找出系统用能的薄弱环节和造成低效率的原因,会对炼铜工业的发展造成深远的影响。本文针对富氧底吹铜熔池熔炼炉的结构特征,从热力学角度出发,依据富氧底吹铜熔池熔炼炉的冶金计算模型,结合实际的生产数据,选择富氧率、铜锍温度、烟气温度、炉渣温度、精矿种类为影响因素,基于均匀设计法,对影响富氧底吹铜熔池熔炼炉生产过程?效率的主要工艺参数进行回归分析,结果表明:在保证炉料间化学反应充分完全的条件下,富氧率和炉渣温度之间存在明显交互作用,随着富氧率或烟气温度减小,炉渣温度或铜锍温度增加,精矿品位增高,则富氧底吹铜熔池熔炼炉?效率增加,为整个富氧底吹铜熔池熔炼炉熔炼过程的节能降耗提供有利基础,并为智能集成决策提供了重要优化理论基础。

A thermodynamic regression analysis of oxygen bottom-blown copper smelting furnace based on uniform design method

XIt is important to ascertain the cause of low energy efficiency in copper smelting industry. Based on structural features of oxygen bottom-blown copper smelting furnace, a thermodynamic model was developed in conjunction with the uniform design method. Oxygen-enriched rate, matte temperature, flue gas temperature, slag temperature and concentrate type were selected as the factors of interest. The uniform design was used to quantitatively investigate these factors. There was obviously synergistic effect between oxygen-enriched rate and slag temperature. If chemical reaction between different components was complete, exergy efficiency increased with decreasing oxygen-enriched rate and flue gas temperature, increasing slag temperature and matte temperature, and higher grade of copper ore. It might provide a theoretical basis for energy-saving decision and the integrated intelligent process optimization of oxygen bottom-blown copper smelting furnace.
