Abstract in another language
In highly competitive steel markets worldwide, an economical and climate-friendly steelmaking process is required to ensure profitable crude steel production in future. Considering the tightening global CO2 emission requirements,
which result in rising energy prices and purchasing of CO2 emission certificates, raw material and energy efficiency has to be optimized continuously. One option for increasing resource efficiency in the primary steelmaking process chain is the usage of bottom inert gas purging in the EAF for melting and refining of scrap, direct reduced iron, hot metal, and alloys. Gas purging increases mass and energy transfer in the molten metal, the mixing energy and the bath kinetics, promoting improved reaction capacities for decarburization and dephosphorization. Higher thermal and chemical homogeneity of the liquid metal bath, better process control and increased yield of raw materials by reduction of agent, alloy and oxygen consumptions are essential benefits as well.
