Purification method of molten aluminum is to rely on the adsorption produced by the refining agent to achieve the purpose of removing oxidized inclusions and gases. Purification Method of Molten Aluminum Purge with inert gas. Inert gas refers to a gas that does not chemically react with molten aluminum and dissolved hydrogen, and does not […]

Purification treatment of aluminum: The surface of the aluminum material has an uneven oxide film, which sometimes absorbs moisture, is mixed with dust, oil, and is coated with paint. When melting, the aluminum material is further oxidized in a high temperature environment, and the thickness of the oxide film increases, and it reacts with the […]

The oxide film and impurity particles suspended in the molten aluminum are difficult to completely remove in a furnace with a wide open surface. The effect of applying the flux with the powder spraying machine is better, but it is still difficult to achieve the purpose of comprehensively purifying the molten aluminum. Therefore, in addition […]

Molten aluminium purification purpose is to remove the gas (mainly hydrogen) and solid impurities (mainly alumina) in the aluminum liquid. Purification of molten aluminum requires the use of substances that can separate aluminum oxide from the molten metal and drive hydrogen into the molten pool, but do not dissolve in the molten aluminum itself. This […]

Furnace refining technology generally uses chloride salt, fluorinated salt carbonate powder solvents and air blowing refining protected by covering agents. The principle is to pass inert gas or active gas that is insoluble in the aluminum melt into the aluminum melt, or add chloride salt, thereby generating a large number of bubbles in the aluminum […]

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 […]

Porous ceramic filters filtration efficiency mainly has filtration accuracy, which refers to the particle size of the smallest solid impurity particles in the fluid medium. For ceramic filters, the filtration accuracy can reach 0.1Lm. The main factor that affects the porous ceramic filters filtration efficiency is the maximum pore diameter of porous ceramic filter elements. […]

Porous ceramics are a kind of microporous filter media. In the general sense, porous ceramics are ceramic filter materials made of refractory raw materials as aggregates and combined with binders that have been sintered at high temperatures. The structure has a large number of penetrations. The fine pores with controllable pore size. Compared with other […]

Rotary degassing purification method has become a recognized high-efficiency hydrogen removal technology for aluminum alloy melt at home and abroad, and is favored by more users. The method of spraying gas flux with rotating nozzles has become an important development trend of drilling alloy melt purification technology at home and abroad. In recent years, due […]
