- Abstract
- Regulating thermal behavior between the solidifying shell and a mold is one of primary roles of the mold flux film during continuous casting of steel. This is particularly important as excessive heat flux through slag film will induce surface defects on cast steel. This study focuses on controlling radiative heat transfer through liquid slag film by utilizing finely dispersed metallic particles in commercial CaO-SiO2-CaF2-Na2O based mold flux system. In order to investigate the scattering effect on heat transfer during industrial casting processes, the extinction coefficient of various mold fluxes was measured using an FT-IR and a UV-visible spectrometer. Also, series of IET (Infrared Emitter Technique) tests were conducted in order to simulate mold heat transfer during commercial casting processes. Finally, it is found that the Mie scattering effect due to metallic particles will reduce the overall heat flux density through mold slag film by 10% or more. ? 2016 by The Minerals, Metals & Materials Society.
