Abstract
The rate of dissolution of solid iron into Fe-C liquid alloy was studied in a temperature range from 1200 to 1420°C and for a range of initial carbon content from 4.0 to 4.3%.
The rate of dissolution was determined from the change in the bath composition. It was presumed that the data were consistent with a model based on simultaneous heat and mass transfer in the boundary layer between solid and liquid. Mass transfer coefficient estimated from this model was found to be in agreement with an existing dimensionless correlation for mass transfer.
In the explored temperature range, the thickness of diffusion boundary layer was 5×10-3-10-2cm.
This value was considered to be a reasonable parameter in the model of scrap melting developed recently by the authors.
