Ngwá ọrụ nhazi ọka ultrasonic's isi ọrụ na usoro nke aluminum gbazee ọgwụgwọ bụ: refining metal grains, homogenizing alloy mejupụtara, budata mma ike na ike ọgwụgwụ na-eguzogide nke nkedo ihe, melite keukwu Njirimara nke ihe, mbenata ojiji nke ọka refiners na mbenata ụgwọ.

1. Mwepụ nsonye nke ultrasonic

Ọ na-esiri ike maka ngwọta ígwè ka ọ na-ese n'elu obere ntinye. Naanị mgbe ha gbakọtara ka ha nwere ike feli elu. Mgbe ọgwụgwọ ultrasonic nke ngwọta aluminom, obere ntinye nwere ike ịkwado na ikpokọta. Site na onye na-anụcha ọka, nnukwu ihe ntinye ihe na-ese n'elu iji wepụ adịghị ọcha.

2. Ultrasonic degassing

mgbe a na-ewebata vibration na-agbanwe n'ime ígwè a wụrụ awụ, a na-ahụ ihe dị egwu cavitation, nke bụ n'ihi oghere a na-emepụta mgbe a na-agbaji usoro mmiri mmiri na-aga n'ihu, ya mere gas na-agbaze na mmiri mmiri na-etinye uche na ebe ndị ọzọ. N'ihi ụda na-agbanwe agbanwe nke ultrasonic, a na-emepụta isi afụ ahụ ma na-eto eto na-aga n'ihu ruo mgbe enwere ike ịpụ ya na ígwè a wụrụ awụ.

3. Mmetụta ultrasonic ebili mmiri na àgwà nkedo ẹmbrayo

Mgbe a na-eji usoro siri ike nke ultrasonic vibration na-emepụta ihe nkedo, ụda ultrasonic ga-emepụta nrụgide ụda ọzọ nke ọkọlọtọ wee mepụta jet. N'ihi mmetụta na-adịghị ahụkebe, ndị ọrụ ibe ga-emepụta ụda ụda na ụda ụda micro, ebe ultrasonic efu okwu ga-emepụta jet dị elu na interface n'etiti siri ike na mmiri mmiri. Mmetụta ndị a niile nwere ike igbutu ma bibie dendrites, Ebe ọ bụla enwere ụda ụda n'ime mmiri mmiri, ọ na-ekere òkè. N'iji mmetụta cavitation na usoro a, ọ nwere ike ime ka usoro ahụ dị ọcha, mee ka ihe ndị ahụ dị ọcha na homogenize usoro ahụ. Na mgbakwunye na mmetụta arụ ọrụ nke na-eme site na vibration na-ebibi dendrites, ọrụ ọzọ dị mkpa nke ultrasonic vibration solidification bụ iji melite mma supercooling nke mmiri mmiri metal. A na-ebelata radius oghere dị egwu. Ya mere, ọnụọgụ nucleation na-abawanye ma na-anụcha ọka.
