Pig Iron

Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant.

Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces.

PreRish Tri is producing high quality Nodular/Ductile/Spheroidal Grade Pig Iron with low impurities and chemical compositions within fairly narrow ranges of specifications with the objective of optimizing customer’s costs due to non-addition of additives, standardization of process parameters, procedures, and minimization of rejects.

Product Details:

  1. Basic pig iron: used mainly in electric arc steelmaking
  2. Foundry pig iron (also known as haematite pig iron): used in mainly in the manufacture of grey iron castings in cupola furnaces
  3. High purity pig iron (also known as nodular pig iron): used in the manufacture of ductile [also known as nodular or spheroid graphite – SG] iron castings.

Composition and characteristics:

Pig iron contains at least 92% Fe and has a high carbon content, typically 3.5 – 4.5%.

Other constituents are given in the table below:
