Pig Iron
Pig Iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Pig iron has a very high carbon content, typically 3.5–4.5%, along with silica and other constituents of dross. Merchant Pig Iron is cold iron, cast into ingots and sold as ferrous feedstock for the steel and metal casting industries. Merchant pig iron comprises three main types: BASIC Pig Iron used mainly in electric arc steelmaking, FOUNDRY Pig Iron used mainly in the manufacture of grey iron castings in cupola furnaces, and NODULAR Pig.
Iron used in the manufacture of ductile iron castings. Pig iron contains at least 92% Fe.
| Other constituents | Carbon | Silicon | Manganese | Sulphur | Phosphorus |
|---|---|---|---|---|---|
| BASIC | 3.5 - 4.5% | < 1.5% | 0.5 - 1.0% | < 0.05% | < 0.12% |
| FOUNDRY | 3.5 - 4.5% | 1.5 - 3.5% | 0.5 - 1.0% | < 0.05% | < 0.12% |
| NODULAR | 3.5 - 4.5% | < 0.05% | < 0.02% | < 0.04% |
