In consideration of equipments and production process in the vanadium recovery ＆ steelmaking plant of Pangang,the influencing factors of ferrous materials consumption in steel production process have been analyzed.On this basis,the processes of desulphurization and V-extraction are optimized to reduce the iron loss during desulphurization and V-extraction.Converter steelmaking processes are optimized as well to reduce the content of TFe in slag.Furthermore,the management of continuous casting process is strengthened to increase the sequence casting heats in a single tundish and optimize the cutting process.With these countermeasures,the ferrous materials consumption in steel production is reduced by 4.79 kg/t.
