Metal Profile: Iron Properties and Characteristics

Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production. Pig iron still contains between 3.5-4.5% carbon, along with other impurities, and is brittle and difficult to work with.
