An experimental investigation of the sealing process of an anode assembly used in electrolysis cells has been performed to better define the thermal and mechanical aspects of the cast iron thimble solidification between the steel stub and carbon hole. Three holes of a baked anode have been thoroughly measured with a Coordinate Measuring Machine (CMM) to obtain a high precision three-dimensional map of the carbon interface. These measurements were then compared to the outer surface of the frozen thimbles to obtain a room temperature air gap dimension. Thirty-nine thermocouples, placed in a strategic configuration, allowed the reconstruction of the temperature field in the steel stub, carbon block and solidifying cast iron thimble from the pouring to room temperature. Hence, heat transfer coefficients can be evaluated at the carbon/cast iron and steel/cast iron interfaces with a thermal model. Metallographic analysis is matched with the cooling curves.
