The present invention relates to a manufacturing process for an anode assembly intended for cells for the production of aluminum by electrolysis, the anode assembly being of the type having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member, the method comprising a formation phase of at least one sealed area filled with sealing material and at least one unsealed area devoid of sealing material, said at least one unsealed area extending to one of the longitudinal ends of the longitudinal member.
A method of manufacturing an anode assembly intended for cells for production of aluminum by electrolysis, the anode assembly having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member for sealing the longitudinal member to the carbon anode, the longitudinal member having longitudinal ends, characterized in that the method comprises a formation phase comprising forming at least one sealed area within a gap between internal walls of the cavity of the carbon anode and the longitudinal member filled with sealing material and at least one unsealed area within the gap devoid of sealing material, the at least one unsealed area extending directly from and in contact with one of the longitudinal ends of the longitudinal member, wherein the formation phase includes fitting a shuttering material into the gap so as to define at least one sealing area and at least one non-sealing area, and filling the sealing area by casting of the sealing material in liquid or viscous state.
An anode assembly intended for cells for production of aluminum by electrolysis, the anode assembly having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member for sealing the longitudinal member to the carbon anode, the longitudinal member having longitudinal ends, characterized in that the anode assembly further comprises a gap between the cavity and the longitudinal member, the gap including at least one sealed area containing a sealing material and at least one unsealed area devoid of sealing material, the at least one unsealed area extending directly from and in contact with one of the longitudinal ends of the longitudinal member.
An anode assembly intended for cells for production of aluminum by electrolysis, the anode assembly having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member for sealing the longitudinal member to the carbon anode, the longitudinal member having first and second opposed longitudinal ends, characterized in that the anode assembly further comprises a gap between the cavity and the longitudinal member, the gap including at least one sealed area containing a sealing material and a first unsealed area devoid of sealing material, the first unsealed area extending directly from and in contact with the first longitudinal end of the longitudinal member.
