INCAZELO:
Imishini yokucwenga okusanhlamvu ye-UltrasonicImisebenzi eyinhloko enqubweni yokwelashwa kwe-aluminium yokuncibilika yilezi: ukucwenga okusanhlamvu kwensimbi, ukwakheka kwe-alloy homogenizing, ukuthuthukisa ngokuphawulekayo amandla nokumelana nokukhathala kwezinto eziphonswayo, ukuthuthukisa izici ezibanzi zezinto zokwakha, ukunciphisa ukusetshenziswa kwezihlungi zokusanhlamvu nokunciphisa izindleko.

1. Ukususwa kokufakwa kwe-Ultrasonic

Kunzima kakhulu ukuthi isisombululo sensimbi sintante kuma-inclusions amancane. Kuphela uma sebebuthana bangantanta phezulu. Lapho ukwelashwa kwe-ultrasonic kwesisombululo se-aluminium, ama-inclusions amancane angafakwa futhi ahlanganiswe. Ngesicwengisisi sokusanhlamvu, izinhlayiya ezinkulu ezifakiwe zintanta ukuze zikhiphe ukungcola.

2. I-Ultrasonic degassing

lapho ukudlidliza okunwebekayo kwethulwa ensimbi encibilikisiwe, i-cavitation phenomenon itholakala, okubangelwa umgodi owenziwe ngemuva kokuphulwa kwesigaba se-liquid, ngakho igesi encibilikisiwe ensimbi ewuketshezi igxila kwezinye izindawo. Ngenxa yokudlidliza okunwebekayo kwe-ultrasonic, i-bubble core iyakhiqizwa futhi ikhule ngokuqhubekayo ize ikhishwe ensimbi encibilikisiwe.

3. Umphumela we-ultrasonic wave kwikhwalithi yokuphonsa umbungu

Lapho indlela yokuqinisa i-ultrasonic vibration isetshenziselwa ukukhiqiza ama-castings, i-wave ye-ultrasonic izokhiqiza ukucindezela komsindo okushintshanayo kwesibhengezo futhi yakhe i-jet. Ngenxa yomphumela ongewona oqondile, ozakwabo bazokhiqiza ukugeleza komsindo nokugeleza komsindo omncane, kuyilapho inkulumo engenalutho ye-ultrasonic izokhiqiza i-jet yesivinini esikhulu esibonakalayo phakathi kokuqina noketshezi. Yonke le miphumela ingasika futhi ibhubhise ama-dendrites, Nomaphi lapho kukhona insimu yomsindo ngaphakathi koketshezi, idlala indima. Ukusebenzisa umphumela we-cavitation kule nqubo, ingahlanza isakhiwo, ihlanze izinhlayiya futhi i-homogenize isakhiwo. Ngaphezu komphumela wemishini obangelwa ukudlidliza ukubhubhisa ama-dendrites, enye indima ebalulekile yokuqinisa ukudlidliza kwe-ultrasonic iwukuthuthukisa ukupholisa okuphumelelayo kwensimbi ewuketshezi. I-nucleus radius ebalulekile iyancipha. Ngakho-ke, izinga le-nucleation liyakhula futhi okusanhlamvu kuyacwengwa.
