A Comprehensive Study of Ceramic Foam Filtration

摘要

A comprehensive study of ceramic foam filtration in Ixxx series wrought alloys is presented. This work encompasses filtration efficiency determinations with and without the influences of grain refiner, as well as fundamental studies on filter pore structures and associated fluid flow. New findings are described and have been used together with the program's previous findings to develop a somewhat revised perspective on the in-line treatment process. This is manifested specifically in the development of a filter concept for aluminum alloys which is to be tested initially tor wrought 1xxx series alloys. This filter concept is intended to capture fully the potential benefits of ceramic foam filters whilst offering protection against any possible fluctuations in grain refiner quality.
