sob Redução), pode-se determinar a geração de finos durante a redução da carga metálica no alto-forno, e com o RI (Índice de Redutibilidade) determina-se a capacidade do sínter em ceder oxigênio para o gás redutor. São ensaios de extrema importância, pois com o RDI é possível medir a degradação do sínter quando submetido a condições redutoras do alto-forno, e com o RI entende-se o grau de redução da carga metálica momentos antes do início de seu processo de amolecimento. Com a instalação deste forno no Laboratório de Redução da CSN, será possível correlacionar os componentes do sínter, e de outras cargas metálicas, avaliando suas influências no produto, e, consequentemente, em suas utilizações no alto-forno.

FURNACE INSTALLATION FOR TESTING OF REDUCIBILITY (RI) AND LOW-TEMPERATURE REDUCTION-DISINTEGRATION INDICES (RDI) AbstratWith the RDI test (Low-Temperature Reduction-Disintegration Indices), it´s possible to determine the fines generation during the reduction of the metal charge in the blast furnace, and, with RI test (Reducibility Index) determines the capacity of the sinter in giving oxygen to the reducing gas. These tests are extremely important because with RDI it´s possible to measure the sinter degradation when subjected to reducing conditions of the blast furnace, and RI refers to reduction degree of the metal load moments before the start of the softening process. With the installation of this furnace in CSN´s Reduction Laboratory, it will be possible correlate the sinter´s components, and other metallic fillers, evaluating its influences on the product, and hence their use in the blast furnace.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
