Aluminum melt refining process, the refining volume, temperature control, standing time and other factors have an impact on the quality of aluminum alloy melt. Aluminum Melt Refining Process During the smelting process, tools and other factors have an impact on the quality of the aluminum alloy melt. It must be baked before use. It cannot […]

Aluminum smelting process must be strictly controlled, so as to obtain high-quality aluminum alloy castings. With the development of science and technology, automotive, shipbuilding, aviation, aerospace and other manufacturing industries have increasingly higher quality requirements for aluminum alloy castings. In addition to ensuring chemical composition, mechanical properties and dimensional accuracy, castings are not allowed to […]

Aluminum Smelting and Refining: In the process of aluminum alloy smelting, a refining agent is added to the furnace for processing, so it is called “refining”. In aluminum and aluminum alloy melts, refining agents can remove metal impurities, oxides and other oxide inclusions from the melt through physical, chemical or physical-chemical interactions. It is determined […]

During the molten aluminum refining process, the hydrogen atoms dissolved in the molten aluminum undergo migration to the periphery of the refining bubble (Ar or N, etc.), and are adsorbed around the bubble and associated with hydrogen molecules to enter the bubble, and finally float up with the bubble. Kinetic process such as aluminum tapping […]

Melt refining is one of the most common and effective means to obtain clean liquid metal. Obtaining clean aluminum alloy melt is the guarantee and prerequisite for obtaining high-quality aluminum alloy castings. Hydrogen is the main source of stomata in aluminum alloys. Correctly understand the source of stomata (including the source of hydrogen, the way […]

Aluminum alloy refining process is an important step in aluminum alloy casting. Flux refining is usually used in the furnace. According to the crucible smelting and the weight of the charge, the charge, alloy ingot, intermediate alloy, and pure metal are added to the crucible one after another or at the same time and heated […]

Impurity elements refining in molten aluminum is removing iron and other impurity elements. Iron is the main impurity element in aluminum alloy. In the 6063 alloy, the national standard stipulates that it is not more than 0.35. If first-class industrial aluminum ingots are used in production, the iron content can generally be controlled below 0.25. […]

Aluminium Degassing Process: In addition to hydrogen, it is necessary to prevent moisture and various dirt from entering the crucible or furnace, but also to eliminate oxide inclusions and hydrogen in the aluminum liquid. Because only by effectively removing the dispersed inclusions suspended in the molten aluminum, can the molten aluminum be prevented from increasing […]

Refining agent degassing is currently the most commonly used method in aluminum plants to eliminate pinholes in aluminum alloy castings. In order not to cause a large amount of splashing of the aluminum liquid, the degassing agent can be added in batches, and the degassing ends the slag removal. When aluminum alloy is smelted, it […]

Rotary Degassing Aluminum works by rotating nozzle of degassing unit. The rotating nozzle has a rotating shaft, a rotor with blades (connected to the rotating shaft), and a stator with blades. Their interaction can provide the desired bubble shape for the melt. The refined gas emerges into the aluminum melt through the small gap between […]
