| 摘 要： | 首先通过分析还原罐中心温度变化曲线,提出了在罐内安装导热装置的必要性,然后设计了导热装置的形状,通过试验并进行了改进,验证了传热效果和对镁结晶的影响。通过ANSYS模拟安装导热装置后罐内温度场,计算了中心温度达到反应温度所需要的时间,并和没有安装导热装置的温度场进行比较,从而为缩短了还原时间提供了依据。

| Abstract: | The temperature curve of the point in the central axis of reduction pot is analyzed, the necessity of fixing the conduction device in the pot is brought forward. Then, the mode of the device is designed. It is improved by experiment. Thermal conduction effect and magnesium crystal are verified by experiment. Thermal field of fixed the conduction device is simulated by ANSYS, the time of the center temperature up to the reaction temperature is calculated, which is compared with the thermal field of the unfixed. |
