   Will a new electric arc furnace replace a blast furnace?

   • Several of Europe’s biggest steel groups, including ArcelorMittal, Thyssenkrupp and Tata Steel, have announced plans to shift from blast furnaces to new electric arc furnaces. However, much will depend on securing taxpayer support, ensuring promises are kept to develop the necessary infrastructure — such as electrolysers to produce hydrogen.

   Can EAF reduce emissions compared to a blast furnace?

   • Because they use electricity to melt the scrap, making steel using an EAF can reduce emissions by 75-80 per cent compared with a blast furnace. But there are notable challenges. Global scrap supplies are limited and cannot always produce the quality of steel required for certain applications, such as cars.

   How does an electric arc furnace work?

   • An electric arc furnace melts down scrap or recycled steel rather than converting raw materials, notably iron ore, as in a blast furnace. This method can take up to 100 per cent scrap. The electric arc furnace works by generating a high-temperature electric arc between graphite electrodes, using electricity as the energy source.

   Are electric arc furnaces coming online?

   • More and more electric arc furnaces are coming online. Last year, 43 per cent of planned new steelmaking capacity was based on EAF technology, while 57 per cent were still to be coal-based furnaces, according to Global Energy Monitor. This was progress compared with a year before that, when only 33 per cent of planned capacity was set to use EAF.

   6 hours ago · The increase in oxygen content will have an adverse effect on the performance of steel. Therefore, steel has strict requirements on oxygen content, generally not exceeding 0.02%, or even more stringent. Therefore, excess oxygen should be removed during the steelmaking process. Manganese metal ingots have a high manganese content.
