Abstract

- A number of injection trials carried out over the years at the LKAB experimental blast furnace (LKAB EBF®) and in industrial BFs shows that tuyere injection is a feasible method for supply of various types of pulverized materials as different types of PC, BOF slag and BF dust to the BF. In this study, the effect on process, raceway conditions, hot metal quality, reductant agent consumption and slag formation due to the selection of injection materials are discussed based on trial data. A special attention is paid on the injection of alternative carbon containing residual material. Based on recent trials the efficiency in use of carbon in injected residual materials are discussed and pilot scale results compared with industrial trial results.
