Pulverized coal injection method - Wikipedia
Iron is a metal which has fundamentally affected the way of life of human beings ever since the Iron Age. It is relatively abundant and can easily be extracted and modified due to its useful material properties, all of which results in low prices. After the industrial revolution (18-19th century), iron became a core material of industrial markets, its importance reflected in the phrase “iron is nation”; its production was directly regarded as an indication of national power. Especially after World War II, governments vigorously supp…
