摘　　要：目前国丰钢铁公司高炉冶炼状况下降、冶炼条件变差,通过对国丰2、5号高炉碱负荷计算和碱金属循环富集特点的研究,分析了碱金属在高炉冶炼中的循环富集行为和碱金属对炉料性能以及高炉冶炼的影响。国丰2、5号高炉碱负荷为8.102 kg/t,碱负荷较高是影响国丰高炉顺行的主要原因,提出了在现有操作条件下高炉内碱金属的潜在危害及有效防治措施。The smelting conditions of BF in Guofeng Steel are worse. Through the calculation of enrichment and load of the alkali metals in No. 2 and No. 5 BF in Guofeng Steel, the behavior of circulation and enrichment of alkali metals in BF and the effect of alkali metals on burden and BF process are analyzed. The load of the alkali metals was 8. 102 kg/t. Leading cause of influencing BF smooth running is high load of alkali metals. Potential harm of alkali metals and effective countermeasure were put forward.
