Abstract

A new approach by applying the Monte Carlo method has been developed to estimate the radiative component of heat transfer of a mold flux film in the continuous steel casting process. The variation of total heat flux in the mold flux film for continuous casting of steel is calculated as a function of scattering albedo for cases with and without contact resistance between the mold flux and the mold. The scattering albedo of the crystallized mold flux was also determined from the measurement of the ratio of transmitted laser beam intensities through two samples of different thicknesses. Eight to thirty% of the total heat flux in the mold flux film is induced by crystallization, due mainly to the change in absorption of the radiative component.
