“…Hulse [4] reported that the temperature, the pitch content, and the coke particle parameters such as size distribution, shape, roughness, and tendency to agglomerate, affects the granulo-viscoelastic behaviour of the anode paste. Gildebrandt et al, [7,8] Kravtsova et al, [9] and Vershinina et al [10] studied how the temperature, the fine coke particle size, and the content affect the viscosity of the binder matrix. The viscosity was found to decrease with both increasing the temperature and the particle size.…”

Effect of fine coke particles on rheological properties of the binder matrix of carbon anodes in aluminium production process

Aluminium production through the Hall-Héroult process relies on an extensive use of carbon anodes, which are originally made of coal tar pitch and fine and coarse carbon particles. During the forming process of green anodes, the mixture of the fine particles and the coal-tar pitch (i.e., the binder matrix) moves between the coarse particles and produces a uniform agglomerated paste. The efficiency of the forming process directly affects the final quality of the baked anode and consequently the efficiency of the Hall-Héroult process. The rheological properties of the binder matrix play a crucial role in the forming process. In this study, rotation and oscillation tests are used to study the effects of the fine particle concentration and temperature on the viscoelastic properties of the binder matrix. The
