Abstract
The possibility of melting of ferroniobium from the sublimates of electron-beam remelting of niobium ingots is studied using thermodynamic analysis and a “hot” simulation. The basic requirements for the conditions of processing of sublimates with various (Nb/Al)met ratios are evaluated and determined. A ferroalloy the contents of controlled impurities in which correspond to certain ferroniobium grades of Russian and foreign standards is produced by melting of charges containing the sublimates, a deoxidizer (Fe2O3), and a flux (CaO, CaF2) in an electroslag furnace.
