Pig iron

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 molds used for pig iron ingots was a branching structure formed in sand, with many individual ingots at right angles to a central channel or runner, resembling a litter of piglets being suckled

What Is Involved in Pig Iron Production? (with pictures)

13/1/2021Pig iron production is generally only one step in the creation of a finished iron product, since the high carbon content of iron in this form makes it mostly unusable. To make it more versatile, it can be melted again and mixed with slag, creating wrought iron, or combined with additional iron ore and alloys to create cast iron.

Iron Production

Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.

Abstract: Iron sand as the largest form of iron ore reserves in Indonesia has not been optimized properly for domestic iron-steel production. In the production chain of pig iron from iron sand, there is a problem that in sponge iron (result of direct reduction) contains many impurities, especially titanium.

Hurstwic: Iron Production in the Viking Age

The iron ore shown to the right was excavated from Skgar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.

Pig iron

Pig iron is an intermediate product of the iron industry in the production of steel, also known as crude iron, which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, [1] along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

Iron Making

The majority of pig iron produced by blast furnaces undergoes further processing to reduce the carbon content and produce various grades of steel used for tools and construction materials. Although the efficiency of blast furnaces is constantly evolving, the chemical process inside the blast furnace remains the same.
