On an operating cost basis, U.S. integrated mills typically are lower cost than their minimill peers. Scrap prices are tied to the marginal cost of hot metal production—meaning that the input for scrap-based steelmaking is typically higher than the average ironmaking bulks mix (iron ore, coal and coke).

Introduction. A blast furnace is a special type of cylindrical furnace, which is basically used for the purpose of smelting. So, the industrial metals can be extracted from their ores like iron, pig iron, or copper. The word 'blast' gives the idea of combustion air which is forcefully supplied or produced to the atmospheric pressure above.
