摘　　要：实验表明，高炉高富氧喷煤条件下，沪内的温度分布、矿焦比、煤气成分与流量对焦炭的溶损量和热强度影响显著。煤气中ＣＯ或Ｈ＿２含量增加，会提高焦炭的溶损率和粉化程度；反应温度和矿焦比升高也有相同的结果。AbstractAccording to the experiments, it shows that the reaction temperature, ratio of ore to coke(O/C),gas composition and velocity have an influence on the coke solution loss and strength in BF with high oxygen enrichment and coal injection. A high CO or H_2 content of the gas will inc-rease the rate of coke solution loss and degradation. The raise of temperature or O/C can bring about the same effect.
