Exploitation of chips and scrap aluminum through physical processes for the development of aluminum sheets and bars

Abstract

Colombia manufactures metals such as iron and aluminum, which consume a lot of energy to carry out these processes. There are many techniques to recycle metals and other elements to reduce the amount of energy in manufacturing processes, since smelting is generated with already manufactured materials, as in the case of aluminum, which uses recycled products such as soft drinks and beer cans. In addition, there is another type of scrap metal, such as aluminum shavings generated by machining processes, with an amount that varies from a small percentage to 70-90% of the original part. This project seeks to transform the aluminum shavings through physical processes with the application of temperature in aluminum material to be used again. The process begins with the collection of chips from mechanical workshops, in this case, from the machine tool laboratories of the “Universidad Francisco de Paula Santander, Ocaña, Colombia”. Standard procedures will be carried out before the casting process by developing firing curves and phase diagrams of aluminum, where the research focuses on generating aluminum metal to be used again in the laboratories of the same university.

Advanced Fabrication and Multi-Properties of Aluminum-Based Aerogels from Aluminum Waste for Thermal Insulation and Oil Absorption Applications

“…The high demand of aluminum results in a large amount of aluminum waste from production lines and end-of-life products. It is estimated that at least 20% of aluminum is lost as chips and scrap during the manufacturing process [ 10 ]. According to the U.S. Environmental Protection Agency, the amount of aluminum packaging and beverage cans sent to landfills and incinerators are 2.7 million tons and 0.6 million tons, respectively [ 11 ].…”

Manufacture of reinforced nano metal melt aluminum sponges for oil collection in spill from water sources

“…Various techniques such as powder metallurgy, hot extrusion, smelting and agglomeration by electromagnetic induction furnace are generally analyzed. Therefore, the decision is taken to develop techniques in an experimental way that guide us towards the development of these techniques [7][8][9]. Using the study of physical processes that allow the development of techniques to carry out a good process of recycling and use of metal materials that have not been reused so far [10,11].…”
