摘　　要：随着精料水平的提高,高炉生产指标明显改善,但也带来了一些问题,如:烧结料SiO_2含量偏低,粘结相不足,导致烧结矿强度降低;(Al_2O(?))含量升高,炉渣流动性差;偏面追求高熟料比等。针对这些问题,并结合一些企业的生产实践,作者提出了解决问题的对策。By improving beneficiated material standard .the production indexes of BF are obviously improved, but some new problems have arisen, such as sinter strength lowers with SiO2 in sinter material lowering, slag fluidity lowers with (Al2O3) increasing, high agglomeration rate is emphasised. Some countermeasures to solve these problems have been put out.
