A ladle, process, and system for casting an aluminum-based alloy includes a casting ladle. The casting ladle includes a cup and the cup defines an opening. The ladle also includes an ultrasonic transducer including an end immersed in the cup, wherein the cup exhibits a first depth and the ultrasonic transducer is immersed in the cup at a second depth in a range of 5 percent to 100 percent of the first depth. An aluminum-based alloy melt is introduced into an opening of a casting ladle, an ultrasonic transducer immersed in the aluminum-based alloy melt is activated, and the aluminum-based alloy melt is transferred onto a casting surface.
