Ferromanganese is a ferroalloy with high manganese content which finds many uses for example as deoxidizer in steelmaking industry. However, there is very little data on the dissolution rate of carbonaceous materials in Mn containing metals. In this paper, the kinetic analysis of carburization reactions is investigated for Mn-Fe alloys. Dissolution rate of graphite in pure iron and four different alloys with 10%wt, 40wt%, 60wt% and 85wt% manganese at 1823K was studied. Results showed that the dissolution rate of carbon from graphite increased with increasing time for all alloys. The dissolution rate constant increased with the increasing manganese content from 0.65×10-2 cm/s for 0%Mn to 2.6×10-2 cm/s for 85%Mn.
