Considered are technological and metallurgical peculiarities of melting the titanium alloys in chamber-type electroslag furnaces. Selection of technological diagram of ESR of titanium was grounded, technology of manufacture of consumable electrodes, made of sponge titanium, was described, the problems of selection of a flux composition and modes of melting space gas protection were considered. Titanium alloy ingots were produced in different shapes (cylindrical, hollow, square) and chemical composition. It is shown that by both the quality of metal melted and also the technical-economic characteristics, the ESR can compete with other metallurgical processes of producing the titanium alloy ingots. Ref. 26, Tabl. 1, Fig. 6.

Key words: chamber-type electroslag remelting; titanium alloys; consumable electrode; ingot; flux
