钒钛磁铁精矿低硅烧结强化试验与应用

Test & application of intensive low-silicon sintering of vanadium-titanium magnetite concentrate

钒钛磁铁矿低硅烧结试验表明,由于液相量减少而使烧结矿强度下降,低温还原粉化恶化,产质量指标变差。采用提高碱度、添加硼化物、使用活性灰、提高料层厚度等措施均可强化烧结,减轻SiO2的影响,其综合焦比下降的效果明显。

The test of low-silicon sintering of vanadium-titanium magnetite concentrate shows that the strength of sinter decreases due to liquid phase qty decrease,the low temperature breakdown index becomes deteriorated,and the quantitative qualitative index changes worse.The measures such as increasing the basicity,adding boride and active ash and increasing bed thickness can intensify the sintering process and reduce the influence of SiO2.
