Experiments on the dissolution of a graphite-rod into liquid Fe-C alloy were made in order to discuss the mass-transfer in the inductively stirred liquid iron.
Average mass-transfer coefficient obtained from the change of concentration of carbon in liquid iron with time, does not almost depend upon temperature, but depends upon the power of the furnace.
Local mass-transfer coefficient obtained from the change in diameter of the rod, varies with the position of the rod, the frequency and the power of the furnace.
From these results, it seems that the flow conditions of liquid iron vary with the above electro-magnetic factors.
