摘　　要：分析了国内外常用的几种测定焦炭与CO_2反应性的方法,发现用这些方法测得的反应性指标CRI和反应后强度指标CSR对高炉软融带碳溶反应缺乏模拟性。为此,用特制的大型高温反应炉进行模拟高炉软融带碳溶反应条件实验,得出碱对焦炭的碳溶反应具有正催化作用;随着所加碱的质量分数的增加,焦炭的反应性增大,反应后强度略有降低,反应后焦炭的平均粒径略有减小。This paper introduces several determination methods of CRI of coke reacting with CO2,it was found that the CRI and GSR from these methods can not exaclty express the coke quality for blast furnace. Thereby a new method was put forward, which simulates carbon s solution loss reaction in cohesive zone of blast furnace for three industrial coke samples with the big type reaction stove. Finally, some results were obtained:with the increasing of percent of added alkali, the CRI enhances, the CSR decreases slightly and the average granularity minishes slightly.
