铁矿石的高温软熔滴落性能影响高炉内软熔带的形状及位置,进而影响高炉操作的稳定顺行。国内外传统的铁矿石熔滴检测设备存在坩埚尺寸小,试样量少等问题,导致无法客观地模拟高炉实际生产中复杂的炉料结构,同时试验结果波动较大,重现性差。使用大型铁矿石熔滴检测设备,测定了不同炉料结构下含铁炉料的高温软熔滴落特性,同时对比了传统小型熔滴检测设备,结果表明,随着块矿使用比例的增加,大型铁矿石熔滴检测设备测定的炉料的滴落温度td值随之减低,熔滴特征值S值呈相反规律;试验过程中料层出现的压差ΔP值达到峰值后呈现一定幅度的动态变化,初渣试样主要成分为黄长石类矿物及硅酸二钙（C2S）等,且料层的收缩率ΔH值明显增大,符合炉内铁矿石还原过程的生产实际。
