Micro-properties of Australian Coking Coals

Abstract: The properties of a suite of experimental cokes made from Australian coals were studied. Image analysis was used to quantify the coke pore and pore wall microstructure, while ultra-micro indentation characterised the strength of the coke wall textures. The micro-properties were compared with compact tension measurements of bulk coke strength. The microstructural features of good cokes included a relatively thick coke wall, and a pore size distribution that has small mean pore size combined with a high pore den… Show more

“…It performs several important functions, such as provision of reducing gases, fuel for supporting the necessary temperature, and provides a source of carbon in order for the hot metal to have certain properties [22]. Furthermore, it supports the burden to ensure good permeability for the transmission of reducing gasses and liquid phase drainage.…”

“…Smaller pores are not expected to have significant effect on the mechanical properties of carbonaceous materials. [16] Feret ratio, the shape factor, of all carbonaceous materials varied between 52 and 59 pct. After 2 hours of annealing at 1773 K (1500°C), no significant variation in pore shape was observed.…”
