Summary

In recent years, interest in the filtration of molten metal has increased dramatically with a resultant increase in the variety of filter types and materials available. Of the more recently developed filters, ceramic foam filters have proven especially effective for the fine filtration of non-ferrous and ferrous alloys. The variety of ceramic foam filter materials, their geometries and pore sizes, and the still limited but rapidly growing theory of molten metals filtration make the proper selection and application of such filters a complex problem. Current understanding of molten metal filtration fundamentals is reviewed and applied to a variety of alloy systems. Guidelines are given for the selection and application of ceramic foam filters in various alloys.
