Abstract

"APARELHO E PROCESSO PARA O SUPRIMENTO DE MATERIAIS DE ALIMENTAçãO SóLIDOS PARA UM PROCESSO DE REDUçãO DIRETA". Expõe-se um processo e aparelho para o suprimento de materiais de alimentação sólidos para um processo de redução direta para lanças de injeção de sólidos de um vaso de redução direta. O aparelho de suprimento de materiais de alimentação inclui uma linha de suprimento (L) para transportar material que contém ferro e material carbonáceo sólido sob pressão para lanças de injeção de sólidos (7), e a linha de suprimento inclui uma seção de linha de alimentação principal (15) e uma pluralidade de seções de linha de derivação (17) que se estendem a partir da seção de linha de alimentação principal. Cada seção de linha de derivação está conectada a uma lança de injeção de sólidos para abastecer material que contém ferro e material carbonáceo a essa lança. O aparelho inclui ainda um conjunto para distribuir material que contém ferro sob pressão para a seção de linha de alimentação principal da linha de suprimento e um conjunto para distribuir material carbonáceo sob pressão para a seção de linha de alimentação principal da linha de suprimento.
