Recent survey data from the Brazilian Aluminum Association show that more than 96% of the aluminum cans consumed in the country are recycled, with the highest recycling rate in the world. According to the survey, it takes only 60 days on average for an aluminum can to be thrown into the trash can to return […]

Automobile manufacturer Audi Hungary announced that it will implement a closed-loop aluminum recycling project in 2021. The company uses 38,000 tons of aluminum in automobile production every year. Taking into account the energy-intensive nature of aluminum production, Audi Hungary tries to maximize energy efficiency by using recycled aluminum. Audi Hungary stated that the aluminum recycling […]

The purification effect of aluminum alloy melt is mainly determined by dissolved hydrogen and non-metallic inclusions. Hydrogen is the most important factor leading to the formation of porosity; non-metallic inclusions can become the heterogeneous core of pores and promote the formation of porosity. Due to the “uncertainty” of its behavior, the porosity changes greatly, which […]

The rotating degassing purification method uses a rotating nozzle to spray gas flux from the bottom of the aluminum alloy melt. During the rotation of the nozzle, the fluid sprayed from the nozzle blades produces a strong stream, which can produce more than a single tube Or multiple tubes with smaller bubbles, at the same […]

Although there are many process methods for the refining of aluminum alloy melt, they still cannot meet the production needs of the aluminum industry, especially the production of military aluminum alloys such as aerospace. At present, refining and purification in the production process of cast aluminum alloy is still a basic problem, it has not […]

The principle of SNIF purification is to blow inert gas or inert gas containing a small amount of chlorine into the melt. During the purification process, the aluminum alloy melt enters the first purification zone through the population of the device, is purified by the rotating nozzle, and then enters the second purification zone through […]

Furnace treatment is mainly used in small and medium-sized aluminum processing plants, not only the slag removal effect is not good, but also the melt has the possibility of secondary pollution. In order to improve the purification treatment effect and ensure the stability and reliability of the melt quality, continuous purification treatment outside the furnace […]

Flux refining method is to achieve the purpose of slag removal by adsorbing, dissolving oxide inclusions and adsorbing the hydrogen in molten aluminum, floating up to the liquid level and entering the slag. The flux is generally composed of a mixture of alkali metal or alkali metal halide. After the aluminum liquid is added, the […]

Purification treatment of aluminum alloy melt can be divided into in-furnace treatment and out-of-furnace treatment according to different production links. The purification technology in the aluminum alloy melt furnace can be divided into adsorption purification treatment technology and non-adsorption purification treatment technology. The adsorption method mainly relies on the refining agent to produce the effect […]

In the field of defense technology such as aerospace, the application of large aluminum alloy components is increasing, and the requirements for components are getting higher and higher. In addition to ensuring its chemical composition, mechanical properties and dimensional accuracy, castings are also not allowed to have defects such as shrinkage, porosity, leakage, and slag […]
