Foam ceramic filter is used in metal casthouse and as a new type of molten metal filter developed to reduce casting defects.<\/p>\n

The casthouse filter is used in the aluminum casting process to prevent molten slag and other harmful inclusions from entering the mold and eventually entering the final casting. Alumina ceramic foam filter is specially used to filter impurities in molten aluminum and aluminum alloy.<\/p>\n

Cleaner metals will produce higher-quality castings, less scrap and fewer inclusion defects, all of which help increase profits.<\/p>\n

The role of Casthouse Ceramic Foam Filter<\/strong><\/p>\n

1. Foam ceramics have high mechanical strength, chemical stability, and high resistance to thermal shock and liquid metal flow shock even in high-temperature environments.
\n2. Increase the compression and sealing of the casting, increase the elongation and tensile strength of the casting, improve the surface finish of the casting, improve the fluidity of the molten metal, and increase the filling capacity and replenishing capacity of the melt.
\n3. Simplify the casting system, reduce the length of side runners, and increase the yield of castings.
\n4. Reduce processing time and tool wear, and improve the surface quality of castings.
\n5. Reduce the gas and inclusions contained in the castings, reduce the turbulence of the molten metal when filling the mold, reduce the surface defects of the castings, and significantly reduce the rejection rate of the castings.
\n6. There is no slag inclusion or breakage during the working process, which ensures the stability of the quality and chemical composition of the molten metal.
\n7. With large and stable metal flow, even if the content of inclusions in the molten metal is high, the foam ceramic filter will not be blocked.
\n8. With high dimensional accuracy, it can be automatically put into the production line.<\/p>","protected":false},"excerpt":{"rendered":"
