The paper presents the history of flux-cored wires appearance and their application as remelted material, both in micrometallurgy (surfacing), and in large-scale metallurgy (electroslag remelting and foundry). Features of technological processes with flux-cored wire application in each of the considered branches are shown. At present technologies ensuring improvement of metal quality in foundry are developing the most actively. Prospects for flux-cored wires application in surfacing from the viewpoint of improvement of their production technology and development of new compositions of deposited metal have largely been exhausted. Technologies of surfacing in a current-supplying mould have certain potential for a wider application, particularly in the field of producing composite layers. Electroslag remelting of metal, as in the years of its development, is mainly focused on producing ingots of a large mass and diameter with application of monolithic electrodes of a large cross-section. 37 Ref., 1 Table, 5 Figures.
