Remelting Variations Under Vacuum I I I + supply

Remelting Variations Under Vacuum Apart from the remelting of a consumable electrode in a water-cooled copper crucible, there is a recent development of the vacuum arc remelting process, namely vacuum arc double electrode remelting (VADER). Fig- ure 5 shows the basic design of the VADER...<<more>>

Vacuum arc remelting - Wikipedia

This cylinder, referred to as an electrode is then put into a large cylindrical enclosed crucible and brought to a metallurgical vacuum (0.001–0.1 mmHg or 0.1–13.3 Pa). At the bottom of the crucible is a small amount of the alloy to be remelted, which the top electrode is brought close to prior to starting the melt....
