Alumina foam ceramics are mainly used in the purification process of aluminum and aluminum alloy production, as well as various gas-solid and liquid-solid separation media, catalyst carrier, burner, sound absorption and environmental protection. It can effectively remove all kinds of inclusions with micron fineness in aluminum water, and make aluminum water become stable laminar flow, which is conducive to punching; It has superior resistance to aluminum water scouring, and can obtain stable filtering effect by strictly controlling the hole size and through hole rate; So as to improve the casting quality, reduce the casting scrap rate, prolong the service life and reduce the casting cost.
