简要分析了高炉鼓风动能的影响因素及判定方法,基于鞍钢2号3200m~3高炉生产数据的统计分析,重点探讨了2号高炉合理鼓风动能的范围和鼓风动能的控制方法。分析结果表明:高炉要取得低燃料比和高产量的效果决定于合理的鼓风动能,可以通过控制合理的人炉风量和送风比、控制合理的风口面积、调整富氧率,以及提高原燃料条件来获得合理的鼓风动能。针对鞍钢2号3200m~3高炉而言,合理的鼓风动能范围为110~130kJ/s,合理的送风比范围为1.75~1.80,合理的风口回旋区长度应在1.82m左右。
Based on the statistical analysis of Anshan Iron and Steel Company No. 2 3200m ~ 3 blast furnace production data, the reasonable blasting kinetic energy range and blasting kinetic energy of No.2 blast furnace are discussed emphatically. The results show that the blast furnace to achieve low fuel ratio and high output depends on the reasonable blasting kinetic energy, which can be controlled by controlling the reasonable furnace air volume and air supply ratio, controlling the reasonable tuyere area, adjusting the oxygen enrichment rate, Fuel conditions to obtain reasonable blast kinetic energy. For Anshan Iron and Steel 2 3200m ~ 3 blast furnace, reasonable blast kinetic energy range of 110 ~ 130kJ / s, a reasonable air supply ratio range of 1.75 ~ 1.80, a reasonable tuyere raceway length should be 1.82m or so.
