“…These factors lead to an additional electrical resistance, thus a higher production cost. Finally, the extreme conditions of the process can cause large changes in the geometry of the connection leading to an additional energy loss [4]. It is important to consider that the manufacture, operation, maintenance and cleaning of the assembly represent a significant portion of the aluminum production costs [5].…”

“…This element leads to a premature maintenance of the anode assembly. In 2013, Molenaar et al [4] used a high amperage testing facility to study the impact of deterioration parameters including the change of stub diameter, height and the eccentricity of the stub in the stub hole on anode performance. He concluded that a net increase of more than 50 mV is possible for a deteriorated anode rod fleet.…”

“…During cast iron solidification, the cast iron pulls away from the stub hole, forming a shrinkage gap that affects the contact voltage drop during cell operation, which is relative to temperature history during solidification. It was reported that poor casting process would result in an increase of the anode voltage drop of about 50 mV [1]. Secondly, the cooling rate has great effects on the final phase and microstructure of the cast iron, affecting the performance of the cast iron, such as ultimate tensile strength (UTS), hardness, and elongation [2,3].…”
