Synopsis:Mathematical models are proposed for analizing blast furnace preformance. High pressure operation and oxygen enriched operation are studied with the proposed models. The production rate and the fuel ratio predicted from the models agreed very well with the operation data. Also, possibility of predicting production limit is discussed.

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.
