The output of domestic arc furnace steel increased year by year which was near to 50 million ton in 2007. The number of large electric arc furnace increased obviously
in 2007 the output of ≥ 50 t electric arc furnaces was about 83.5% of total electric arc steel
electric consumption decreased near to 300 kWh/t with tap-to-tap time ≤ 60 min and average electrode consumption 2.43 kg/t
but the processes related to charging
steel grade
energy saving and environmental protection need to be promoted. The domestic electric arc steelmaking process is forging ahead.
