Claims
- 1. A process for improving the rate of metal production in a steelmaking process which uses FeO containing slag having added Fe-C metal droplets comprising discharging a charge build-up in the slag and adding to the FeO containing slag a transition metal oxide in an amount sufficient to increase electronic conductivity and thereby increasing the reduction rate of FeO in the slag.
- 2. The process of claim 1 wherein the transition metal oxide is selected from the group consisting of TiO.sub.2, Ta.sub.2 O.sub.5, Nb.sub.2 O.sub.5, and mixture thereof.
- 3. The process of claim 1 wherein the transition metal oxide is TiO.sub.2.
- 4. The process of claim 1, wherein the amount of transition metal oxide is an amount sufficient to increase the reduction rate of FeO by up to about 25%.
