How steel is made
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." Blast furnaces require many auxiliary facilities to support their operations.

How Does an Electric ARC Furnace Work? | Hunker
Invented in France in 1907, these furnaces are a crucial part of iron and steel recycling operations. They're featured in "minimills" that recycle iron scrap for reuse. Arc furnaces are also used in the production of steel. The design of these furnaces makes them simple enough to be built at home by hobbyists, as well.
