摘要
首次提出了铝电解槽经济寿命的概念,指出近年在电解铝利润接近零的情况下,一个正常的铝电解系列停槽原因大多取决于其经济寿命,并且给出了经济寿命的简便判断依据和实例。同时,给出了近年大型预焙铝电解槽系列寿命统计分布规律的计算方法,可为生产管理者决策提供依据,以及能够从具体生产操作和宏观方面为铝电解槽的大修提供科学的决策依据,最大限度保护企业投资。
In this paper the concept of economic life time of aluminium electrolytic cell is expressly issued for the first time. It＇s pointed out that, under the condition of almost zero profit in aluminium electrolysis industry in recent years, the reason of stop over of a normal electrolysis series is primary dependent on its economic life time; and a lot of simple judgement basis of economic life and examples are provided. Furthermore, the calculation methods of statistical life distribution trend of large-type pre-baked aluminum electrolytic cell series are introduced. Its can be regarded as the decision-make basis for production management. In adition, It＇ s expected to provide scientific decision-make basis of electrolytic cell large-repairing in view of both protect the investment of enterprise extremly. actual production operation and macro aspects. So as to
