Strip Casting Techniques for Steel.

Abstract

The concept of casting molten steel directly into strip can be ttaced to the work of Sir Henry Bessemer, A version of Bessemer's concept can be seen in state-of-the-art continuous casting techniques for large section slabs, and an extension of CC slab casting knownas thin slab casting is also nearing commercial use. On the other hand, the development of a practical strip caster with thickness ranging from several hundred microns to about IO mm is still in the research stage. This paper describes the main trends in the developmentof strip casti ng techniques in terms of both processes and material characteristics. Thetwin-roll caster is the main trend in Japan, while the single-roll caster forms the mainstream in the United States.
