The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!

Coal is used as the main carbon-bearing material for steel making. It also serves to generate the high temperatures necessary to smelt the iron ore. Liquid iron is about 1,500 degrees hot when it leaves the furnace. Since iron is brittle and not easily formable it has to be turned into steel in a second step.
