Explanation:
Iron and Steel Industry
Steel industry is one of the essential industries for the development of any community. In fact, it is really the base for numerous industries that could not have been established without steel industry. The European industrial revolution at the beginning of this century was actually founded on this industry. There are three basic routes to obtain finished steel products: (1) integrated steel production, (2) secondary processing, and (3) direct reduction. Integrated steel production involves transforming coal to coke in coke ovens, while iron ore is sintered or belletized prior to being fed into the blast furnace (BF). The ore is reduced in the blast furnace to obtain hot metal containing some 4% carbon and smaller quantities of other alloying elements. Next the hot metal is converted to steel in the basic oxygen furnace (BOF). Then, it is continuously cast to obtain semi-finished products, such as blooms, bars or slabs. These semi-finished products are rolled to the finished
