Abstract
The purpose of this work is to review modern foreign experience to investigate cast iron used in the installation of anodes for aluminum electrolysis production at JSC «Kazakhstan Aluminium Smelter». In the course of the study, the chemical composition of cast iron was analyzed and the selection of experimental cast iron compositions was carried out. The research revealed that one of the causes of the problem of incomplete removal of cast iron from steel nipples of anode holders after the dismantling of cinders and high voltage drop in the contact nipple – anode is the chemical composition of cast iron. The requirements for cast iron for casting anodes have been determined. It is established that to achieve positive results it is recommended to use cast iron of stable composition with low crystallization shrinkage and low phosphorus content; increased fluidity
