Modelling of fluid flow, heat transfer, solidification in the strip casting of copper base alloy. Part 2. Heat transfer

A finite-volume model has been developed and applied to compute the fluid flow, temperature and heat flux distribution within the liquid and solid zones in the mould region of a pure copper continuous strip casting machine. A fixed solidification front between solid and liquid is assumed. The model was produced with the commercial program CFX, which allows this non-linear, highly turbulent problem to be simulated using the k-ε turbulence model. The effect of casting speed on heat transfer was investigated. The predicted temperature distribution and heat fluxes were compared with experimental measurements, and reasonable agreement was obtained.
