PRODUCING THIN STRIPS BY TWIN-ROLL CASTING .2. PROCESS MODELING AND DEVELOPMENT

Extensive modeling work has appeared over the last decade and has contributed significantly to the fundamental understanding of the physical phenomena involved in twin-roll casting, such as fluid flow, heat transfer, and thermomechanical processing. The commitment of metals producers to the technology is strong, which is evidenced by numerous pilot-scale casters that have been constructed worldwide. Together with the process models, these casters have been instrumental in developing new process designs and in improving and optimizing the performance of existing twin-roll casters. Current R & D efforts are intensive in both the aluminum and the steel industries, with the former aiming to gain a higher productivity and the latter striving to scale up from pilot plants to commercial production.
