通过对高炉原燃料的K、Na、Zn含量分析,并进行投入支出平衡计算,找出烧结矿、球团等是高炉碱、锌负荷的主要来源,高炉渣是排碱的重要途径,布袋灰和重力灰是排锌的主要途径。探讨了减少高炉内碱、锌富集的方法和措施,控制进厂精粉碱、锌含量,废物料脱碱、脱锌,降低炉渣碱度,减少块状带吸附等,可有效降低高炉的碱害、锌害。 By analyzing the content of K, Na and Zn in the blast furnace fuel and calculating the input balance, it is found that sinter and pellet are the main sources of blast furnace alkali and zinc load. Blast furnace slag is an important way to remove alkali, And gravity ash is the main way of zinc row. The methods and measures to reduce the concentration of alkali and zinc in the blast furnace were discussed, and the control of alkali, zinc content, dealkalization of waste materials, dephosphorization of slag, reduction of basicity of slag, Alkali damage, zinc damage.
