摘　　要：为了了解六电极电炉在生产过程中电参数和温度场的变化规律,利用ANSYS软件实现炉内物料热电场的数值模拟。通过对六电极电炉电场和温度场的模拟,得到炉内主要发热区和温度分布规律,验证该电炉的可行性与安全性。结果表明:六电极连续式石墨化电炉的主要发热区域集中在相邻电极之间,炉内最高温度达3 093℃;高温区温度分布较为均匀,其温度均在2 360℃以上,可以保证物料的充分石墨化。炉体内壁和电极温度均在安全范围内,六电极连续式石墨化电炉可以实现安全连续生产。In order to understand electric parameters and the change of temperature distribution in the electric furnace production process, finite element theory is combined with ANSYS software to realize numerical simulation. The main heating zone and temperature distributions in the furnace are obtained according to the simulation of electric field and temperature field in the electric furnace, and the feasibility and security of electric furnace is verified. The simulation results show that the main heating area concentrates between the adjacent electrodes in the continuous graphitization electric furnace. The highest temperature is above 3 093 ~C; high-temperature zone is more uniform temperature distribution, and above 2 360 ~C ,which can ensure material fully graphitized. The temperature of inner walls and the electrodes are in the security range. The six-electrode continuous graphitization electric furnace can achieve a continuous production of loose graphite.
