| Abstract: | Based on the fact that ZIS succeed in manufacturing X52 and X56 pipeline steel by means of Nb Micro - alloying technology, and combined with the technical characteristic of TSCR, a series of technology to control thin slab continuous casting process for Nb - bearing steel were investigated, such as the schedules of pouring temperature, mold casting powder, matching slab withdrawing rate and heat flux density, and the selection of secondary cooling curve etc. |
