Development and expection on high-efficiency producing technology of steelmaking in TSCR line

he thin slab continuous casting and rolling technology has developed for nearly 30 years. It has developed from the original single slab rolling mode to the present endless rolling. The continuous application of new steelmaking-continuous casting technologies runs through its entire development process，especially the continuous progress of the high-efficiency production and the slab defect-free technology，which has promoted the development of the thin slab technology. The development of the thin slab continuous casting and rolling production line was briefly reviewed，the development of key technologies of the steelmaking and continuous casting for the thin slab continuous casting and rolling production line was introduced，the characteristics and difficulties of each key technology and the progress made in the development of some key equipments were analyzed，and on this basis the development direction of the steelmaking and continuous casting technology of the thin slab continuous casting and continuous rolling production line was put forward.
