INGCACISO:
Izixhobo zokucokisa ukutya okuziinkozo kwe-ultrasonic's imisebenzi ephambili kwinkqubo yonyango aluminiyam inyibilika zezi: ukusulungekisa iinkozo zentsimbi, ukubunjwa ingxubevange homogenizing, ngokubonakalayo ukuphucula amandla kunye nokumelana nokudinwa kwemathiriyeli yokugalela, ukuphucula iimpawu ezibanzi zemathiriyeli, ukunciphisa ukusetyenziswa abacokisi ukutya okuziinkozo 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 ke igesi echithwe kwi-metal metal igxininise kwezinye iindawo. Ngenxa ye-elastic vibration ye-ultrasonic, i-bubble core yenziwe 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.
