Beschreibung
Zusammenfassung:	An ultrasonic transfer device is disclosed. According to one embodiment of the present invention, the ultrasonic transfer device comprises: an oscillation portion outputting an AC voltage; an ultrasonic vibrator vibrating according to the AC voltage; a sensing portion sensing power or current consumed in the ultrasonic vibrator; and an oscillation control portion determining whether or not the ultrasonic vibrator is immersed in molten metal based on a detected result of the sensing portion and starting a control to regulate the frequency of the AC voltage outputted from the oscillation portion so that the ultrasonic vibrator vibrates in accordance with predetermined reference power. 교류 전압을 출력하는 발진부; 교류 전압에 따라 진동하는 초음파 진동자; 초음파 진동자에서 소모되는 전력 또는 전류를 검출하는 센싱부; 및 센싱부의 검출 결과에 기초하여, 초음파 진동자가 금속 용탕으로 침지되었는지 여부를 판단하고, 초음파 진동자가 금속 용탕에 침지된 것으로 판단되면, 기 설정된 기준 전력에 따라 초음파 진동자가 진동하도록 발진부에서 출력되는 교류 전압의 주파수를 조절하는 제어 구동을 시작하는 발진 제어부를 포함하는 것을 특징으로 하는 본 발명의 일 실시예에 따른 초음파 전달 장치가 개시된다.
