Techniques in the study of carbon transfer in ironmaking
In this paper two new approaches to the study of carburisation/decarburisation of iron are detailed. Firstly, a new experimental method focusing on understanding carbon transfer in a non-traditional ironmaking process, and secondly, a new carbonaceousmaterial (coke analogue) for use in coke laboratory investigations are detailed. The new experimental method was developed to assess the decarburising effects of high titania slags, typical of ironmaking with titaniferous ores or sands. Preliminary experiments found that carbon was being consumed from the metal as it passed through the slag. The coke analogue was developed to address material complexity and heterogeneity issues that often limit and mask important coke phenomena in laboratory studies. Preliminary dissolution experiments using the coke analogue to carburise iron showed that rate of dissolution was consistent with that published for both graphite and industrial coke.
