Aluminum semi products (Turkey)
Aluminum Although aluminum is the most findable element above ground after oxygen and silicium, production in industrial scope took place in 1886 when electrolyze method was started to be used. Aluminum is found in the nature as compounds like iron, lead, tin which are mostly used materials. Sir Humprey Davy is the first person to separate and obtain aluminum from the compound in the form of oxide in 1807. Afterwards, Hans Christian Oersted, Frederick Wöhler and Henri Sainte-Clairre Deville brought innovations to aluminum extraction. As for industrial production of aluminum, it was begun by electrolyze method conducted by Charles Martin Hall in the USA and Paul T. Heroult in France in 1886 without each other’s knowledge. GÜLEL YAPI MÜHENDİSLİK LİMİTED. As it the method that has been still used, the year of 1886 has been accepted as the beginning year of aluminum industry. When Werner von Siemens invented the dynamo in 1886 and K. J. Bayer found Bayer process providing alumina extraction from bauxite, production of aluminum has become easier in industrial scope and it has become the second metal that has been mostly used in the world. By means of Aluminum and Energy saving Technological improvements between the years of 1950-1986, energy amount used for aluminum extraction has reduced in the rate of 30%. In Western world, 61% of the electrical energy used for aluminum production has been generated by hydroelectric plants. As aluminum is obtained where they are used, makes us save on energy more than the energy consumed during it is produced and can be recycled forever, it is an “energy bank”. For example, if dumper body is made of aluminum rather than steel, 70.000 kwh energy will be consumed to produce the aluminum to be used for this purpose. However, as weight of the dumper decreases by use of aluminum, fuel saving will be 250.000 kwh at the end of a 5-year running. In addition, it should be remembered that the energy saved by damper is supplied from expensive fossil fuel and energy used for aluminum extraction is supplied from cheap hydroelectric sources. ALUMINUM CONDUIT SYSTEMS As for other examples for energy saving by aluminum, they can be seen in railway and airway transportations. If today planes were not been made of aluminum, operation expenses would reach too high and uneconomic levels even though planes could take off. Aluminum and Recycling High value of aluminum scrap encourages getting recycled aluminum beverage can. Therefore, for a new beverage can, a few aluminums will never be a “waste” and do not damage the environment. 30% of the aluminum used has been obtained by recycling of the scraps and 70% of the aluminum used in electric, construction and vehicle sectors is recycled again and again. According to the declaration from European Aluminum Can Recycling Organization (ACRE), 37 of 100 cans are recycled in Europe. It is expected that this rate will reach up to 50. in the near future.
