“…Por ello, al objeto de poder simplificar la resolución del problema, T. Saitoh et al [54] , basándose en un modelo previo [55] , han desarrollado un modelo bi-dimensional, en régimen estacionario, para el campo de velocidades y perfil de temperaturas, considerando, en todo momento, una interfase sólido-líquido fija y para cuya resolución se han empleado las ecuaciones generales del movimiento del fluido así como las ecuaciones correspondientes a la transmisión de calor.…”

“…Process modelling [2] has been introduced in order to improve quality, reduce production cost, and improve safety. Like most commercial material processes, the twin roll casting involves many interacting phenomena of great complexity, which makes it difficult to include them all in the model.…”

Industrial twin-roll casting of aluminium alloys requires optimisation of connections between process parameters and product properties. To a large extent, the cast strip properties depend on the spatial and temporal characteristics of heat transfer from the cast strip, which needs estimation of the influence of process parameters on the temperature field and temperature gradients in a strip for various alloys, which are cast on an industrial machine. For this purpose, the recently developed meshless Local Radial Basis Function Collocation Method (LRBFCM) was used in the simulation of heat transfer from the strip. The solution of the nonlinear convection-diffusion equation is based on a mixture continuum formulation of the energy transport in solid-liquid phase change systems. Simulation results were compared with experimental values, which were obtained during the industrial production process. They were measured in situ by the specially designed apparatus with fast response thermocouples, which can measure the time-dependent temperature of the cast strip in several locations on the moving strip surface simultaneously. The time-dependent measurement was coupled with a digital camera recording to gather the spatial domain measurement of temperature. The differences between the numerical simulation and experimental results were smaller than 6 K. An explanation for the discrepancy is given.

“…Various mathematical models [2][3][4][5][6][7] have been suggested in the literature to predict the fluid flow, heat transfer, and solidification in twin-roll casters. Most of the papers deal with fluid flow modeling in vertical twin-roll casters, but only a few papers 6,7) deal with the fluid flow modeling in horizontal twin-roll casters.…”

A two-dimensional finite element based mathematical model of coupled turbulent fluid flow, heat transfer, and solidification in horizontal twin-roll thin strip casting was developed. Basic formulations for simulating the coupled thermal and flow fields are described in this paper. A k-ε turbulence model was used to calculate the turbulent viscosity in the melt pool. A variable viscosity model was used to model the mushy region. Inlet velocity, strip/roll heat transfer coefficient, alloy composition, and melt superheat were the main process variables considered. The effect of the above process variables on the sump depth, mean strip exit temperature, roll surface temperature, and temperature gradients inside the roll, was analyzed.
