Recycled aluminum alloy contains more metal and non-metal impurities and must be further refined. Impurities refining methods include ceramic foam filter filtration, gas refining, flux refining, vacuum refining, and oxidation refining. The first four methods are used to remove non-metal impurities, and the latter method is used to remove metal impurities. When the regenerated aluminum […]
The purification treatment of aluminum alloy melt is one of the basic guarantee measures for the production of high-quality aluminum castings, and it is also the main means to improve the comprehensive performance of aluminum alloys. The refining effect of aluminum alloy melt has an important influence on the formation of porosity, pores and inclusions, […]
The smelting of aluminum alloy is an important part of the aluminum alloy processing process, which is reflected in the smelting process’s alloying, purification, and refinement processing technology. Alloy purification mainly adopts furnace flux refining and external foam ceramic filter to remove non-metallic inclusions in aluminum alloy melt, which has long become an important means […]
Aluminum is a very active metal, which easily reacts with water vapor during the smelting process to generate hydrogen and oxide inclusions (Al2O3). These non-metallic inclusions are very harmful to the performance of aluminum products. Therefore, the purification of aluminum melt is one of the main ways to improve the quality of aluminum products. The […]
According to the actual production situation of cast rolling, the dissolved hydrogen is the most easily dissolved gas in molten aluminum, and its content accounts for 90% of the dissolved gas. Hydrogen is an important cause of porosity, loose strip and peeling in casting and rolling and the next process (aluminum alloy is easy to […]
With the development of various industries in the society, the demand for aluminum alloy has gradually increased, so the aluminium refining process is also particularly important. Aluminium Refining Process Loading. The pre-made alloy ingots and high-quality reheating materials, and then the fol alloy is added, and the alloy elements are added later. Temperature control. Strictly […]
Purification method of molten aluminum is to rely on the adsorption produced by the refining agent to achieve the purpose of removing oxidized inclusions and gases. Purification Method of Molten Aluminum Purge with inert gas. Inert gas refers to a gas that does not chemically react with molten aluminum and dissolved hydrogen, and does not […]
Purification treatment of aluminum: The surface of the aluminum material has an uneven oxide film, which sometimes absorbs moisture, is mixed with dust, oil, and is coated with paint. When melting, the aluminum material is further oxidized in a high temperature environment, and the thickness of the oxide film increases, and it reacts with the […]
Deslagging Flux has the ability to absorb inclusions to float to the surface of the molten aluminum and form dry slag. The compound in the flux reacts with the impurities in the aluminum liquid, so that the oxide becomes more stable, and it is easy to generate high-temperature oxides with a smaller affinity for molten […]
Slag remover belongs to a processing flux for purifying aluminum alloy melt. It is composed of a variety of chlorides and fluorides. It has not only a remarkable slag removal effect, but also degassing and covering functions. Slag removal and degassing are the two central links and ultimate goals of aluminum alloy melt purification treatment, […]
