Research on Application of Vanadium Extraction Tailings for BOF Steelmaking


Article Preview

In order to solve the environmental problems produced by vanadium extraction tailings of calcium roasting, the technology of vanadium extraction tailings used for converter steelmaking is investigated. The research results show that for common steel production, the technology of BOF slagging with vanadium extraction tailings is feasible. Compared with the original complex slagging flux, slag formation times is shortened, rate of dephosphorization, oxygen blowing time, iron loss and so on are slightly better after addition of vanadium extraction tailings. And only the sulfur content of molten steel increased 0.004% and the temperature reduced 10°C. In addition, there is no significant adverse impact on the quality of molten steel.
