Molten Metal Filter Technology for Aluminum Purification

In casting production, casting waste caused by casting defects such as non-metallic inclusions generally accounts for 50% to 60% of the total number of waste products. The use of molten metal filter technology can effectively reduce or eliminate various non-metallic inclusions and purify liquid casting alloys.

The ceramic foam filter uses polyurethane foam as a carrier. After hydrolysis, it is immersed in a coating made of ceramic powder, binder, sintering aid, suspending agent, etc., and then squeezed out the excess coating to make the ceramic coating evenly coated. It is applied to the carrier skeleton to become a green body, and then the green body is dried and baked at a high temperature.

Molten Metal Filter Technology

The alumina ceramic foam filter is mainly used in the purification process of aluminum and aluminum alloy production. Molten Metal Filter Technology can effectively remove various inclusions in the aluminum water with a fineness of up to micrometers, so that the aluminum water becomes a smooth laminar flow, which is conducive to flushing, has excellent water brush resistance, and strictly controls the hole size and through-hole rate. Can get the effect of steady walking. Thereby improving the manufacturing quality, reducing the scrap rate, prolonging the service life and reducing the cost.

Large-size oxidized foam tiles (passing boards) are widely used in aluminum melting workshops such as aluminum alloy rods, flats, aluminum foils, aluminum products, and high-end aluminum profiles. The removal rate of 15 to 20 meters of impurities is 98.3%, which can help to obtain perfect aluminum is produced in various specifications according to depositors’ requirements.
