The Ceramic Foam Filter Novokuznetsk Aluminum is manufactured based on a solid network structure and a carrier with organic foam cells. The preparation process is that the carrier is put into the thixotropic alumina slurry, and the angular center-positive pressure automatic extrusion process is adopted to uniformly deposit the slurry on the carrier foam skeleton […]
After placing the ceramic foam filter in the filter system, the filter produces a comprehensive resistance to the liquid casting alloy. This resistance mainly includes: Thermal resistance: The resistance caused by the temperature difference between the high-temperature molten metal and the filter. Force resistance: At the entrance of the filter, a large stream of molten […]
There are many kinds of filter mechanisms. Take the ceramic foam filter as an example to illustrate the main filtering mechanism. The filtering mechanism of ceramic foam filter includes mechanical filtration, rectification, filter cake function, adsorption. Mechanical filtration: When the molten metal flows through the ceramic foam filter, inclusions larger than the pore diameter are […]
