“…6) The application of Computational Fluid Dynamics (CFD) has proven to be extremely useful in modeling the HSBC process. Numerical analyses were conducted, emphasizing aspects such as heat transfer, 7,8) casting substrate characteristics, 9) general flow and solidification, [10][11][12] and electromagnetic behaviour, 13) pertaining to the HSBC process. The medium-strength 5000-series aluminum alloys containing magnesium exhibit high ductility, good corrosion resistance, as well as good weldability.…”

Horizontal Single Belt Casting (HSBC) is a near net shape strip casting technology that will probably gain significant prominence in the coming years. Fluid mechanics and associated heat and mass transfer are important aspects of any continuous casting process, and the HSBC process is no exception.In this study, mathematical models have been developed, using ANSYS FLUENT 14, to assess various aspects of the HSBC process for the Al-Mg-Sc-Zr system. Specific emphasis is placed on a) the effects of substrate surface properties on strip quality, b) liquid metal-air two-phase interactions and meniscus behavior, c) heat fluxes between the metal and substrate, and d) solidification behavior during strip casting.These predictions are validated against experimental casting results. A 5000 series Al-Mg alloy, with added Sc and Zr, shows exceptional potential as a structural material for aerospace and transportation applications. It is also a suitable material to be produced via the HSBC process. Optical microscopy, SEM and EBSD analyses were conducted to compare the potential advantages of casting this alloy via the HSBC process versus conventionally produced Direct Chill Casting.

“…They coupled the fluid flow and heat transfer in this model and incorporated interface search scheme on local transformation technique to reduce the complexities of the model, which helped to easily handle the different materials behavior and discontinuity of material properties along different phases during simulation. A threedimensional fluid flow, heat transfer, and solidification model was developed by Guthrie and Tavares [30] to study different metal delivery systems for twin-roll casting using METFLO code. These simulations applied to a pilot caster being studied in Canada with roll radius 0.30 m producing steel strips with thickness ranging from 4 mm to 7 mm at a relatively low casting speed of 0.06 m/s to 0.2 m/s (5 rpm to 7 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.
