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 […]
The molten aluminum degassing equipment adopts compact furnace design. In the degassing box, a rotating nozzle is used to degass the molten aluminum, and convection is formed in the box so that small bubbles can completely diffuse into the molten aluminum. At the same time, the sealing design is adopted to prevent the secondary pollution […]
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 […]
Degassing process in aluminum can be divided into two situations: one is the hydrogen removal process that can form hydrogen bubbles; the other is the hydrogen removal process that cannot form hydrogen bubbles. The degassing process in aluminum that can form hydrogen bubbles can be roughly divided into three stages: first, the formation of bubbles, […]
Rotary degassing purification method is a kind of bubble floatation method, and it is also the most widely used aluminum alloy melt purification method. Rotary blowing degassing purification method by degassing unit is to pass inert gas in aluminum alloy melt in the aluminum alloy melt. It is broken and ejected at high speed when […]
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, […]
Aluminum Liquid Purification is important, because the electrolytic aluminum solution contains a large number of non-metallic inclusions and carbides, nitrides, and sulfides. When the electrolytic aluminum liquid directly enters the melting pool of the smelting furnace, it is easy to adhere to the refractory lining of the smelting furnace, and is closely integrated with the […]
Aluminium degassing machine most notable feature is the graphite stator and graphite rod/rotor structure. The graphite stator does not rotate in the molten aluminum and protects the graphite rod/rotor assembly. The graphite rod and the graphite rotor are assembled together to stir the aluminum water. The inert gas passes through the gap between the stator […]
