INCAZELO:
Imishini yokucwenga okusanhlamvu ye-UltrasonicImisebenzi eyinhloko enqubweni yokwelashwa kwe-aluminium yokuncibilika yilezi: ukucwenga okusanhlamvu kwensimbi, ukwakheka kwe-alloy homogenizing, ukuthuthukisa kakhulu amandla nokumelana nokukhathala kwezinto zokuphonsa, 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 ye-liquid igxila kwezinye izindawo.Ngenxa yokudlidliza okunwebekayo kwe-ultrasonic, i-bubble core ikhiqizwa futhi ikhula ngokuqhubekayo ize ikhishwe ensimbi encibilikisiwe.

3. Umthelela wegagasi le-ultrasonic kwikhwalithi yokuphonsa umbungu

Lapho indlela yokuqinisa i-ultrasonic vibration isetshenziselwa ukukhiqiza ama-castings, i-wave ye-ultrasonic izokhiqiza ingcindezi yomsindo eshintshanayo yesibhengezo 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 iwukuba ngcono i-supercooling ephumelelayo yensimbi ewuketshezi.I-nucleus radius ebalulekile iyancipha.Ngakho-ke, izinga le-nucleation liyakhula futhi okusanhlamvu kuyacwengwa.
