New, green technologies will increase the use of DRI. Direct reduced iron (DRI) accounts for 5 percent of the metallics used in the steelmaking process globally (Exhibit 1). It is currently used less commonly than pig iron or steel scrap. Traditionally, DRI is produced from the direct reduction of iron ore using natural gas, but emerging ...

Pig iron is later processed, to form steel billets, by heating in arc furnaces. Iron ore serves as the primary raw material for manufacturing a wide range of steel products. Coal/coke: Bituminous coal is heated at °C in a blast furnace, to drive off impurities, leaving nearly pure carbon. The furnace is blasted with a hot blast of ...

The process gases carbon monoxide ( CO C O) and hydrogen ( H2 H 2) are blown into the furnace at temperatures of approx. 1000 °C and flow through the iron ores. The reduction of iron oxides takes place according to the following chemical equations: Fe2O3 Fe2O3 + 3CO + 3H2 → 2Fe → 2Fe + 3CO2 + 3H2O (1) (2) (1) F e 2 O 3 + 3 C O → 2 F e ...

Using steel scrap also helps reduce waste. Instead of sitting in a junkyard, items can be recycled and the steel can be separated to obtain scrap. Alloy steel made using steel scrap is also just as strong and durable as steel made from raw material using iron ore. Steel does not suffer from a loss of quality when recycled or made from steel scrap.

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...

The quality of these materials has direct bearing on the process as well as the product. Some plants do not use iron ore directly. These plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore, dolomite and noncoking coal is fed at the one end of the rotary kiln and is heated by coal burners to produce DRI.

The coking process creates coke gas, which is a valuable, energybearing commodity and so is reused, providing heat for the coke ovens. It can also be used to produce electricity. The other byproducts, tar, sulphur, ammonia, naphthalene and benzole, are also captured and are sold to the chemical industry. Nothing is wasted.
