Alumina ceramic foam filter for aluminium casting
Alumina ceramic foam filter for aluminium casting plays a very important role in the aluminum liquid purification system.
The ceramic filter plate can effectively remove the large inclusions in the aluminum liquid and effectively reduce the micro inclusion size of the micro inclusions, improving the surface quality and product performance.
Improve the role of the microstructure and increase the yield. As long as used in aviation, transportation and other aluminum alloy precision casting.
Alumina ceramic foam filter for aluminium casting adopts three-dimensional mesh structure and organic carrier connected with air holes to invade special thixotropy special ZrO2 quality molten materials, adopting four-square correct center distance automatic extrusion technology,so that the slurry is evenly applied to the foam of the carrier.
On the skeleton, it is baked and cured at a high temperature of 1680°C and has an expanded cotton body sealing edge.
Technology and uses of Alumina ceramic foam filter for aluminium casting
Ceramic filter plate using three-dimensional mesh structure and connected to the pores of the organic foam as a carrier, it invades the thixotropic alumina slurry, the use of four square correction center distance automatic extrusion technology, The slurry was evenly applied to the carrier’s foam body skeleton and baked and cured at a high temperature of 1180°C.
Installed in the filter box for aluminum alloy liquid impurity filtration, to meet the production of high value-added, high-tech performance aviation, transportation and other aluminum alloy precision casting. Such as: computer hard drives, printing PS base, can making materials, jet turbine engine fan blades and other products.
The basic structure of ceramic filter plate: Ceramic filter plate consists of plate base, positioning seat, outlet, and surface film.
Alumina ceramic foam filter for aluminium casting is one of the core components of the ceramic filter. It is a new type of porous functional ceramic material, and its interior is covered with criss-crossing capillary pores (about 1 to 10 microns in diameter). This is the channel of the filtrate. This component is called the plate base layer. 2. The components of the ceramic filter plate are silicon carbide, corundum and other materials. The main components of the outlet and positioning base of the ceramic filter plate are composed of stainless steel or polymer material.
