钒钛磁铁精矿高负压烧结实践

High negative-pressure sintering of vanadium-titanium magnetite concentrates

通过分析风量和负压对烧结产质量的影响关系,找出钒钛磁铁精矿烧结实施高负压大风量的措施及技术改进实施,360m2烧结机的负压由14 520Pa提高到15 340Pa后,料层提高15mm,利用系数上升0.047t/m2.h,转鼓指数提高0.94%,固体燃耗下降0.82kg/t。

On the basis of analyzing the influence of draft volume and negative pressure on quality ＆ quantity of sinter product, the high negative-- pressure and great draft volume and other improvement measures are adopted in sintering of vanadium--titanium magnetite concentrates. The negative pressure of 300m2 sinter machine is increased from 14520Pa to 15340Pa, which brings result that sintering bed depth increases by 15mm, sinter machine utilization factor increases by 0. 047 t/h, sinter tumbler index raises by 0.94% and solid fuel consumption reduces by 0.82 kg/t.
