| Abstract Scope |
Carbon anodes used in aluminum smelting are made from a hot mixed paste of aggregate and coal tar pitch binder. Paste is then formed into green anodes, most commonly by vibrocompaction at about 150°C. After forming, hot green anodes are cooled using methods such as air, water bath or water spray, or a combination of these media. Cooling enables the anode to retain shape after forming and be mechanically handled without damage. After cooling, green anodes are baked by heating to ~1100 °C over ~6 days. During water bath immersion or spray cooling, anodes absorb a significant amount of water. The vaporization of this water during baking may affect fuel efficiency, and/or damage the anode structure. Anode reactivity may also be modified by the reaction between water and carbon. During this initial study, the effect of water absorbed during green anode cooling on aspects of laboratory baked anode quality was investigated. |
