L-9 Electron-beam Installation for Melting Refractory Metals

 

This plant is intended for melting the feedstock in the form of powder, pellets, lumps, cylinder-shaped billets and compact billets into solid ingots or rectangular-shaped plates.

The plant is designed in two options: one uses electron-beam guns with filament type cathode and the other uses 100 kW gas-discharge guns with cold cathode.
