Abstract

Patente de Invenção: "DISPOSITIVO PARA A FILTRAGEM E ADIçãO DE UM AGENTE DE REFINO DE GRãOS EM FUSõES DE METAL". A presente invenção refere-se a um dispositivo para a filtragem e adição de materiais de refino de grãos em fusões de metal com um primeiro filtro (10) e de uma alimentação para um material de refino de grãos, em que o primeiro filtro tem um meio de filtro poroso. A eficiência de filtragem do primeiro filtro (10) é substancialmente aperfeiçoada de acordo com a presente invenção ao se dispor a alimentação para o material de refino de grãos na direção do fluxo depois do primeiro filtro (10). As impurezas não dissolvidas introduzidas via o material de refino de grãos são removidas por meio do posicionamento de um segundo filtro (16) na direção do fluxo depois da alimentação para o material de refino de grãos. A única figura é provida para publicação com o resumo.
