"Mining Magnetite for your future." - Asia Iron

Pig iron is not pure iron, but has 4-5% carbon dissolved in it with small amounts of other impurities like sulfur, magnesium, phosphorus and manganese. As the carbon is the major impurity, the iron (pig iron) becomes brittle and hard. This form of iron is used to cast articles in foundries such as stoves, pipes, radiators, lamp-posts and rails.

Jan 01, 2021· Ordinary pig iron contains about 4% carbon. When the carbides dissolved in the molten iron reach saturation, the remaining carbides remain in the slag, such as SiC when high-Si pig iron is smelted, and TiC formed when the ore contains TiO 2. The melting temperatures of carbides are generally high (melting point of TiC>3290°C, and SiC>2700°C).
