高炉能量变化情况的影响因素分析 摘 要 探究大型高炉能量影响因素，有助于提高高炉能量利用率，为大高炉高效、节能、环保的生产提供意见，争取可以达到企业可持续发展的经济目标，提升企业核心竞争力。 本次研究以3200m3高炉生产数据为基础，提取所需的原始数据，分析主要能量因素对3200m3高炉能量变化的影响，利用excel工具及控制变量法，结合物料平衡、热平衡对主要因素进行模拟计算，进而建立了相应能量因素关系图表，分析指标变化后对高炉能量分配的影响，根据本次模拟计算结果分析得出：熟料率在75%-85%范围较好，燃料比“310kg+150kg”为理想值，热风温度保持1200℃上下。得到以下：3200m3高炉保持良好熟料率，保证精料“高”、“稳”，减低燃料比，适当降低焦比，合理喷吹煤粉同时提升热风温度，提高高炉能量使用率，降低炼铁成本。 关键词：高炉 能量 模拟计算 因素分析  ABSTRACT To explore influencing factors of large blast furnace energy, help to improve the utilization rate of blast furnace energy for a big blast furnace production on high efficiency, energy saving, environmental protection, can achieve economic objectives for the sustainable development of enterprises, improve enterprise core competitiveness. The papers from 3200 m3 blast furnace based on production data, extract the original data, the analysis of main factors on the energy changes of 3200 m3 blast furnace energy, using excel tool and the control variable method, combining material balance, heat balance simulation calculation, the main factors to establish the corresponding energy factor relationship diagrams, analysis indicators after changes impact on the energy distribution of blast furnace, according to the results of the simulation analysis: better clinker rate from 75% to 85% range, fuel ratio 310 kg and 150 kg as the ideal value, hot blast temperature 1200 ℃. Get the following conclusions and recommendations: 3200 m3 blast furnace to keep good rate of clinker, ensure concentrate high, stability, reduce fuel ratio, appropriate to reduce the coke rate, reasonable coal injection while increasing hot blast temperature, improving energy utilization rate, blast furnace ironmaking cost.
