摘要

Plant scale filtration experiments of 10"×l0"×2", 30PPi Al_2O_3 and SiC industrial filters were carried out. Wetting experiments show that the SiC filter wets better with molten aluminium than Al_2O_3. The assessments by LiMCA II and laser were employed to study the behaviour of the two filters. The Al_2O_3 filter shows improved time dependent behaviour, increasing filtration efficiency, during one hour filtration. This is not the case for the SiC filter. It decays faster than the Al_2O_3 one. The SiC filter requires less pressure drop to infiltrate the metal. The result suggests that the SiC can be a new filter choice in the aluminium industry.
