About Pig Iron

Pig Iron is produced from the first smelting of Iron Ore. The melt of the blast furnace is run off into rectangular moulds, traditionally in a branching structure running off a central runner, with the moulds at right angles to each other. This configuration is similar to piglets suckling on a sow, hence the ingots are referred to as pigs.


​Pig Iron is either sand-cast or machine-cast. When it is sand-cast, it has sand adhering and fused into the surface, giving more slag in the melting. Machine-cast Pig Iron is cast in steel forms and has a fine-grained chilled structure, with a lower melting point.


Read below as we describe Westbrook’s Pig Iron, its properties and uses, and why Westbrook Resources should be chosen as your trusted supplier of Pig Iron.

Key Properties of Pig Iron

Pig Iron has a high Carbon content, typically 3.5% – 4.5% along with small percentages of Silicon, Sulphur, Manganese and Phosphorus. This makes Pig Iron brittle and only really useful for re-smelting to make Cast Iron, Wrought Iron or, nowadays, steel.


Uses of Pig Iron

Pig Iron can be used to produce Grey Iron and high purity Pig Irons can be used to produce Ductile Iron.


In modern steelmaking, Pig Iron/slag is transferred, in liquid form referred to as “hot metal”, from the bottom of the blast furnace into a steel-making vessel, typically with an electric arc furnace, induction furnace or basic Oxygen furnace by burning off the excess Carbon and adjusting the alloy composition.


Pig Iron may also be used in the production of Ductile Iron that is low in Silicon, Manganese, Phosphorus and Sulphur. Read below why you should choose Westbrook as your Pig Iron supplier.

Where does the name ‘Pig Iron’ come from?

The term ‘Pig Iron’ dates back to when hot metal was utilised and cast into ingots before being sent to the plant. In order to be fed from the common runner, the moulds were laid out in sand beds. This group of moulds resembled piglets suckling on a sow, hence the nickname ‘Pig Iron’.

What advancements have been made in the production of Pig Iron?

Blast furnace technology, raw material quality and waste management have all seen desirable advancements in the production of Pig Iron over recent times. Each modern technique improves the efficiency and the environmental performance of Pig Iron production.


Is there any significance in the history of Pig Iron?

The production of Pig Iron played a pivotal role in the Industrial Revolution. Pig Iron supplied the raw material for the development of railroads and machinery, which aided the growth of the economy. To this day, Pig Iron continues to play a significant role in the steel industry.
