Storage, Handling and Shipping of HBI

摘要

This paper summarises work carried out to characterise the behaviour of fines based HBI during bulk material handling and storage. Fines based HBI was found to be stronger than pellet based HBI of similar density in tumble tests carried out to simulate bulk material handling operations. Drop tests showed that loading HBI will have a similar effect on a ship's double bottom as iron ore lump at equivalent loading rates. Corrosion measurements on an experimental HBI stockpile confirmed that corrosion losses in a stockpile are concentrated in a protective outer layer. Separate experiments highlighted the relationship between particle size, density, and corrosion rate.
