摘要
以首钢现场高炉渣为基础渣样,采用三角锥试样变形法,在高Al2O3含量的条件下研究了炉渣二元碱度、Al2O3含量及MgO含量对高炉渣熔化性能的影响.结果表明：三角锥试样变形法可以使炉渣试样的熔化变形过程更明显,特征温度的判断也更加准确;炉渣二元碱度（1.0～1.25）以及Al2O3含量（15％ ～ 22％）增加均会使炉渣熔化性温度出现较为明显的升高;适当地增加MgO含量可以在一定程度上改善炉渣的熔化性能.
With site blast furnace slag of Capital Steel as basic slag sample, and triangular pyramidal specimen deformation method, It is researched the influence of slag binary basicity, Al2 O3 content and MgO content on the melting property of blast furnace slag. It is showed from the result that triangular pyramidal specimen de- formation method can cause melting deformation procedure of slag sample more obvious, judgment of charac- teristic temperature more accurate; the slag melting temperature would be obvious higher along with the slag binary basicity （ 1.0 - 1.25） and Al2O3 content （ 15% - 22% ） increased; the melting property of slag can be improved to a certain extent with MgO content appropriately increased.
