“…This is in contrast to the observations in the now obsolete Bessemer converter or the OBM process, where air/ oxygen is blown from the bottom. In the latter processes, appearance of a significant flame takes some time, which is assumed to indicate that carbon oxidation does not start till silicon has fallen to fairly low values (Orban et al 1961).…”

The Basic Oxygen Furnace (BOF) process is an exceedingly fast refining process needing a good dynamic model for better understanding and dynamic control. The process is characterised by reactions at multiple scales: at the scale of the metal bath and the slag and at the scales of droplets and bubbles. The reactions take place at multiple sites too. The presence of the supersonic jet interacting with the metal bath and the slag layer, producing various sizes of drops in the emulsion which on reaction produce copious bubbles at its interface, lime dissolution issues, etc., make the description of the dynamics of the process complex and fascinating. There are still areas where an adequate quantitative description needs further research.

“…Initially, the research consisted of studying the possibility that something could be added to the blast or to the nose of a Bessemer converter to suppress iron-oxide smoke. The results of this initial approach reported two years ago to this group 1 and to a meeting of AIME 2 encouraged further study. The work also showed that the research should be aimed at understanding the fundamentals of the smoke-forming process and the effect of specific variables on the rate of smoke evolution.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
