Abstract:

Graphitic carbon as the anode is the one of the main row material of aluminum production. Aluminum is produced by electrolysis of Alumina powder. Pre-baked Anode technology is used in this process. Anode baking is the final step of Anode production. The effect of packing coke size on gas consumption and baked anode quality in open type furnaces were fully investigated in this thesis. For this purpose the three sizes of packing coke were tested (very coarse, coarse, and medium).Gas consumption and Anode quality parameters were tested and recorded according to ISO standard in each baking cycle by laboratory. The lowest gas consumption is related to medium size packing coke which is 12% lower than the case of usage coarse. The highest gas consumption occurred when very coarse packing coke was used which is 9% more than coarse usage and also the quality of Anode when coarse packing is used has less deviation from standard parameter finally with regards to results of the investigation done the coarse grain size is the optimum size in comparison with others and also to avoid Anode burning, usage of medium size packing coke even fine on top layer of Anode coverage in baking furnace is recommended
