Abstract

resumo patente de invenção: "método para preparar escórias de fabricação de aço e aglutinante de mineral hidráulico". a invenção refere-se a um método para preparar escórias de fabricação de aço para produzir um aglutinante de mineral hidráulico com boa capacidade de endurecimento e para recuperar ferro. é fornecido um produto de alimentação que compreende escória de fabricação de aço que contém mno. o produto de alimentação é processado como um material fundido pela adição de um agente de redução ao material fundido. um fator de saturação de cal entre 90 e 110 precisa ser alcançado na porção mineral do material fundido. o material fundido é, então, resfriado de um modo definido e o ferro elementar é separado do material fundido solidificado. o material fundido solidificado é, então, usado como um aglutinante de mineral hidráulico.
