摘　　要：为提升铝熔炼炉热效率、降低污染物排放和提高熔体质量,在对某厂蓄热式铝熔炼炉热平衡测试的基础上,建立合理的铝熔炼炉模型,提出了优化准则。运用计算流体力学软件Fluent对铝熔炼炉燃烧器不同水平夹角下铝液和炉膛的耦合物理场进行了仿真优化。经过对不同燃烧器水平夹角下的优化分析,结果表明,燃烧器水平夹角为90°时,铝熔炼炉能获得最佳的熔炼性能。In order to improve the energy efficiency and melt quality and to reduce the pollutant emission,based on validating results by heat balance test for regenerative aluminum melting furnace from a company,a reasonable model of aluminum melting furnace was established to optimize processing parameters.CFD software Fluent was used to simulate and optimize coupling field between liquid aluminum and combustion space at the varied horizontal angle between burners of the aluminum melting furnace.The results show that the desirable melting performance can be obtained with the horizontal angle between burners of 90°.
