摘　　要：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。The influence factors and judgment methods of blasting kinetic energy for Anshan Steel＇s No. 2 3 200 m^3 BF are analyzed briefly, and the rational scope and control procedures of blasting kinetic energy for No. 2 BF are discussed by means of statistically analyzing the BF＇s production data. The results show that realization of low fuel rate and high production of BF depends on rational blasting kinetic energy, which can be achieved through properly controlling the blast flow, blast ratio, tuyere area and oxygen enrichment rate, in addition to upgrading the condition of raw material and fuel. For Anshan Steel＇s No. 2 3 200 m^3 BF, the rational blasting kinetic energy ranges from110 to 130 k J/s, and the reasonable blast ratio ranges from 1.75 to 1.80, while the reasonable raceway length is about 1.82 m.
