Researches Regarding the Air Pollution with Sulfur Dioxide (SO₂) to the Steelmaking

Abstract:

The paper presents the experimental researches regarding the air pollution with sulfur dioxide (SO₂) to the steelmaking in the electric arc furnace. It presents a method for determining the sulfur dioxide (SO₂) concentrations from the steelmaking, the diagram variation of the sulfur dioxide (SO₂) concentrations over time during specific technological stages of the steelmaking process and the potential sources that generate the sulfur dioxide (SO₂) to steelmaking process in the electric arc furnaces. The air pollution during steelmaking in electric arc furnaces is manifested throughout this process, which includes the following technological stages: furnace charging, charge melting, refining, dephosphorization, desulphurization, deoxidizing, alloying and evacuation. Considering the stages of steelmaking in the electric arc furnace that have the potential to generate sulfur dioxide (SO₂), it was assessed its generation evolution for the following technological stages: melting, refining, desulphurization and deoxidizing. The experimental researches were performed on two electric arc furnaces with a capacity of 10 and 30 tons. The highest concentrations of sulfur dioxide (SO₂) were recorded during the desulfurization technological stage. After this stage, it has been recorded a significant reduction in sulfur dioxide (SO₂) concentrations. The sulfur dioxide (SO₂) concentrations from the electric arc furnace with the capacity of 30 tons are higher than those recorded in the furnace of 10 tons with 30-40%.
