The refining property of foundry fluxes refers to the ability of the flux to absorb and dissolve the oxide inclusions in the molten aluminum. The conditions for the flux to automatically adsorb oxidized inclusions are the interfacial tension between the melt and the flux and the interfacial tension between the melt and the impurities. Because […]

The online degassing equipment mainly processes molten aluminum that contains a certain amount of hydrogen and other residues (alkali metals, slag inclusions), which are removed after being processed by the degassing equipment. The online degassing equipment of aluminum melt uses the impeller of the graphite rotor to break up the bubbles in order to obtain […]

The deep-bed filter is a new type of filter device developed in recent years. It is composed of multiple layers of alumina balls and a layer of alumina grit of appropriate size. The size and stacking method of alumina balls and gravel are determined according to the quality requirements of the final product. The combination […]

The main advantage of the ceramic foam filter system is to effectively eradicate the slag generated during the transfer process outside the furnace through the filter plate. Remove micron-sized inclusions in molten aluminum. At the same time, because the ceramic foam filter plate filters out fine inclusions, reduces the effective number of crystal nuclei in […]

Aluminium liquid filtration is to use a filter with many pores as a medium to allow liquid aluminum to pass through the pores and to intercept solid particles on the other side of the medium to achieve the purpose of separation. The medium used for filtration is called the filter medium. The small holes in […]

The Foam Ceramic Filter for Foundry is installed in the CFF filter box between the furnace mouth and the distributing launder. The filter box is made of refractory material. It can pass thousands of times of chilling and heating without cracking. It has the advantages of high strength and good insulation performance. It is currently […]

The deep bed filter adopts a metal box structure with high performance heat insulation lining and refractory casting lining. The box is sealed by the upper heating cover, and the heating cover also preheats the filter. The box body is generally composed of two cavities, the inlet cavity is equipped with a filter layer, and […]

The aluminum degassing device can realize the continuous degassing of the aluminum melt, improve the quality of the product, and does not affect the production process. The degassing unit is composed of box body, box cover, heating system, pore system, and refining system. It can effectively remove hydrogen, alkali metals, and other impurities in the […]

The slag removal ability of the aluminum degassing flux is determined by the adsorption and dissolution of the oxidized inclusions in the melt, and the chemical interaction between the flux and the melt. Because oxide inclusions are not wetted by molten aluminum, the interfacial tension between the two is very large. The flux wets the […]

Compared with the fiber filter and the straight-hole ceramic filter, the foam ceramic filter for casting can effectively filter out the inclusions in the molten metal. When the molten metal passes through the ceramic foam filter, the flow will decelerate, turning turbulent flow into laminar flow. As the foam ceramic filter changes the flow state […]
