ANODE ASSEMBLY

摘要

An anode assembly (20) for conducting electrical energy to an electrolytic smelting cell comprising an anode (C) of high electrically conductive material connected to a yoke (21), the ends of the yoke (21) being receivable within anodes, said yoke comprising a core (29) of highly electrically conductive material and an outer structural sheath (30) extending substantially the length of the yoke, the anode rod being in electrical contact with the core of the yoke (21) and provided with a protective structural collar secured to the outer structural sheath of the yoke (21). In order for the electrical and thermal contact between the core (29) and sheath (30) to be maintained, the differential co-efficient of thermal expansion over the operating temperature range of the assembly is preferably substantially the same or within 4 x 10<-6> m/mk.
