Ceramic Filter Suppliers Provide alumina ceramic foam filter for export which is used in the aluminum metallurgy industry and foundries to remove non-metallic inclusions and metal melt in the oxide film.
Before use, it is important to preheat the filter and filter box.
During the preheating process, care must be taken to control the heating rate and temperature distribution. This can minimize the thermal shock and stress in the refractory material of the filter and filter box.
During the casting process, due to the three-dimensional structure of the filter, the metal flow is effectively stabilized, making the mold smoother and filling more uniform.
It is usually applied by placing an alumina ceramic foam filter in a filter box. The filter has excellent corrosion resistance and molten aluminum corrosion performance, can effectively remove inclusions, reduce residual gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metals can produce higher-quality castings, reduce scrap, and reduce inclusion defects, all of which help increase profits.
