The foam ceramic filtering device is used for purifying aluminum liquid, it is applicable to all aluminum production departments, including sheets, strips, foils, bars, pipes, wires, extrusions, forgings, primary aluminum ingots, recycled ingots and continuous cast aluminum Production, rolling stock, etc.
Aluminum foil can be divided into industrial aluminum foil and packaging aluminum foil.
The chemical composition of industrial aluminum foil is relatively pure, with a thickness of 0.005-0.2mm. In the electronic and electrical industry, it is mainly used as capacitors, insulation materials, moisture-proof materials, etc.
The thickness of the packaging aluminum foil is generally 0.007～0.1mm. Products include flat foil, printing foil, color-painted printing foil, composite aluminum foil and other products, which are mainly used as packaging materials for food, tea, cigarettes, etc.
Aluminum foil rolling is rollless rolling, and the rolls are always in a state of elastic flattening. By adjusting the rolling force, rolling speed and controlling the tension in the rolling process, the thickness of the foil can be controlled.
Cast ceramic filters have porosities of various specifications and sizes, and are suitable for almost all aluminum plate, strip and foil processing plants.
The cast ceramic filter is composed of many uniform and numerous micropores. When the aluminum liquid passes through these micropores, the suspended matter is trapped on the surface of the filter medium, and the fluid passes through the micropore channels to produce various physical effects, so as to achieve the effects of mechanical filtration, purification, diffusion, and fluidization.
The foam ceramic filtering device adopts alumina ceramic foam filter for molten aluminum filtration, which can effectively remove various inclusions in the aluminum melt, greatly improve the cleanliness of the metal, and help improve product quality and reduce costs. Productivity has been improved to varying degrees, and the operation is easy, the process is easy to control, does not require excessive investment, and it is worthy of popularization and application.
