How Does an Electric ARC Furnace Work Hunker

How Does an Electric ARC Furnace Work Hunker

Arc furnaces melt down scrap and ore through the use of their graphite electrodes. When power is fed into the furnace, the electricity jumps between the two energized electrodes and into the neutral, grounded electrode. The high-voltage electric arcs created by these graphite spikes give off large amounts of direct and radiant heat that melt ...

The 50% and 75% ferrosilicon (FeSi50 and FeSi75) alloys are produced by carbothermic reduction in a submerged arc furnace. The source of iron is either iron ores or scrap and that for silicon is quartz or quartzite. The principal smelting reaction is the same as that for smelting of metallurgical grade silicon metal (Schei et al. 1998).
