The ceramic filter for aluminum is surrounded by a gasket, which can prevent the molten aluminum from leaking through the interface. AdTech ceramic foam filter uses three different types of gaskets, namely fiber paper material, fiber cotton material, and expanded cotton material. It can effectively remove various impurities in the aluminum melt, greatly improve the […]

Hydrogen is a harmful gas in molten aluminum. The pre-furnace detection of hydrogen content in molten aluminum is to ensure the quality of castings. Especially in the precision die casting process, the use of liquid aluminum degassing equipment to remove hydrogen and slag will become essential. During the smelting process, aluminum metal reacts with water […]

The liquid aluminum degassing equipment mainly treats molten aluminum containing a certain amount of hydrogen and other residues (alkali metals, inclusions), and then removes it after being treated by a degassing device. The principle of hydrogen degassing of aluminum is that hydrogen will move from a high pressure area (in the melt) to a low […]

Liquid aluminum refining system is a degassing and purification treatment equipment which cleans metal by removing physical hydrogen gas and inclusions. The systems utilizing rotating gas sparging device have been available for optimal molten aluminum refining in the industry. Aluminium Degassing Machine refined the volume of nitrogen bubbles by improving the rotating nozzle in the […]

The purpose of degassing aluminium with nitrogen is to blow nitrogen into the molten aluminum to remove hydrogen. Nitrogen is ejected from the graphite nozzle of the rotary degasser and floats in the molten aluminum. In addition, degassing with nitrogen by aluminium degassing unit is also considered a very effective method for floating impurities. Two […]

The demand for higher-quality aluminum products is progressively on the rise, especially in cutting edge industries like aerospace. Degassing is a process used to remove the hydrogen from the molten aluminum. The most popular aluminium degassing with nitrogen method involves introducing nitrogen gas into the liquid aluminum. The hydrogen causing these inclusions is simply drawn […]

The molten aluminum degassing with nitrogen is usually introduced into the melt through a rotary degassing device. This degassing process is limited by the laws of thermodynamics; when purge bubbles are introduced into the melt, they float towards the surface, thereby collecting hydrogen. In the best case, these hydrogen-saturated bubbles leave the melt and reduce […]

The molten metal flows through a series of successively arranged integrated purification stages, including a slag removal stage, in which it is removed from the molten metal by woven refractory filters, thereby removing larger particulate impurities from the molten metal. The smelting stage removes the entrained and dissolved hydrogen metal from the molten metal, an […]

The alumina ceramic foam filter used for aluminum casting is one of the core components of the ceramic filter. It is a new type of porous functional ceramic material, which is covered with crisscross capillary pores (about 1 to 10 microns in diameter). This is the channel for filtration. This component is called the board […]

The CFF system uses special ceramic foam filters for casting, it can remove the inclusions generated between the refining system and the mold table. The ability of the ceramic foam filter to capture these inclusions is critical to maintaining a clean ingot during the metal solidification process. Therefore, the quality and productivity of downstream operations […]
