“…4(a) also shows the vortex in the region above the Kiss point, and the vortex is caused by the effect of viscous force and squeezing action of rollers together. Zhao et al [8] and Bae et al [11] also indicated the vortex was indeed existed and explained further that the vortex in this region could shear the dendrites to form new isometric crystals, and make the solute-rich molten metal flow back to molten pool for redistribution. The hypothesis can be verified by this mathematical model.…”

“…This liquidity can not only stir the inner zone of the molten pool, but also make the distribution of temperature and solutes more homogeneous. With the changing of temperature, the viscosity and mass of the molten metal may be also changed, but the flow rule still meets the continuity, the momentum theorem and energy equation [8].…”

“…Zhao et al [42] developed a mathematical model of twinroll casting of magnesium alloy. In their model, the authors considered the heat conduction coefficient of roll and strip was constant and the thermophysical parameters were the function of temperature but the casting speed was limited to 0.03 m/s to 0.06 m/s (2 rpm to 3 rpm).…”

Nowadays near-net-shape casting technology is an important area of research in the iron and steel industry. Among different kinds of near-net-shape casting process, twin-roll casting process has received much attention among researchers. Twin-roll casting (TRC) has been the subject of extensive research, not only to develop the technology but also to achieve an understanding of microstructural evolution and to produce quality strips. The main issues concerning the design and operation of twin-roll casters are metal-mold heat transfer, metal delivery system, and their possible effects on the solid shell formation and characteristics of the strips. The present review gives an idea about the process aspect, modeling, and quality issues in vertical twin-roll strip casting process and helps to improve the design of twin-roll strip caster.

Twin-roll strip casting is an effective technology to produce magnesium alloy strips economically. The aim of this work is to propose suitable (optimized) process parameters for manufacturing AZ61 strips using the twin-roll strip casting technology. Experiments on twin-roll strip casting of an AZ61 magnesium alloy were carried out. Temperature fields, fluid flow fields, and stress fields accompanying the process were simulated using thermal-fluid and thermal-mechanical finite element methods. The effects of casting speed and pouring temperature on temperature fields, fluid flow fields, and stress fields during the process were analyzed. It was found that the optimum pouring temperature should be in the range 690∼715°C and the optimum casting speed in the range 2.3 and 2.5 m/min.
