Abstract: Since the nineties of 20 century the thin slab casting-direct rolling and the medium-heavy slab casting-Steckel Mill rolling technologies have been involved in production line of high strength low alloy(HSLA)steel,and in these processes a lot of available operation experiences of thermal-mechanical control process(TMCP)for production of HSLA steel have been achieved. At present the steel grades being developed by CSP(compact strip production)process are (1) ECC,UCC and IF soft steel;(2) high strength multi-phase DP and TRIP steel; and (3) X80 grade pipe steel. The characteristic and optimization of both processes for developing HSLA steel grade are presented.
