From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less energy ...

18 January 2011 Steel Primer 5 However, the growth of minimills caused an increase in global scrap prices, which in turn led to research for substitutes of scrap, mostly produced from iron ore that could be used by minimills to produce a better steel quality. The most popular scrap substitutes are direct reduced iron (DRI), hot briquetted iron (HBI), and iron dynamics (IDI).

Pulverized coal injection is a method for improving the performance of a blast furnace. Background. Iron is a metal that 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 result in low prices.
