Determination of the Efficiency of Ceramic Foam Filters Based on Raw Materials and Industrial Wastes in Uzbekistan

摘要

The results of investigations of the filtration of melts through ceramic foam filters fabricated using raw materials and wastes in Uzbekistan are presented. It is shown that the filters developed with porosity 30 ppi effectively purify melts by removing exogenous nonmetallic inclusions and are just as good as industrial filters with similar porosity; the filtration efficiency depends on the particle type and size and equals 78% on average.
