Investigation on the Processing, Microstructure and Properties of Plate by TSCR for Cold Rolling

The technical characteristics of thin slab casting and rolling(TSCR),the rolling technology,the heated history of slab and the precipitation of second phase are analyzed.At the same time,the microstructure,precipitation,dislocation and mechanical properties of low carbon steel produced respectively by traditional process and TSCR technology are also investigated based on the statistical data of mechanical properties of the low carbon steel sheets produced by TSCR,the authors put forward a standard for composition and properties of basal plate for cold rolling,and provide a technique to settle the problems.The preliminary results of productive experiments on the metallurgic ingredient and technology controlling of plate by TSCR for cold rolling are provided.
