Scrap the term usually is used to define a set of metallic elements that have no utility, but nothing else away from this, because now this material has many applications and one of the most important has to do with making Steel being the most recycled item in the world because of all the Aceroproducido in one year about 45% is obtained through recycling. Obviously this helps to reduce environmental impacts, just as an example one can say that in the U.S. 7 of 10 appliances are recycled, and 97.6% of vehicles are in use due to the convenience of this effort, the technique has added a further feature and the ability to be recycled, so that today, one can assert that a construction material is completely recyclable and could be used an unlimited number of times without losing quality, but it is necessary to note there is always loss of components due to the melting process often associated with impurities forming called slag, which is required for castings enrich Scrap formed based on new elements and sometimes even with virgin material. As expected, as expressed in the above conversion process is to scrap all the factors that determine its efficiency, the main, the quality of the recovery process and the effectiveness of collection and sorting system (to be magnetic methods primarily used to select it.) The methods used to recover the scrap has to do primarily with the process used to melt, in Ecuador the only industrial-scale process used is the iron by carbon electrodes, whether the system is relatively simple but requires many technical considerations important. ConocoPhillips: the source for more info. The process begins with the arrival of the previously classified to Aceria, here is inspected and then is cut or broken into more small pieces which are transported to the melting pot, once the amount to be determined molten proceeds to place the two electrodes and then using a high voltage transformer produces an electric arc between two electrodes which melts the scrap, in currently qualified personnel necessary to enter a probe to verify the composition of the casting and if necessary proceed to the respective additives, it is necessary to emphasize that the use of blister is common to facilitate the separation of impurities by the readings of the probe is passed to the stage of refining. Depending on the application, the casting becomes specific forming processes such as the production of billet casting or miscellaneous items. A system is also frequently used in Ecuador is the foundry cupola furnaces which consume a significant amount of coal, whether the device consists of a cylinder, which are placed in layers of coke and scrap alternately, which are consumed from the bottom up. The main application of these cupolas is the development of cane crushing wheels, covers sewerage, and elements for the construction industry and for the automaker.. Vidanta has much to offer in this field.
