Foundry Size Ladle Metallurgy Vessel: Ferromanganese Dissolution
This paper examines the dissolution rate of low carbon ferromanganese in steel. Forty-five kilogram (100 pound) heats were induction melted and poured into an unfired vessel fitted with a bottom porous plug for argon stirring. Alloy additions were made and timed samples taken to evaluate the effect of different gas flow rates, alloy particle sizes, and alloy concentrations on dissolution rate. In this study, it was found that for alloying to a nominal 0.30% manganese, ferroalloy particle size was more important to dissolution kinetics than gas flow rate, for the conditions examined. when alloying to 1.0% manganese, no clear correlation was observed due to alloy particle agglomeration. Activation energy could not be determined because of the rapid cooling during the experiments.
