Casthouse Ceramic Foam Filters for Molten Aluminum

Alumina ceramic foam filters are mainly used for filtering aluminum and aluminum alloy in casthouse. These filters are machined to tight dimensional tolerances, are treated during processing, and have very low friability. Filter the inclusions in the casting, reduce the gas in the casting, reduce the turbulence when filling the molten metal, reduce the surface defects of the casting, and significantly reduce the rejection rate of the casting.

Casthouse Ceramic Foam Filter Manufacturers India Hindalco Industries Limited said that the correct selection and design of ceramic foam filters and filter holders are very important.

Casthouse Ceramic Foam Filters

Hindalco Industries Limited introduces that a sealing gasket is installed around the ceramic filter plate to act on the contact surface of the filter plate and the filter box to prevent the aluminum liquid from leaking through the contact surface.

AdTech Casthouse Ceramic Foam Filters use organic foam as a carrier, and these organic foams have a three-dimensional network structure.

Put the foam carrier into a special ceramic slurry with thixotropy. Then, the technician uses a special roll extrusion process to evenly coat the ceramic slurry on the carrier. The final ceramic filter plate after drying and solidification is fired at a high temperature. There is a sealing lining around the Casthouse Ceramic Foam Filter. It is mainly used for the contact surface between the filter plate and the Casthouse to prevent the aluminum liquid from leaking through the contact surface.

The ceramic foam filter makes the aluminum water fill the cavity more evenly. Molten aluminum has a higher tendency to turbulence during the casting process. The molten aluminum passes through the three-dimensional pore structure of the ceramic foam filter in the aluminum factory and finally transforms into a very stable laminar flow. Laminar flow can better fill the cavity, thereby reducing the impact corrosion of molten metal to the cavity. If you are interested in our products, please feel free to contact us.
