| Abstract Scope |
Anode baking level, measured through the crystallite size (Lc) or real density (RD) of baked anodes, is a crucial indicator of the performance of prebaked anodes used in modern electrolysis cells. It significantly affects electrical and mechanical properties and serves as a predictor of the dusting propensity or "wasteful" consumption of carbon anodes. Historically, an Lc value of 29Å was sufficient. However, due to increased variation in raw materials, more stringent electrolysis cell operating conditions, and tighter environmental regulations, it is necessary to strike a balance between the optimal baking level, the lowest practicable carbon consumption, and optimal furnace productivity.
This article outlines the approach taken by Emirates Global Aluminium (EGA) to determine the target baking level to minimize carbon consumption; and the strategy employed to sustain a consistent level of anode baking during the natural age-related deterioration of the bake furnace |
