iron ore to cast iron process

Cast irons - University of Cambridge

Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as cementite.

Iron Bloomery - The most basic process used from the iron-age to medieval times. Charcoal, iron ore and air are combined to smelt an iron "bloom". The iron bloom is forged and worked to the final "Wrought Iron" shape. During the iron-age, bloomery furnaces rapidly replaced open charcoal fires as an effective way to forge.
