Abstract
The anode with under-calcined cokes have better component homogeneity and smaller carbon consumption in aluminum electrolysis. In this study, three types of petroleum cokes were calcined at 800, 900, 1000 and 1100 °C, respectively. The content of S and volatiles of cokes were measured against the calcining temperature. The air/CO2 reactivity, electrical conductivity, density, porosity, compressive/shear strength of the bench-scale anode sample made by these cokes were optimized as a function of calcining temperatures. In addition, the LC value and real density of cokes were tested to show calcining level of the cokes. Based on the results above, the optimum calcining level of cokes for the prebaked anodes was obtained.
