This specialized electron-beam Installation is intended for melting precious metals and precious-metal-based alloys. The plant is provided with an additional internal chamber ("confinement"), which significantly reduces irrecoverable loss of metal in the course of melting.
The high-purity precious metal and alloy production technology is protected by Ukrainian Patent No. 200808911 dd. 17 July 2008.
