Application of Inverse Heat Transfer Technique in Thin Slab Continuous Casting for Estimating the Interfacial Boundary Heat Flux

Abstract

The funnel-shaped moulds used in thin slab continuous casting process does not permit the usage of conventional process such as thermal resistance networks for determining the interfacial boundary heat flux. Empirical heat flux correlations mentioned in the literature were not suitable to use for funnel-shaped moulds used in thin slab casting since they are developed for billet or thick slab casting processes. An efficient inverse algorithm, called salp swarm algorithm (SSA), is used in this study for determining 3D interfacial boundary heat flux profile on hot face of the funnel-shaped mould. This study also explored the minimum number of sensors to be placed inside the funnel-shaped mould for accurate estimation of the interfacial boundary heat flux.
