摘要
针对四川德胜集团钢铁有限公司使用高配比钒钛磁铁精矿烧结生产的情况,在实验室进行了Al2O3对钒钛烧结矿产质量、低温还原粉化以及烧结矿矿物组成和显微结构的试验研究。研究结果表明:Al2O3含量的提高对烧结矿的产、质量以及低温还原粉化指标产生不利的影响,考虑到烧结原料条件及实际生产的需要,烧结矿中Al2O3含量小于3.2%为宜。
As high ratio of V-bearing titaniferous magnetite concentrate is used for the sintering feed in Sichuan Desheng Iron and Steel（Group）Company Ltd.,experiments were carried out at the laboratory to probe into the influence of Al2O3 on production yield and quality,reduction disintegration index at low temperature and mineral composition and microstructure of sinter.The results show that production yield,quality and reduction disintegration index at low temperature of sinter tend to downgrade with the increase of Al2O3 content.Considering the actuality of sintering feedstock and the production need of Sichuan Desheng Iron and Steel（Group）Company Ltd.,Al2O3 content in sinter must be kept within 3.2%.
