摘要:
E dispositivo integra un sonotrodo (102) susceptible de producir un movimiento oscilatorio mediante un transductor (101) para generar unas ondas de oscilación de ultrasonidos dentro de dicho caldo de aleaciones ligeras, al estar en contacto dicho sonotrodo ( 102) y dicho caldo, para realizar la desgasificación; y un componente electrónico-mecánico (104; embebido en una parte del sonotrodo (102) para detección del estado de vida útil o de una anomalía del sonotrodo (102). El componente electrónico-mecánico (104) incluye medios para el envió de una o mes señales de notificación a un equipo electrónico de control (103), remoto, que junto con el dispositivo constituye un sistema. El dispositivo electrónico de control (103) esta configurado para el envío de una señal de activación o desactivación de dicho transductor (101) tomando en consideración dicha una o más señales de notificación.
摘要:
A method for treating a silver-containing zinc alloy, the method comprising treating the alloy in a process vessel under conditions of elevated temperature and sub-atmospheric pressure so as to selectively vaporise the zinc, providing a filter through which the vaporised zinc passes prior to contacting a condensing surface on which the vaporised zinc condenses to solid zinc, and continuing to treat the alloy until a desired level of dezincing is achieved.

본 발명은 마그네슘 스크랩을 이용한 저니켈 재활용 마그네슘 합금의 제조 방법에 관한 것으로서, 더욱 상세하게는 용해된 마그네슘 스크랩에 Al 및 미시메탈을 첨가하여 Ni-Al-미시메탈 3상 합금 또는 이의 클러스터를 형성하고, 이를 형성된 Ni-Al-미시메탈 3상 합금 또는 이의 클러스터를 중력을 이용하여 분리 제거함으로써 니켈의 함량이 감소된 재활용 마그네슘 합금을 제조할 수 있다.
摘要:
Methods for degassing and for removing impurities from molten metals are disclosed. These methods can include operating an ultrasonic device in a molten metal bath, and adding a purging gas into the molten metal bath through the tip of the ultrasonic device.
摘要:
A thermal system for separating out co-mingled metals in almost pure form, the system including a tunnel kiln having temperature zones through which the co- mingled metals are conveyed and progressively heated until at least one metal of the co-mingled metals melts thereby separating the melted metal from the other metal or metals of the co-mingled metals. The system includes molten metal catch basins for collecting the melted metal which are arranged beneath a conveyor on which the co -mingled metals are transported within the kiln. The catch basins are tapped to the outside of the kiln so that as the various metals melt out at progressively higher temperatures, they can be collected into cast iron chills to form pure ingots.
