Modern steel furnaces use plasma arcs to reach temperatures twice as hot as a volcano
Modern electric arc furnaces utilize powerful plasma arcs to reach 3,000°C, a temperature twice as hot as volcanic lava, allowing for the efficient recycling of millions of tons of scrap steel annually.
Electric arc furnaces are engineering marvels that use graphite electrodes to create plasma arcs reaching a staggering 3,000 degrees Celsius. This is double the temperature of a typical blast furnace and far exceeds the heat of most volcanic eruptions. By consuming roughly 670 kilowatt-hours per ton of steel, these systems can melt 100 tons of scrap in a single session, requiring as much power as 100,000 households.
