Abstract

"FáBRICA E PROCESSO DE FUSãO DIRETA". A presente invenção refere-se a uma fábrica de fusão direta e a um processo de fusão direta para produzir metal fundido a partir de um material de alimentação metalífero, tal como minérios, minérios parcialmente reduzidos, e correntes de resíduos contendo metais, esse último compreendendo as etapas de (a) pré-tratar o material de alimentação metalífero em uma unidade de pré-tratamento e produzir material de alimentação pré-tratado tendo uma temperatura de pelo menos 200<198>C, (b) armazenar o material de alimentação metalífero pré-tratado tendo uma temperatura de pelo menos 200<198>C sob pressão em um meio de armazenagem de material de alimentação quente, (c) transferir o material de alimentação metalífero pré-tratado tendo uma temperatura de pelo menos 200<198>C sob pressão em uma linha de transferência de material de alimentação quente até um meio de entrega de sólidos de um recipiente de fusão direta, e(d) entregar o material de alimentação metalífero pré-tratado no recipiente de fusão direta e fundindo o material de alimentação metalífero em metal fundido no recipiente.
