I use to work in a steel mill as an electrician. So I snapped a few photo's while worked there. I thought they were pretty cool, so here is one of them. This is electric arc furnace used to melt steel scrap. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750F). Steel often melts at around 1370 degrees C (2500F).
