Abstract:Developments of thin-strip casting of steels and thin-strip casting and rolling of aluminium alloys were summarized, and the experiment researches on thin-strip casting of high-speed-steel, silicon steel and magnesium alloys were briefly introduced. The results show that the thin-strip casting of steels has been advanced remarkably and will be fastly developed in the coming 10 years. The thin-strip casting can be combined with special alloys or alloys hard to process so as to make full use of advantages of rapid solidification. Casting speed of aluminium alloys can be probably increased by vertical twin-roll thin-strip casting, especially that with large solidification temperature range. And also the thin-strip casting of magnesium alloys should be thought much to improve the plastic processing and corruption of magnesium alloys.
Key words: thin-strip casting; development status; casting speed; magnesium alloys
