Effect of the technological parameters of the melt treatment by a electric pulse current on the mixing process

Abstract

The capacitive storage voltage, the storage capacity, the discharge circuit’s inductance, and the electrode system’s type, along with the pulse current’s strength, are shown to be the important technological parameters defining the character of the electrovortex flows, the magnetic pressure, and the liquid-metal conductor mixing speed during the passing of a pulse current. The most effective system among those investigated for cylindrical conductor treatment is the system “point-to-point” providing the intensive mixing of the melt, a favorable structure, and an improved complex of the mechanical properties of alloys after crystallization.
