Description
Wrought aluminium alloy ingots are subsequently usually further processed by processing enterprises through rolling, extrusion, drawing, forging, etc., and can be used in the following applications and/or processes: automobiles, household appliances, construction, machinery and household products. The product system boundary covers the mining and manufacture of raw materials and the output of the aluminium alloy ingot product, including production units such as the upstream mining and manufacture of raw materials, the sorting and water washing of feedstock, dissolution, refining, ingot casting and packaging, as well as upstream stages such as the production and transport of auxiliary materials and energy (fuel, electricity). The proportion of aluminium scrap in this product is 100%. The data inventory is formed by merging data from multiple sources, and has been optimized according to expert opinions and the best available information.
Activity Description
The production process of aluminum alloy ingots includes the sorting and washing of raw materials, melting, refining, and ingot casting. After the raw materials and auxiliary materials are sorted, washed and dissolved, they are refined and cast according to the alloy proportion to produce aluminum alloy ingots. This process covers energy consumption, material consumption, waste disposal and environmental impact during the production of aluminum alloy ingots.
Process Description
Aluminum alloy ingots are aluminum alloys composed of primary aluminum and metal additives, and are divided into round ingots and flat ingots. According to their performance and usage characteristics, they can be categorized into anti-corrosion aluminum alloys, hard aluminum alloys, superhard aluminum alloys, forged aluminum alloys, and special aluminum alloys. Based on their sensitivity to heat treatment, they can be further divided into two categories: heat-treatable aluminum alloys and non-heat-treatable aluminum alloys. Generally, aluminum alloys used for structural purposes belong to the category of heat-treatable alloys. To ensure good workability, the microstructure should be dominated by an aluminum-based solid solution. Therefore, alloying is constrained by workability. These alloy materials are mainly used in aerospace, space technology, and portable electronic devices, and are also widely employed in the automotive industry and machinery manufacturing for producing parts that operate under sliding friction conditions.
