ELP-30,
the most powerful Electron Beam furnace in the world, is installed in
the town of Orsk. Its main equipment supplied by German manufacturers
LEW Hennigsdorf and Von Ardenne Anlagentechnik was later complemented
by that of Yuzhuralmash. The furnace design allows for metals and special
alloys remelting under high vacuum by means of electron beam power.
The complex is capable of producing steel, titanium and copper slabs
and ingots. The ove-rall capacity of the furnace is 4500 tones of steel
ingots with maximum weight of 40 tones each.
The furnace is equipped with the intermediate container (cold-hearth
unit) for metal refining. The furnace enables to remelt lump material
without extrusion and to feed in alloying materials in the process of
blending. High range power adjustment allows to control solidification
of the ingot. If necessary, certain materials can be removed from the
hotmelt.
High vacuum enables to remelt materials, which acidize when heated in
air (titanium, niobium etc.) The furnace is equipped with five electron
beam guns, with maximum capacity 1200 kW each (the adjustable capacity
range is 50-1200 kW), which back up each other.
If two guns fail simultaneously, the furnace continues working in normal
operations mode. If the third gun fails, the furnace still keeps working
and is capable to complete the melting process. From the environmental
point of view, the furnace can be regarded as a safe and pollution-free
melting facility..
