摘要: 通过某钢厂实际生产情况对烧结料层进行物料平衡与热平衡计算，研究分析固体燃料分层添加理论方案，从料层顶部至底部依次配比为4.9%、4.3%、3.7%，进而提出固体燃料分层添加的均热烧结方法。利用CFD软件进行数值模拟并利用烧结杯试验验证。以普通烧结过程作为对比试验，对提出的均热燃烧方式进行验证，研究烧结矿成品率、利用系数、转鼓强度、固体燃料消耗和粒径影响。固体燃料分层配比均热烧结方法除可降低固体燃料消耗外，还可以提升利用系数，增大转鼓强度，提高烧结矿成品率。
Abstract: Through a practical production situation, material balance and heat balance of sintering material were calculated. The ratio of solid fuel additives in theory was 4.9%, 4.3% and 3.7% from top to bottom. Then, heat-balanced sintering method was proposed. Numerical simulation is conducted by CFDs, and experimental verification is settled by sintering cup. Comparing the proposed heat- balanced sintering method with normal sintering method, sinter yield, utilization coefficient, the strength of drum, the solid fuel consumption and particle size effects are studied. New method reduced the consumption of solid fuel, meanwhile improved utilization coefficient and sinter yield, and increased the drum strength.
