| Abstract Scope |
The development of process for high-speed thin slab continuous casting is one of the most important recent trends to increase the productivity. However, the special funnel-type mold and higher casting speed always lead to an unknown and drastically changing heat fluxes. Thus, accurate quantification of heat flux during high-speed thin slab casting is essential for the production quality control. A novel method for the estimation of the heat flux across funnel-type mold based on the measured responding temperatures from two surfaces of thermocouples that embedded inside the mold has been developed. The method includes a Three-Dimensional Inverse Transient Heat Conduction Problem (3D-ITHCP) model that is solved by the conjugate gradient method. The result of the method applied to a mold simulator experiment shows that the maximum heat flux is located at the transition region of funnel shape bottom as high as 3.14 MW/m2. |
