摘要: Abstract Constructal theory is introduced into the hot metal yield maximization of blast furnace in this paper. Generalized constructal optimization a performed for specified total raw material cost. The optimal distribution each cost cost, namely “generalized construct”, obtained. Besides, charge composition also effects parameters, agglomerate ratio and pulverized coal dosage on results are analyzed. show that after generalized 1027.4 kg, improved by 2.64% compared with before optimization. For actual production furnace, when fixed, decreasing oxygen enrichment, volume, increasing can increase yield. Increasing humidity always under certain value. contribution paper to optimize based new methodology, which leads good economic performance iron-making process provides guidelines design process.
