ELTECHMACH has developed an industrial electron-beam Installation for refining and melting of material into ingots and blocks. This industrial equipment allows to melt feedstock either directly into the crystallizer or via an intermediate vessel. The feedstock may be in the form of ingots, lumps, rods, and any kind of waste, e.g. compressed chips (shavings).
The equipment yields high-quality ingots and blocks, according to the chemical and phase composition requirements, of high-reactive and refractory metals, such as tungsten, titanium, molybdenum, niobium, hafnium, zirconium, nickel, copper, cobalt and iron; heat-resistant and heatproof alloys, as well as intermetallides such as Ti3AI, TiAl, Ni3AI, NiAI, etc.
The Installation equipped a glow discharge guns with cold cathode.
