· Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.

The iron resource efficiency, for defining the degree of saving of natural iron resources in steel production process, was formulated. A standard iron-flow diagram of steel production process was .
· The description of the diagram says: “A study of iron and steel flows in 2000 in the European Union showed that an input of about 120 Mt of iron ore (of which 98 Mt was imported) yielded 98 Mt of primary crude steel (i.e. produced directly from iron ore and coke).A further 65 Mt, representing 40% of total crude steel production, were produced as secondary crude steel, produced from scrap .
Foundries pour molten cast iron or steel into molds to produce castings with the approximate shapes of the ﬁnal products. The U.S. iron and steel industry and ferrous foundries produced goods valued at about $57 billion in 2002. About 90 companies produced raw steel at about 139 locations with a combined raw steel production capability

· 21. 4/27/2015 22 Introduction - Production of Iron & Steel Steel is essential to everyday life cars, trains, buildings, ships, bridges, refrigerators, medical equipment, for example, are all made with steel. Raw Materials - A blast furnace Uses iron ore, coke (made from specialist coking coals) and small quantities of limestone (iron ore, coke .
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved .
· The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and .
· Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
Iron and steel scrap is a vital raw material for the production of new steel and cast-iron products. The steelmaking and foundry industries in the United States are highly dependent upon the ready availability of scrap from manufacturing operations and from the recovery of products that are no longer used or needed. The steel industry has been recycling steel scrap for
Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron
