【摘要】 使用专门开发的实验设备研究了一解剖高炉中烧结矿在熔化后还原过程中的起泡行为，并探讨了影响起泡行为的各种因素。烧结矿的起泡能力随高炉中已达到的还原度的增加而降低。熔渣碱度在０．７～１．０时起泡最为激烈。按碱度不同，泡沫渣的体积在一定的脉石含量及温度范围内出现一个最大值。加入１．０％～３．５％Ｋ_２Ｏ可明显强化酸性和自熔性渣的起泡行为。更多还原

【Abstract】 Using a photoelectric measurement method, the foaming behavior of sinter from a dissected blast furnace was investigated. The influences of various factors on the foaming were further studied on synthetic specimens.The foaming capacity of sinter decreases with the increase of its reduction degree which has been achieved in the blast furnace, The melt with a basicity of 0.7 to 1.0 foams more intensively than the ultra-acidic and the highly basic ones. The volume of foam exhibits a maximum within a certain range of the gangue content and the temperature,depending on the basicity of melt. An addition of 1.0%～3.5%K₂Ocan intensify the foaming process of acidic and self-fluxing melts.更多还原
