MIREA: An on-line quality control equipment integration in an operational context

Abstract

Electrical resistivity is one of the key performance parameters of prebaked anodes. Nowadays, the desire to lower anodic incidents and energy consumption can be attained with a state-of-the-art equipment, which is able to accurately measure the electrical resistance of baked anodes on a production line. Anode/carbon plant improvements will be achieved by a better understanding of the impact of the physical properties of the anode in the cell and the fundamental causes of anode defects. This paper presents an overview of the milestones and challenges of implementing such a device into a mature carbon plant and ensuring acceptance from the production (or operation) team. This innovative device will provide opportunities for smelters to improve their cost- Effectiveness by reducing process variation and maximizing anode performance in the cell.
