Popis: The rising demand for steel products with the simultaneous search for a more cost-saving and environmentally friendly operation mode makes the efficient use of raw materials a key factor in iron and steel making. Within this research project, different types of lump ferrous burden material were studied, namely lump ores, pellet brands, and sinter samples of industrial scale use. The scientific analysis was done concerning their reducibility performance, mechanical stability before and after the reduction procedure, and their morphological evolution during the conversion from oxide to metallic iron. The different testing procedures led to a better understanding of what happens during the reduction and contributed to finding a correlation between raw material properties and their performance during the reduction process. However, to predict the behaviour of the different types of ferrous burden within any industrial scale process, testing procedures that are most closely related to the actual process parameters are needed.
