  ABSTRACT: The weakly caking Australian Agro-Allied coal sample mixed with 7% un-reactive coke breeze was subjected to stamped charging prior to carbonization for 22 hours in a 250kg pilot plant to improve the resulting coke strength. The coal was carbonized with a bulk density of 1,000kg/m3 and heating flue temperature of 1,340℃. The screen distribution analysis and the micum tests conducted on the coke gave M10 and M40 of 15.90% and 73.20%, respectively. These results show that the Agro-Allied coke produced is inferior to the coke from a normal top charged counterpart with M10 and M40 indices of 15.40% and 78.20%, respectively and do not satisfy the requirements for the blast furnace ironmaking process. These results thus suggest that the stamped charging coking improvement method designed for high caking, high volatile coals may not be able to improve the strength of coke resulting from a weakly caking, medium volatile coal mixed with coke breeze.
