EFFECTS OF PHYSICAL PROPERTIES OF ANODE RAW MATERIALS ON THE PASTE COMPACTION BEHAVIOR

摘要

The current study investigates the effects of coke particlecharacteristics and paste formulation on the flowability and thecompression behavior of anode pastes. Shape factor and texture ofdifferent fractions of cokes were characterized using an imageanalysis system where the characteristics of each coke werecorrelated to its vibrated bulk density (VBD). A compression testwas designed to study the effects of particle characteristics andpaste recipe on the compactability of pastes. The test was appliedon four anode pastes, prepared from different coke types, particlesize distributions and pitch contents. It was observed that thecompression test is significantly sensitive to any changes in rawmaterials characteristics and formulations. Consequently, thecompression test may be used as a tool for evaluating anodequality in relation with material variations.
