Resíduo industrial como matéria-prima alternativa para a produção de filtros cerâmicos refratários

The activities development of valorization of solid waste can facilitate the production of industrial products with high reuse potential as mineral alternative source. Currently, the industrial solid wastes have become an important line of research in Engineering. Nevertheless, few studies have been conducted with effective interaction of environmental, economic and social parameters that demonstrate applications of these raw materials in the manufacturing industry.In this paper are presented and discussed the research results related to the valorization of a solid industrial waste (ceramic shell) generated in the investment casting by lost-wax process.This material has very interesting features and suitable for the production of refractory ceramic filters.Thus, porous ceramics were obtained by the method of the replica polymeric and their performance tested in industrial filtering of cast iron liquid (1.76 kg/s). The produced metals components showed excellent surface finish.
