Foundry alumina ceramic filter mainly for filtration of aluminum and alloys in cast houses. The filter can effectively remove inclusions, reduce trapped gases and provide laminar flow, so the filtered metal is significantly cleaner. Cleaner metal results in better quality castings, less scrap and fewer embedding defects, which contributes to the bottom line. Features of Foundy Alumina Ceramic Filt ...

Inline degassing equipment mainly processes molten aluminum containing a certain amount of hydrogen and other residues (alkali metal, inclusion of slag), which are removed after being processed by degassing equipment. The principle of inline degassing equipment is the principle of gas flotation. Process gas (inert gas or mixture of inert gas and chlorine gas) is injected into the melt through the ...

As the demand for premium aluminum products increases, especially in the aerospace industry, the need to reduce the occurrence of inclusions in molded products also increases. A popular remove hydrogen method is to introduce nitrogen gas bubbled through liquid aluminum. The hydrogen is attracted to the nitrogen bubbles, then transported through the aluminum and released to the surface. Argon is al ...

Aluminum degassing agent is a white powder or granular stream, which is prepared by drying a plurality of inorganic salts and mixing them in a certain ratio, and is mainly used for removing hydrogen and oxidized slag floating inside the aluminum liquid. The aluminum degassing agent is mainly used to remove the hydrogen inside the aluminum liquid and the floating oxidized slag, so that the aluminum ...

Porosity is the percentage of the total volume of cavities in the ceramic foam filter plate product relative to the total volume of the filter plate product. Porosity determines the filtration capacity of the ceramic foam filter plate per unit volume. The greater the porosity, the greater the filtration rate of the filter plate and the greater the filtration capacity, and vice versa. Porosity dete ...

The ability to degas molten aluminum is generally achieved by using an inert gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced into the melt, they collect hydrogen as they float to the surface. The best possible situation is that these hydrogen saturated bubbles leave the melt and reduc ...

The rotary nitrogen degassing unit provides more complete removal of hydrogen compared to degassing the flow. In addition, the rotary degasser does not use harmful salts containing chlorine and fluorine. The rotary nitrogen degassing unit can also combine the functions of degassing and flow introduction. In this case, the inert gas serves as a support for the granulated stream. The method is calle ...

In the rotary method of the aluminum liquid degasser, an inert or chemically inactive gas (Argon, Nitrogen) is purged through a rotary shaft and a rotor. The energy of the rotating shaft causes the formation of a large number of fine bubbles offering a very high surface/volume ratio. The large specific surface area promotes rapid and efficient diffusion of hydrogen into gas bubbles, which helps to ...
