The aluminum alloy casting process is very complicated. In this process, there will be some impurities in the aluminum liquid. So, what are these impurities? What method should we take to remove these impurities, and get pure aluminum? Originally, the molten aluminum will only react with air to produce an oxide film, which is a […]

Alcan Smelter Aluminum Degassing is based on the principle that dissolved hydrogen gas will move from an area of high concentration (in the melt) to an area of low concentration (in the inert gas). Hydrogen gas disperses in molten metal as it would if it were released in any confined space. It will maintain a […]

Molten aluminum is extremely reactive, so when it comes in contact with moist air or wet tools, the water decomposes to release hydrogen in the melt. Excessive quantities of this dissolved gas have a well-documented detrimental effect on the mechanical properties of the final aluminum castings. What is also well known to anyone making castings […]

Metallurgy is to remove impurities (non-intentional elements) in the metal solution by melting (heating above the melting point) for slag formation and slag removal, while certain chemical components are relatively pure by slag removal, decarburization, deoxidation, etc. The process of alloy composition. The finer refining process for aluminium degassing treatment is generally a metal foundry. […]

A BRIEF DESCRIPTION Aluminium Foundry Casting line provided including： SPRUE BUSH DISTRIBUTING LAUNDER HAT PLATE TRANSITION PLATE GRAPHITE RING HOP-TOP CASTING DISTRIBUTING LAUNDER The proposed set of equipment of the Foundry line is equipment for casting high-quality workpieces […]

During smelting, aluminum melts are purified from dissolved metal impurities (sodium, magnesium, iron and zinc), suspended oxide (non-metallic) inclusions and dissolved hydrogen. In order to purify from dissolved metal impurities, degassing methods in casting, treatment with fluxes, and filtering is important. For these purposes, various methods of purging the melts with inert and active gases, […]

Electrolytic aluminum is aluminum obtained by electrolysis, it is an important aluminum extraction process. The modern electrolytic aluminum industry uses cryolite-alumina molten salt electrolysis. Molten cryolite is a solvent, alumina is used as a solute, carbon is used as an anode, and aluminum liquid is used as a cathode. After the powerful direct current is […]

The Bayer process for aluminum extraction is a chemical process widely used in the industry to produce alumina from bauxite. Bauxite is a sedimentary rock containing high aluminum content. Bauxite is often covered by several meters of rock and clay, which must first be removed before the bauxite can be recovered. Bayer process is invented […]

According to the casting process of molten metal, aluminum casting process is divided into gravity casting process and pressure casting process. Gravity casting refers to the process in which the molten metal is injected into the mold under the influence of the earth’s gravity. Pressure casting refers to the process in which the molten metal […]

In the smelting process of aluminum and aluminum alloy, in addition to its own inclusions, aluminum is very easy to form alumina or sub-alumina with oxygen. It results in a layer of scum on the surface of the molten aluminum, which has a certain wettability with the aluminum melt, and a considerable amount of molten […]
