Feasibility analysis of producing hot rolled TRIP steels using TSCR process

As an advanced technology in steel industry,thin slab casting and rolling(TSCR)process has made a great progress since it has come into application from 1989.However,significant efforts have to be made to expand the product family of TSCR.Being of excellent combination between strength and plasticity,low alloy TRIP steels are paid a considerable attention for auto use in recent years.In the present article,the feasibility of the production of hot rolled TRIP steels using TSCR process was analyzed.It was pointed out that insufficient time for the formation of polygonal ferrite was a key problem for the production of hot rolled TRIP steels using TSCR process.The methods used to solve the problem were discussed.
