ELECTRON BEAM FURNACE

PRODUCTION TECHNOLOGY

The electron-beam furnace of GfE is mainly used for the production of ultra-purified vanadium. The feed stock material vanadium-aluminum is transferred to the electron-beam furnace for refinement after aluminothermic reduction. In the high vacuum of the furnace, an electron-beam is generated and directed toward the material to be melted. The material is melted and drops into a copper mold.
 
Repeated melting leads to a vaporization of impurities in the high vacuum, thus refining the material. GfE uses this process to manufacture ultra-purified vanadium for the chip industry (V 99.9%). In general, it is possible to melt metals with melting points approaching 3,000°C.
