云南某钢企炼铁资源有害元素初步平衡研究(上篇)

Study on Primary Balance of Harmful Elements in Ironmaking Resources of one Yunnan Steel-making Enterprise(Part One)

原燃料带入的有害元素进入高炉后会对产品质量和指标产生诸多不利影响。针对某钢企高炉的入炉硫、钾钠及锌等有害元素进行了初步平衡研究,对硫元素的全面分析结果表明,现代高炉具有很高的脱硫效率,影响烟气硫超标的关键是控制入炉硫负荷<3.0 kg/t Fe。

The harmful elements in crude fuel have many negative impact on product quality and production indicators when the crude fuel fed into blast furnace.The quantitative analysis research method was adopted for the primary balance study on sulfur,potassium,sodium,zinc and the other harmful elements fed into blast furnace of one steel enterprise.The comprehensive analysis results of sulfur element show,the modern blast furnace has very high desulfuration efficiency,controlling of sulfur load of the furnace<3.0 kg/t Fe is the critical factor for influence of excess sulfur in fume.
