Abstract
Off-gas measurements were performed at two EAFs (electric arc furnaces) of ThyssenKrupp Nirosta in order to set-up precise mass and energy balances. Results show that, with similar production parameters as steel type, scrap an slag former input, coal addition, cooling system, tap-to-tap times, the use of fuel burners and dedusting system operation drastically affects the measured off-gas composition and amount of air infiltration into the furnace vessel. A high degree of air infiltration may result in decreasing the chemical energy load (H2 and CO content) but increasing the total off-gas enthalpy. On the other hand, without additional oxygen input for post-combustion, H2 and CO off-gas concentrations may achieve considerable values. Mass and energy balances for austenitic heats are presented for two TKN steel mills at Bochum and Krefeld.
