Resumo
Against the backdrop of increasing the silica content of iron ore, Usiminas has adopted a strategy to add the pellet feed on sintering process in order to reduce this level and consequently reduce the production cost of hot metal in blast furnaces. To add this type of iron ore, which it was believed to be detrimental to performance indicators in conventional sintering, Usiminas acquired the intensive mixer. The ramp-up was characterized by gradual increases of pellet feed, burnt lime and moisture. It was used up to 25% of pellet coarse in charge of iron ore at sintering process.
