摘　　要：为了更好地利用各种烧结熔剂,使用"座滴法"研究了6种烧结熔剂的同化行为。结果表明,活性度高的生石灰比活性度低的生石灰同化行为好;活性度相同的生石灰MgO质量分数低的同化行为好;石灰石与Fe_2O_3纯试剂反应的同化行为较好,这主要是由于高温下生成了高活性的CaO;白云石的同化行为较差,这主要是由于白云石中的MgO形成了MgO·Fe_2O_3高熔点物质。6种烧结熔剂的同化行为中生石灰A的同化行为好于生石灰B,生石灰B、石灰石A和石灰石B的同化行为非常接近,生石灰B的同化行为好于生石灰C,白云石的同化行为最差。In order to make better use of all kinds of sinter fluxes,the assimilation behavior of six sinter fluxes was studied by the seat drop method.The results displayed that the assimilation behavior of the high activity quicklime was better than the low activity quicklime.The assimilation behavior of the low MgO quicklime is better.The assimilation behavior of limestone is better,which is mainly due to the formation of highly active CaO at high temperature.The assimilation behavior of dolomite is poor,which is mainly due to the formation of MgO·Fe2O3.The assimilation behavior of quicklime A is better than that of quicklime B,the assimilation behavior of quicklime B,limestone A and limestone B is very close.The assimilation behavior of quicklime B is better than that of quicklime C,the assimilation behavior of dolomite is the worst.
