摘　　要：针对超高温电弧炉腔内温度场分布及热量传导规律难以准确表征的问题,借助傅立叶热传导定律和牛顿冷却定律,结合COMSOL仿真试验,对冶炼炉腔内电弧各部分热量的产生过程、热量分布、热量传导及流动规律进行深入分析。以铍铜合金冶炼过程为例,计算了沿石墨电极轴向热传导量和沿横向热传导量。结果表明:电弧炉口火焰温度可反映炉腔内电弧近极段温度,通过炉口火焰参数检测可计算得到炉腔内近极段温度;冶炼炉腔内热量的流动方式服从轴向热导和横向热导两个关键过程,通过降低轴向热导的热量耗散和提高横向热量占比,能够提高电弧炉能源有效利用率。To address the problem that it is difficult to accurately characterize the temperature field distribution and heat conduction law in the ultra-high temperature arc furnace cavity,the heat generation process,heat distribution,heat conduction and flow law of each part of the arc in the smelting furnace cavity are analyzed in depth with the help of Fourier's Law of Heat Conduction and Newton's Law of Cooling combined with COMSOL simulation experiments.Taking the beryllium-copper alloy smelting process as an example,the axial heat conduction along the graphite electrode and the lateral heat conduction were calculated.The results show that the flame temperature at the mouth of the electric arc furnace can reflect the temperature of the near-pole section of the arc in the furnace chamber,and the temperature of the near-pole section in the furnace chamber can be calculated by the flame parameter detection at the mouth of the furnace.
