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 in close proximity to the ultrasonic device.

摘要: Devices may be in contact with molten metals such as copper, for example. The devices may include, but are not limited to, a die used for producing articles made from the molten metal, a sensor for determining an amount of a dissolved gas in the molten metal, or an ultrasonic device for reducing gas content (e.g., hydrogen) in the molten metal. Niobium may be used as a protective barrier for the devices when they are exposed to the molten metals.
