降低炼钢全流程钢铁料消耗综合技术研究

Study on Technologies of Reducing Ferrous Materials Consumption throughout Steelmaking Process

结合攀钢提钒炼钢厂装备及工艺条件,详细分析了影响钢铁料消耗的因素,提出优化脱硫提钒工艺,降低脱硫提钒铁损;优化复吹炼钢,减少渣中带铁,降低终渣TFe;加强连铸管理,提高单中包连浇炉数、优化切割等降低钢铁料消耗的主要技术措施并应用于生产,取得了降低钢铁料消耗4.79 kg/t的效果。

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.
