分析了锌和碱金属等有害元素在炉内行为和攀钢高炉结瘤物成分及有害元素走向，揭示了有害元素对攀钢钒钛磁铁矿高炉冶炼产生的危害，锌对攀钢高炉已经产生危害，而碱金属目前未对高炉产生不良影响，但随着炉料结构的变化不容忽视，并提出了相应的应对措施。
The behavior and distribution in products and byproducts of detrimental elements, such as zinc and alkali metals in blast furnaces were studied. The compositions of accretions in blast furnaces were analyzed. The results show that detrimental elements is bad to blast furnaces. The damages of zinc to blast furnaces were found. With the changes in the structure of burden, the effects of alkali metals on blast furnaces, which had not adverse impacts on blast furnaces until now, could not be ignored, and the corresponding measures were put forward.
