PROCESS TO MAKE A CERAMIC FILTER FOR METAL CASTING
A ceramic foam filter system includes a filter body having multiple tortuous path channels through the filter body to filter a molten liquid. A filter holder configuration defining a canister in a runner passage receives the filter body. An upstream end of the filter body receives the molten liquid having multiple inclusions. A predominant portion of the inclusions are larger than the multiple tortuous path channels and are trapped against the upstream end of the filter body. The multiple tortuous path channels are sized to trap a predominant portion of multiple oxides within the molten liquid as trapped oxides within the filter body. A filtered molten material having the multiple inclusions and the multiple oxides removed is directed from the multiple tortuous path channels as a discharge flow to exit at a downstream end of the filter body.
