Synopsis:Molten iron is poured on the upper side of test piece which section closely resembles to blast furnace tuyere section currently in use. The lower side is cooled by forced circulation of water passing the horizontal rectangular channel. Specimens are oxygen free high conductivity copper(OFHC), 99.7% cast copper, 99.97% aluminum, rolled brass plate, aluminum bronze, mild steel and titanium. A transitional phenomena until burnout were observed and the effect of principal factors on the burnout heat-flux has been investigated. The results obtained are as follows.(1) In the case of OFHC, the burnout temperature of molten iron is higher as the velocity of cooling water is increased.
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.
