Peculiarities of melting of titanium slag from ilmenite concentrate as a substitute for rutile one for applying in welding production are investigated. It is shown that to provide a stable phase composition of the produced titanium slag, avoiding the self-dispersal, it is necessary to maintain a residual amount of iron oxides in it at the level of 5.0 wt.%. Two-stage method of producing the titanium slag with a preliminary hard-phase recovery of iron at the first stage was tested. The titanium slag was produced, containing 80…85 % of titanium oxide, suitable for application in the substitution of rutile concentrate in manufacture of electrodes for welding carbon and low-alloy steels.
