鞍钢球团生产工艺的发展与高炉炉料结构的进步

Development of Pellet Production Technique and BF Burden Structure in Angang

介绍了鞍钢球团生产系统从“七五”到“十五”的技术改造(从隧道式焙烧机方团矿的生产到带式焙烧机和链箅机-回转窑的全面推广),通过引进和开发球团生产新技术,使球团矿技术经济指标明显改善。高炉从使用单一的自熔性烧结矿到现在的高碱度烧结矿搭配酸性球团矿的合理炉料结构,高炉技术指标实现了质的飞跃。

Technical modernization of pellet production System from the Seventh Five-year Plan to the Tenth Five-year Plan in Angang is introduced（from producing square pellet in tunnel pelletizing machine till overall popularzing belt one and grate kiln）. Technical and economic indexes of pellet are obviously increased due to import and develop new technique for producing pellet. The technological index of BF is greatly raised after tinter with high basieity combining acid pellet instead of single self-fluxed sinter in BF.
