HHV’s Vacuum Arc Re-melting furnace has two melt stations – one for consumable (in vacuum) and the other for non-consumable (in sub-atmosphere argon pressure) melting. The furnace is used to melt Niobium and Tantalum as well as to prepare alloys based on these refractory metals with an ultimate objective of producing alloy ingots of 60 – 150 mm diameter and upto 500mm length and alloy pancakes of 110mm diameter and 10mm thickness.
