Computational Investigation on the Effects of Arc Location in Vacuum Arc Remelting

Creator:

Soler, Miguel

Abstract:

Vacuum arc remelting (VAR) is a secondary melting process for exotic alloys. The main purpose of this process is to increase the input ingot’s physical and chemical homogeneity. This is accomplished through the application of a high current that melts the material through the emergence of electrical arcs that induce...

Investigating arc behavior in a DC vacuum arc remelting furnace using magnetic flux density measurements

Creator:

Woodside, Rigel

Abstract:

The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...
