Baking Furnace. High quality baked carbon anodes contribute to the optimal performance of aluminum reduction cells. Anodes weighing about 10 kg were produced at the carbon laboratory of UQAC. (7) RESULTS Anode temperature gradient Pitch devolatilization occurs in the anode temperature range between 200 and 600 oc. 04%, Fe content below 0. The anode blocks are then generally baked in pits of ring type furnace in the range of 1100 °C - 1200 °C [2]. This paper will present the current Industry 4. its new ‘in house’ anode baking furnace firing system in 2011. anode reactivity; increasing the anode reactivity increases carbon dust generation which leads to anodes spikes formation. Carbon consumption in pre-bake anode cells is 400–450 kg C/t Al, considerably higher than the theoretical consumption of 334 kg C/t Al. The air permeability of a baked anode is measured by determining the resistance to the airflow through a sample. NKM Noell supplies individual equipment for handling of green and baked anodes as well as complete systems, which may include the following equipment: Anode Stacking Cranes Anode Conveyors Slot Cutting. 7 GJ/t (baked anodes) Pitch burn combustion efficiency up to 99. At the beginning of 2006, it joined Chalco and became a wholly-owned subsidiary of Chalco. Impec anode inspection system is designed to capture images and make an analyse of the baked anode.
