Developments in electric arc furnace steelmaking
2001In recent years, the growth of EAF steelmaking and the corresponding push for improved productivity and lower energy usage, has seen a blurring of the boundary between oxygen and electric steelmaking and a departure from the pure batch processing operating philosophy associated with early EAF steelmaking.

Valorization of electric arc furnace primary steelmaking slags for cement applications
Waste Management, 2015To produce supplementary cementitious materials from electric arc furnace (EAF) slags, FeO was reduced using a two-stage reduction process that included an Al-dross reduction reaction followed by direct carbon reduction. A decrease in FeO was observed on tapping after the first-stage reduction, and further reduction with a stirred carbon rod in the ...

Hydrometallurgical Treatment of Steelmaking Electric Arc Furnace Dusts (EAFD)
Metallurgical and Materials Transactions B, 2013The aim of the current research study was the development of a hydrometallurgical process for the recovery of metals from electric arc furnace dust. The behaviors of zinc, cadmium, iron, and lead in sulfuric acid were investigated. The recovery of the zinc (from zinc oxide) and cadmium is possible with a relatively high yield, as iron and lead remain ...

Modern Steelmaking in Electric Arc Furnaces: History and Development
2013Process, ecological, economic, health, and safety requirements in steelmaking units. The change in these requirements with developing of current steel production. A negative effect of existing contradictory practice is the forming in prices for scrap, iron, electrical energy, and natural gas on general technological progress in steelmaking. Increasе in

Estimation of the states during refining in electric-arc-furnace steelmaking
Proceedings of the Institution of Electrical Engineers, 1977The commercial incentives to obtain improved control of the steelmaking process in the electric-arc furnace are presented, and the progress made in applying computer control is reviewed. The development of a mathematical model of the refining process is shown to be restricted by the complex metallurgical nature of the process and the deficiency of ...

Dangerous Emissions During Steelmaking in Electric Arc Furnaces
2016The steelmaking in the electric arc furnaces (EAFs) is in the category of industrial processes with high degree of pollution. In the air environmental factors are transferred the following dangerous substances: carbon oxides, sulphur dioxide, nitrogen oxides, volatile organic compounds, polychlorinated dibenzodioxins, polychlorinated dibenzofurans and ...
