A mathematical model of the splat cooling process using the twin-roll technique

A mathematical model has been developed to represent the heat transfer, the flow of the solid and molten phases and the pressure distribution in the solid phase for the twin roll rapid quenching of pure metallic materials. The following main conclusions may be drawn from these calculations, which were carried out using the property values of aluminum. If roll spacing, feed rate and angular velocity of the rolls are considered to be main variables, then for a given material there exists only a narrow range of these parameters that affords stable operation.
