铝电解的经济技术指标不仅与电解生产有直接关系,与铸造方法和铸损率也有很大关系。本文通过对原铝连续铸造和铸损的分析,揭示了降低铸损,提高经济效益的途径。目前国内大部分电解铝厂是将电解原铝液经过混合保持炉进入铸造机铸造生产成重熔用铝锭,为了能够有效降低铸损率一般均采取连续铸造方式进行生产。连续浇铸可分为混合炉浇铸和外铸两种方式,均使用连续铸造机。混合炉浇铸 Economic and technical indicators of aluminum electrolysis is not only directly related to electrolytic production, and casting methods and casting loss rate also has a great relationship. In this paper, through the analysis of continuous casting and casting loss of primary aluminum, the ways to reduce cast loss and improve economic efficiency are revealed. At present, most electrolytic aluminum smelters in China use the electrolytic primary aluminum liquid to enter the casting machine for casting to produce the remelting aluminum ingot through the mixing and holding furnace. In order to reduce the casting loss effectively, the continuous casting method is generally adopted. Continuous casting can be divided into two kinds of mixing furnace casting and casting, are used continuous casting machine. Mixing furnace casting
