攀枝花钒钛磁铁矿钠化浸钒球团在还原过程中有着特殊的膨胀、破损规律。实验室研究表明,在回转窑直接还原过程中可以采用予还原—深度还原方案得以解决,并确定了合适工艺参数。在半工业试验中证明,按此方案可以获得优质金属化球团,基本上解决了球团粉化,实现了较长期的稳定运行,技术指标较好。 本文还从理论上分析了球团还原粉化、球团还原、脱硫机理以及窑衬粘结的原因等,提出了相应的改善和予防措施。

Panzhihua vanadium titanium magnetite vanadium-bearing vanadium pellets in the reduction process has a special expansion, damage rules. Laboratory studies show that in the process of direct reduction of rotary kiln can be used to restore the depth reduction program to be resolved, and to determine the appropriate process parameters. In the semi-industrial test proved that, according to this program can get high-quality metal pellets, pellets basically solved the problem, to achieve a more stable long-term operation, technical indicators better. This paper also theoretically analyzed the pellet reduction chalking, pellet reduction, desulfurization mechanism and kiln lining adhesion reasons, put forward the corresponding improvements and preventive measures.
