Electric Arc Furnace: Most Efficient Technologies for ...

2019-7-19  In the electric arc furnace, steel is produced only through scrap fusion. Scraps, direct reduced iron, pig iron, and additives are melted through high-power electric arcs formed between a cathode and the anodes. The emissions levels are normally mainly related to the indirect emissions due to the high energy consumption of the process.

The steelmaking industry in semi-integrated plants produces steel from ferrous scrap, using electric arc furnaces (EAF). Besides steel, this operation generates several solid wastes or by-products with low value. Among these wastes, there are some with high iron content, mainly composed of iron oxides, e.g mill scale and EAF dust, which increase the interest on recycling

Recycling - Industrial Scrap Metals Recycling Durban

The scrap is then recycled in an electric arc furnace or a basic oxygen furnace. Recycling scrap protects the environment by: – Reducing the use of raw material. – Reducing the impact of landfill on the environment. – Reduced air pollution. – Reduction in energy as less energy is required to use recovered material to produce steel.
