摘要

Using DRI/HBI in electric steelmaking involves handling a complexity regarding slag formers. The gangue that is a natural part of the material differs between DRI/HBI coming from different ore products. However, the full analysis of the DRI/HBI is not always declared or even asked for. Whereas scrap is specified into a number of different classes HBI/DRI is often handled as one single commodity. As a consequence the steelmakers might face problems with the slag if they do not observe the changing conditions. Having a nomenclature for different types of DRI/HBI pointing out these differences might be the first step to greater awareness of this problem. This paper uses eight calculation cases to illustrate the importance of slag considerations when evaluating DRI/HBI. Finally a way to classify them is given as a basis for further discussions.
