Cast iron is an iron alloy containing 2 wt.% – 4 wt.% carbon, 1 wt.% – 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

Pig Iron Production Blast Furnace Route. More than billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day.

The production of pig iron had the highest impact on GHG and fuel consumption due to electricity. They also showed that the iron ore sintering process was the highest contributor to dust and on GHG emissions. In future, LCA of alternative steel production technologies should be conducted, including thermodynamic analysis and exergy analysis.

· The Iron Revolution in History. British iron production in 1700 was 12,000 metric tons a year. This rose to over two million by 1850. Although Darby is sometimes cited as the major innovator, it was Cort's new methods which had the major effect and his principles are still used today.
