Abstract

The growing demand of high-quality casting is driving the use of ceramic foam filters in casting processes. The primary purpose of using a filter in a casting process is to remove impurities from the molten metal and to stabilize the flow of molten metal by slowing the flow rate. However, only a few studies have been conducted on the specific effects of ceramic foam filters on fluid flow during the casting process. In this study, a water model equipment is used to study the effect of ceramic foam filters on fluid flow, and commercial filters from three domestic and foreign companies are used. The reliability of the data obtained from the water model experiment is verified by an actual casting experiment. Finally, with the verified water model experimental data, the filter is modeled, and a computational fluid simulation is conducted to study the effect of the installation location of the filter on the casting.
