Iron and Steel ProductionIn this project, I researched the production of iron and steel. I will look in detail at how both are made, what they are made of, and other facts. on both metals.During ironmaking, iron ore, coke, heated air, and limestone or other streams are fed into a blast furnace. The heated air causes the coke to burn, which provides the heat and carbon sources needed to produce iron. Limestone or other fluxes may be added to react and remove acidic impurities, called slag, from the molten iron. Limescale-impurity mixtures float to the surface of the molten iron and are skimmed off, see Figure 1, once the melting is complete. Sintering products can also be added to the oven. Sintering is a process in which solid waste is combined into a porous mass which can then be added to the blast furnace. These wastes include iron ores, antipollution dusts, coke breezes, water treatment plant sludges and fluxes. Sintering plants help reduce solid waste by burning the waste and capturing traces of iron present in the mixture. Sintering plants are not used in all steel production facilities. Steel is made via two basic routes: from raw materials including iron ore, limestone and coke, as well as recycled steel from the basic blast furnace and oxygen furnace, or from of recycled steel via the electric arc furnace method. In 2001, more than 435 million tonnes of steel were recycled. Steel is the most recycled material in the world. More than 25% of a steel can contains recycled materials. Steel is not a single product. There are currently over 3,500 different grades of steel......paper......that have been around for over 2,000 years. Steel is still produced using technology based on the Bessemer process which involves blowing air through molten iron to oxidize the material and separate impurities. With a production of more than 43 million tonnes in 2001, the European company Arcelor produces the most steel. In 2001, China produced With more than 149 million tons of crude steel, China is the largest consumer of steel in the world with more than 170 million tons. Rust is the product of corrosion. When steel comes into contact with water and oxygen, a chemical reaction occurs and the steel begins to return to its original form: iron oxide. Today's steel can be protected against rust. A typical example is the extended warranties offered by automobile manufacturers on steel body panels...
