva kokuqhubeka kwesigaba solwelo saphukile, ngoko igesi echithwe kwintsimbi ye-liquid igxininisa kwezinye iindawo.Ngenxa ye-vibration elastic ye-ultrasonic, i-bubble core yenziwa kwaye ikhula ngokuqhubekayo ide ikhutshwe kwintsimbi etyhidiweyo.

3. Impembelelo ye-ultrasonic wave kumgangatho wokuphosa i-embryo

Xa indlela yokuqinisa i-ultrasonic vibration isetyenziselwa ukuvelisa i-castings, i-wave ye-ultrasonic iya kuvelisa i-alternating sound pressure ye-banner kwaye yenza i-jet.Ngenxa yesiphumo esingenasiphelo, oogxa baya kuvelisa ukuhamba kwesandi kunye nokuhamba kwesandi esincinci, ngelixa intetho engenanto ye-ultrasonic iya kuvelisa i-jet ye-speed-speed kwi-interface phakathi kokuqina kunye nolwelo.Zonke ezi ziphumo zinokusika kwaye zitshabalalise i-dendrites, Naphi na apho kukho intsimi yesandi ngaphakathi kolwelo, idlala indima.Ukusebenzisa i-cavitation effect kule nkqubo, inokuhlambulula isakhiwo, ihlambulule iinqununu kunye ne-homogenize isakhiwo.Ukongeza kwimpembelelo yomatshini obangelwa yi-vibration ukutshabalalisa i-dendrites, enye indima ebalulekileyo ye-ultrasonic vibration solidification kukuphucula i-supercooling esebenzayo yensimbi yamanzi.I-nucleus radius ebalulekileyo iyancitshiswa.Ngaloo ndlela, izinga le-nucleation liyenyuka kwaye iinkozo zicocwa.
