Interaction Study of the Paste Plant Production Parameters on VS Soederberg Anode Paste Fluidity and Baked Anode Performance

摘要

Anode performance during cell operation depends on its intrinsic quality and the cell operation parameters. The intrinsic quality of an anode is strongly influenced by the characteristics of the raw material (coke and pitch) and by the paste production process. A factorial experimental design has been used to establish the interaction between the paste plant production parameters and the paste and baked anode properties. This laboratory study determined the effect of the variability of certain parameters such as binder level, mixing temperature, coke size distribution and coke super fine (-43 μm), on the paste fluidity and the performance of the anodes.
