受高温真空加热工艺的制约,传统金属镁还原炉内的流动和温度分布极不均匀,排烟温度很高,炉子热效率低。本文模拟计算了新设计开发的蓄热式金属镁还原炉的热过程。通过对炉内流场和温度场的数值模拟,证明该新型还原炉在流场组织、温度场均匀性以及强化金属镁的还原过程等方面具有明显的优势。
Restricted by the high-temperature vacuum heating process, the flow and temperature distribution in the traditional magnesium reduction furnace is extremely uneven, the exhaust gas temperature is high, and the thermal efficiency of the furnace is low. This paper simulates the thermal process of newly designed regenerative metal magnesium reduction furnace. Through the numerical simulation of the flow field and temperature field in the furnace, it is proved that the new reduction furnace has obvious advantages in flow field organization, uniformity of temperature field and reduction of metal magnesium.
