摘　　要：在焦炭性能和高炉风量基本保持稳定的背景下,含铁炉料在还原条件下的熔化性能是影响高炉软熔带和透气性最重要的因素.为满足高炉炉料结构快速变化的需要,采用还原反应熔化参数来表征不同炉料结构的性能,进行还原条件下熔化实验和荷重熔滴实验,探究还原熔化参数与荷重熔滴特征值的关联性.实验结果表明还原熔化参数和荷重熔滴特征值有很好的一致性.而还原熔化实验周期短、人力成本低、物力成本低,参照荷重熔滴实验结果,可快速为高炉确定合理炉料结构提供指导.The melting properties of iron-bearing charges under reduced conditions was the most important factor affecting cohesive zone and permeability in blast furnace,given basically stable coke performance and air volume.In order to meet the needs of rapidly changing blast furnace charge structure,this paper uses reducing-melting parameters to characterize the performance of different burden structures.At the same time,melting experiment and the load-drip experiment were carried out under reducing conditions to explore the correlation between reducing-melting parameters and the eigenvalue of droplet under load.The experimental results showed that reducing-melting parameters were in good agreement with the droplet eigenvalue under load.Featuring short cycle and low cost of manpower and material resources,the results of reducing-melting experiment,along with that of the load-bearing droplet experiment,can quickly provide guidance for determining the reasonable blast furnace burden structure.
