Working Principle and Characteristics of Vacuum Consumable Arc Furnace (VAR)

The world's first vacuum consumable arc furnace was born in the United States in 1950. A vacuum consumable arc furnace is an electric furnace that uses the energy of an electric arc to melt metal in a vacuum chamber. Vacuum consumable arc furnaces are mainly used to melt active metals and refractory metals such as titanium, zirconium, and molybdenum, and are also used to melt heat-resistant steel, stainless steel, tool steel, and bearing steel. In the early 1950s, it was used to remelt high-temperature alloys, showing excellent superiority and becoming one of the important means of remelting high-temperature alloys and special steels.
