Ceramic Foam Filtration is widely used for molten aluminum filtering. Molten aluminum filtering is an important step in the aluminum casting process. After the aluminum melt is refined in the smelting furnace, refining in the static furnace and online refining, the gas content has been greatly reduced, and it is basically in the critical minimum […]

Degassing With Inert Gas is widely used in the metal casting process. The melt and dissolved hydrogen do not react with chemical reactions and do not dissolve in aluminum, such as nitrogen and argon, usually using nitrogen. When the inert gas is blown into the melt, many fine bubbles are formed. When the bubbles pass […]

Methods Of Degassing In Foundry main include flux refining and degassing with inert gas. Inert gas is continuously blown into the melt, and the refining method in which the oxidized inclusions and hydrogen are brought to the liquid surface during the floating of the bubbles is called inert gas refining. The reason why blowing inert […]

Degassing with Nitrogen has been gradually eliminated in the modern aluminum industry, fluxes are generally used together with nitrogen. Use active gas chlorine as a purifying agent (chlorination method). In the chlorination method, when the chlorine gas is passed into the aluminum liquid, a lot of abnormally small bubbles are generated, which are fully mixed […]

The process and operation process of removing gas, inclusions and harmful elements from the melt to obtain pure aluminum liquid is called refining. Some people call it purification. There are many refining methods for aluminum alloy, which can be divided into three types according to refining position: pre refining before furnace (such as ladle refining), […]

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 […]
