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

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. Most often, pig iron production is an intermediary step on the road to creating steel, which involves a second burning process to remove many of the remaining impurities, and the ...

Iron-Making, Indirect Process | SpringerLink

The technique of smelting iron ore in a furnace at a very high temperature to yield a molten, high-carbon form of iron. The high-carbon content makes it too brittle for most direct uses, so it must undergo a secondary process, oxidization, to make it more ductile. It can then be forged into weapons and tools.

SLAG IN THE PRODUCTION OF WROUGHT IRON

Direct reduction processes of production of wrought iron from iron ore have take place at about 1200°C. At those temperatures slag has to be liquid. The objective of our re-search was to describe mechanisms of wrought iron production. METHODOLOGY Two slag, primary and final, are formed during the reduction process in making pig iron.

The Steel Manufacturing Process - How is Steel Made?

Steel is a discovery of the Iron Age, a period that started around 1200 BCE. Iron ore was first mined in Central Asia and Europe, and humans at this time used iron to make tools and weapons in a practice called ferrous metallurgy. Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods.

Sponge Iron - an overview | ScienceDirect Topics

In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface, hence the name "sponge iron." The commercial process is a solid solution reduction, also called direct-reduced iron (DRI). In this process, the iron ore lumps, pellets, or fines are heated in a furnace at 800–1500°C (1470–2730 ...
