An integrated mill is capable of the entire steel production process, from the melting of raw materials all the way through processing a finished coil. Regarded as the traditional, purest way of making steel, integrated mills utilize a Basic Oxygen Furnace (BOF) to melt iron ore, coke, limestone, and scrap into molten steel.
