Pig iron is an intermediate product of the iron industry. Pig iron has a very high carbon content typically 3.5 - 4.5% along with silica and other constituents of dross which makes it very brittle and not useful directly as the material except for limited applications.

Pig iron is made by smelting iron ore into a transportable ingot of impure high carbon content iron in a blast furnace as an ingredient for further processing steps.
The traditional shape of the mould fused for pig iron ingots was a branching structure formed in The sand with many individual ingots at right angles to a central channel or runner resembling a litter of piglets. Being suckled by a cell when the metal had cooled and hardened the smaller ingots.
The pigs were simply broken from the runner the salle hence the name pig iron. As pig iron is intended for remelting the uneven size of the ingots and the inclusion of small amounts of some caused only insignificant problems considering the ease of casting and handling them.
Traditionally pig iron was worked into wrought iron and finery forge later puddling furnaces and more recently into steel in these processes. Pig iron is melted and a strong current of air is directed over it while it is stirred or agitated.
This causes the dissolved impurities such as silicon to be thoroughly oxidized an intermediate product of puddling is known as refined pig iron. Fibers metal or refined iron pig iron can also be used to produce grey iron. Slag Boulder This is achieved by remelting pig iron often along with substantial quantities of steel and scrap iron removing undesirable contaminants adding alloys and adjusting the carbon content.
Some pig iron grades are suitable for producing ductile iron. These are high purity pig irons and depending on the grade of ductile iron being produced. These pig irons may be low in the element silicon manganese sulfur and phosphorus these types of pig irons are used to dilute all the elements except carbon in a ductile iron charge.Also See: Pig Iron, Pig Irons, Ductile Iron, Carbon Content, Pig, Iron, Ingots
