Study on Anode Baking Parameters in Open-Top and Closed-Type Ring Furnaces

Anode quality has strong impacts on the net carbon consumption in electrolysis cell and subsequently on aluminum production costs. Moreover, inasmuch as baking process is the most expensive step in the anode production and in the other side, anode properties influenced by baking process, therefore furnace selection (open-top or closed-type) and baking process control are always prime priorities that have to be deliberately taken into accounts by smelters. Furthermore, the most important baking parameters are the anode heat-up rate and the baking level, in that the present study deals with the main factors such as influence of firing section on temperature gradient as well as the effect of heat-up duration and anode size on baking level.
