| 摘 要： | 结合蓄热式铝熔炼炉熔炼过程的特点，运用FLUENTUDF和FLUENTScheme混合编程，耦合用户自定义熔化模型和燃烧器换向及燃烧量变化模型，实现了蓄热式铝熔炼炉熔炼过程的数值模拟。依据优化原则，获得了熔炼时间随影响因子的变化规律：熔炼时间随着旋流数、燃烧器倾角、空气预热温度或天然气流量的增加而缩短；熔炼时间随着燃烧器间水平夹角或空燃比的延长，先减小而后增加：熔炼时间随着燃烧器高度的增加而延长。 |

| Abstract: | According to the features of melting process of regenerative aluminum melting furnaces, a three-dimensional mathematical model with user-developed melting model, burner reversing and burning capacity model was established. The numerical simulation of melting process of a regenerative aluminum melting furnace was presented using hybrid programming method of FLUENT UDF and FLUENT scheme based on the heat balance test. Burner effects on melting process of aluminum melting furnaces were investigated by taking optimization regulations into account. The change rules of melting time on influence factors are achieved. Melting time decreases with swirl number, vertical angle of burner, air preheated temperature or natural gas flow; melting time firstly decreases with horizontal angle between burners or air-fuel ratio, then increases; melting time increases with the height of burner. |
| Keywords: | regenerative aluminum melting furnace burner melting process numerical simulation multi-element non-linear regression |
