Dissolution of solid steel cylinder into molten Fe-C alloy was investigated at the temperature from 1300℃ to 1500℃. In this paper, the viscosity and the density of the melt and the diffusion coefficient of carbon were estimated from the literatures at the solid-liquid interface i. e. at the liquidus concentration of carbon, C_L. Nondimensional correlation for the mass-transfer was analysed using above estimated physical properties and diffusion coeff. Correlation for the rotated or static cylinder was obtained as follows : J_D=(k/U)(S_C)^<2/3>=0.064(Re)^<-0.25> 10^2<Re<10^4 : rotated cylinder Sh=0.11 (Gr・m×S_C)^<1/3> 10^9<Gr・m×S_C<10^<11> : static cylinder Utilizing the nondimensional correlation of a model test by benzoic acid-water system, the unknown rates of stirring of molten Fe-C alloy melted by some laboratorial H. F. furnace could be roughly estimated from the rates of dissolution of steel cylinder.
