摘　　要：解析电解槽内衬热耗散机理对于电解槽设计十分重要,关键考虑电解槽两个区域的热损失,第一区域是槽温与槽周空气温度所形成的温度梯度产生的驱动力,另一个区域主要的驱动力是槽子的过热度。文中着重分析了电解槽熔体区的散热现象。It is important to well understand the physic of the heat dissipation inside the lining of an aluminum reduction cell for designing a new cell. The key feature to take into consideration is the 2 zones heat loss mechanism. In one zone, the driving force is the global thermal gradient between the cell operating temperature and the cell ambient temperature. While in the other zone, the driving force is the cell superheat. In this paper some phenomenon of the heat dissipation in the molten zone has been analyzed.
