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. […]

Aluminium Foundry Casting line for the production of posts from aluminum by the method of heat nozzle. 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 […]

Factors affecting foundry aluminum casting loss include liquid aluminum temperature, contact strength between liquid aluminum and oxygen, and aluminum content in aluminum slag. Ways to Reduce Foundry Aluminum Casting Damage 1. Control the temperature of liquid aluminum The melting point of aluminum is 660 ℃. Generally speaking, the casting temperature of primary aluminum is controlled […]

The main external manifestations of aluminum casting loss can be divided into two parts: one is pure aluminum ash form, and the other is bulk aluminum and defective aluminum and aluminum slag. According to the statistics of the melting casting workshop, the non-recyclable pure aluminum ash accounts for about 90% of the casting losses (oxidation, […]

Aluminium alloy is an alloy with aluminium as the main material. The alloy elements include copper, silicon, magnesium, zinc, etc. Aluminum alloy has the advantages of corrosion resistance, easy processing, high strength, and low density. Aluminium alloy has so many advantages, how it is processed into various aluminum alloy products. Nowadays, the extrusion process and […]
