Ceramic foam filter of aluminum is used to remove the oxide inclusions and provide high-quality molten aluminum for the casting process. Before the ceramic foam filter (CFF) filters the molten aluminum, it is necessary to fully preheat the ceramic sheet and the filter box to ensure that the molten aluminum can pass through the filter […]

Launder for Casting is an important part of the aluminum casting process. After the molten aluminum in the holding furnace is processed in the furnace, it is transferred from the holding furnace to the online refining device, and then enters the casting machine through the launder for casting. Since the liquid level control accuracy is […]

Nitrogen degassing aluminium is used for gas blowing refining, it has the characteristics of convenient operation, environmental protection and safety, and low cost, but the refining effect is restricted by the purity of the inert gas itself. Generally, inert gases will always contain a certain amount of moisture and oxygen even if strict purification measures […]

Aluminum degassing system adopts a dual-rotor gas refining device, which refining gas is blown through the rotating nozzle to generate tiny bubbles. The rotating nozzle is made of graphite. The nozzle structure design takes into account the uniform ejection of bubbles. The rotating impeller is also used to break the bubbles, increase the contact area […]

CFF Filtering System consists of a heater cover, an electrical device, and ceramic foam filter box. The on-line filter box contains molten metal and is designed to support the ceramic foam filter and provide metal circulation space. The CFF filter box has two chambers for capturing impurities in the molten metal, and one metal inlet and […]

Aluminum liquid filtration generally uses foam ceramic filter filtration. When the aluminum liquid passes through the tortuous and interconnected pores in the foam ceramic, the internal debris is deposited on the wall of the pore under the action of fluid power, inertia, interception, collision, and adsorption. So that the clean aluminum liquid enters the casting […]

In the late 1970s, the United States made a sponge-like ceramic foam filter (CFF) made of alumina and chromium oxide. CFF filter for molten aluminum not only has good purification technology, but also is easy to use. The initial pressure difference through the melt is only 100-150mm, and once it passes, it only needs to […]

Ceramic foam filter for molten metal filtration is used as a means of separating finely divided solid impurities suspended in the melt. For this purpose, it is recommended to use a refractory bed, compacted loose filter material block or screen. It has also been proposed that ceramic foam filter can be used as a filter […]

Flux purification for molten aluminum is an important part of melt purification. It is one furnace purification method, is the basic guarantee for melt purification. When the flux acts on the surface of the aluminum melt, the flux will absorb the scum on the surface of the melt and play a role in removing slag. […]

Ceramic foam filter molten metal filtration has great advantages in reducing production costs and improving product quality. In addition, ceramic foam filters are used to purify molten aluminum. It is arranged horizontally in the CFF filter box, that is, between the launder and the casting well. Moreover, a ceramic foam filter plate can effectively filter […]
