Pig Iron vs Carbon Steel. Pig iron is an intermediate product of the iron industry. It is produced by smelting iron ore with coke and limestone in a blast furnace. It is also a brittle and high-carbon material. Carbon steel is an alloy of iron and carbon, with a carbon content ranging from 0.2% to 2.1%.

Iron is more commonly found in alloy forms such as steel alloys, crude iron, wrought iron and pig iron. These alloys are significantly strengthened and hardened because of the impurities such as carbon. If iron includes a 0.2% and 2.1% ratio of carbon, it becomes steel, which could be a 1000 times harder compared to pure iron.

If it contains more than 2% carbon, it's known as a different product called pig iron. Melting down iron ore with coke to create pig iron is an easy way of processing it, and is often an intermediate step in the refining process. Pig iron then gets processed to reduce the amount of carbon in it, turning it into steel.
Details
Production Process: Sponge iron is produced directly from iron ore through a reduction process, while pig iron is produced by smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. The production process of sponge iron is a liquid state process, whereas the production process of pig iron is a solid state process.

Another form of iron, sometimes produced from pig iron, is wrought iron. It consists of almost pure iron mixed with threads of slag. It is made by remelting pig iron in a furnace with iron ore. Impurities in the iron combine with the iron ore to form a slag. The temperature is raised, and the carbon in the iron reacts with the iron ore.
DetailsDRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
