The working principle of aluminum casting flux purification is adsorbing and dissolving the oxidized inclusions in the aluminum melt, and floating to the surface of the molten aluminum through the density difference. The aluminum casting flux purification process is a complex multiphase process, which is restricted by many factors, the most important of which is […]

The aluminum casting flux chemical composition is mostly halogen salts, which are heterogeneous inclusions relative to the aluminum melt. After the melt purification is completed, it must be allowed to stand for a period of time to float or settle, and then separate from the aluminum liquid. Taking Na3AlF6 and Na2SiF6 as examples, Na3AlF6 produces […]

As we all know, Alu melt purification is generally divided into furnace purification and online purification according to the time sequence of its purification treatment. Furnace refining refers to the process in which the aluminum alloy melt is refined in the furnace to achieve the effect of purifying the aluminum alloy melt. Its working principle […]

Due to the repeated regeneration of aluminum, the secondary aluminum production process has attracted more and more countries’ attention. With the continuous progress of science and technology, the secondary aluminum industry is developing in the direction of scale, mechanization, automation, specialization, intensification and reduction of environmental pollution. Development Trends of Secondary Aluminum Production Process Actively […]

The purification technology of aluminum and aluminum alloy melt can improve the quality of secondary aluminum. The hydrogen content and non-metallic inclusions in aluminum and aluminum alloy melts have an important impact on the quality of secondary aluminum. Therefore, the aluminum and aluminum alloy melt must be purified. A common method for purifying aluminum and […]

CFF ceramic foam filter plates are popular because of their low cost, compact structure, simple operation, and better filtering effect. Compared with the corundum tube, the CFF ceramic foam filter has a larger pore diameter, a smaller density, and a lower filtration accuracy. Compared with the deep-bed filter, the filter layer is thin, and there […]

The smelting process of waste aluminum determines the performance of secondary aluminum products. The aluminum melt production process is roughly as follows: batching-furnace loading, melting-alloying-stirring-furnace treatment-on-line treatment outside the furnace (degassing, filtering, etc.)-casting. The treatment in the furnace is one of the key processes that affect the quality of molten aluminum, which mainly includes the […]

The molten aluminum purification stage refers to the process in which liquid aluminum is transferred from the static furnace into the launder, after online degassing, ceramic foam filter molten metal filtration, etc., filling the draft tube and keeping it for a certain period of time. At this stage, the three elements required for casting: casting […]

The aluminum hot-top casting process is selected for the production of aluminum alloy round ingots, it has the advantages of excellent internal and surface quality of the ingot and easy production and operation. Under the condition that the composition of the alloy and the hot-top casting process equipment are determined, the casting process parameters are […]

The aluminum ingot produced by hot top casting has a uniform structure and good mechanical properties. In order to obtain such a casting structure, aluminum ingot hot top casting is used for round ingot casting. The quality of aluminum alloy ingots has an important impact on the subsequent processing procedures and the quality of aluminum […]
