Progress and Prospect of Thin Slab Casting and Rolling Process in China

摘要

Thin slah casting and rolling (TSCR) production has made much progress in China. Not only productivity has been improved gradually, but also products development has special characteristics in some steel plants. Much progresses in producing fine and ultra fine grain steel and Nb, V, Ti microalloy ed high strength steel, improving hot strip quality for cold rolling, increasing ratio of thinner strip output and developing ferritic rolling technique have been made also. Even depositions strengthen mechanism of nano -precipitates has been studied deeply. Some equipments and relative techniques of TSCR are developed domestically. The problem about influence of route on productivity, quality and process structure will be paid more attention in order to improve the competitiveness of TSCR in future.
