Abstract
Accurate quantification of heat flux during high-speed thin slab continuous casting is essential for the design and development of the products as well as operation and quality control of the casting process. A novel method for the estimation of the funnel-type mold based on the measured responding temperatures from two surfaces of thermocouples that embedded inside the funnel mold during continuous casting has been developed. The method includes a Three-Dimensional Inverse transient Heat Conduction Problem (3D-IHCP) model that is solved by the conjugate gradient method. The results indicated that the heat fluxes and temperatures across funnel mold hot surface calculated by 3D-IHCP show the same variation tendency as those calculated by 2D-IHCP. Nevertheless, the heat fluxes calculated by 3D-IHCP are larger than those calculated by 2D-IHCP for the locations below the meniscus at the funnel and transition region, but are closed to those calculated by 2D-IHCP for the other positions due to the inclined wall of the funnel-type mold and the convex mold curvature.
