Vacuum Arc Remelting Furnace

Description
Vacuum arc remelting furnace, this is a consumable electrode remelting process performed inside a vacuum chamber. Exposure of molten metal droplets to vacuum reduces free gas content in the steel providing a cleaner product with little segregation.

Features
1. The VAR process involves the melting of an electrode by a controlled DC arc in a vacuum environment.
2. The arc is established between the negative consumable electrode (cathode) and the crucible base (anode) and quickly forms a molten pool of metal.
3. The gap between the melting electrode and metal pool (arc gap) is precisely maintained and a controlled melt rate is established.
4. An advanced computer control system maintains the melt rate and arc gap utilizing custom designed algorithms taking into account measurements from the load beam weighing system, measurements of the furnace voltage, and measurements of the number of drip (drop) shorts.
