Determination of fixed carbon requirement in the production of high carbon ferromanganese in a submerged arc furnace

Abstract

“This work details the research performed on location in Marietta, Ohio in an attempt to determine the correct amount of ‘fixed carbon’ required for the production of high carbon ferromanganese. In order to analyze the fixed carbon requirement, several possible carbon-consuming mechanisms were singled out for study. These include the reaction of water with carbon, the Boudouard reaction, the recirculation of alkali metals via a mechanism that may consume carbon, the reduction mechanism of iron oxide, and the effect of mix resistivity.

Based on the information provided in this thesis, it is concluded that moisture fed in the raw materials may reach the coke bed and react with carbon. It is suggested that the Boudouard reaction does not occur to an appreciable extent. It is further concluded that the alkali recirculation probably does contribute to carbon consumption, however, perhaps not as highly as would be expected from the total recycle stream. The FeO is likely to be reduced directly by carbon. Calculations on mix resistivity infer that the coke requirement is affected by the mix resistivity”
